And this example is that the diameter here equals the same as this diameter here. Drag my cursor down and then place the datum feature down on the drawing with the left mouse button. I make this line as perpendicular as you can to the geometry reference line. 34. You can also create isometric views by projecting a view to a diagonal position. And to escape the section view, we just simply hit the cross. Welcome to the Onshape forum! In this case, two of two. The 2D technical drawings to duplicate and 3D modelsare provided in PDF and STP format, and are. Insert a row below, insert a column to the left of the cell or to the right. Standardization aids clarity and understanding by all parties involved. If you only have one dimension in your sketch. So to create this drawing, I've chosen to use an A3 page size and I'm using third angle projection. We get a curved line to create a shape so that the crop line doesn't confuse a machinist and being part of the geometry. Double-click the sheet you want to view; the currently displayed sheet is highlighted in blue with a vertical blue bar to the left. And that's a depth. If the component is out of balance, undesired vibrations could be present. Be respectful, on topic and if you see a problem, Flag it. Our view is then cropped. Though the UK, where I'm from, uses a full stop or period. This 59 will just be 0 decimal places. You may notice that on shape wants us to place the view diagonally, which we can do by left clicking as normal. Easy. So I can do that the same height. What I still didn't find is the parts tree on the left side, or rather I see something in the assembly view, but I don't see the appropriate menu item. Similarly, in the first angle projection convention, the view from the top view d, is placed below the main view. It is okay to have the export done in multiple file formats, but even recommend this. Inserting Section Views: Section views are extremely helpful in engineering technical drawings for showing details that would otherwise not be possible to dimension properly. But this will get more difficult to determine when you have multiple section views. Welcome to the Onshape forum! To insert a bill of materials table, we first need to populate our bill of materials in the assembly workbench. All other note for this view, for gerund face to be shielded during a shot peening. So I'll leave it as an exercise for you to carry out on your own. I front view, for example, does not adequately describe this component. So I can select the right plane and we get a section. I like to set these lines of the geometric tolerance as vertical and horizontal lines, which you have to do manually. Note our extension lines do not quite touch our geometry. (2D Drafting of a Race Car Suspension Hub, image below). You can then select the picture, move it about, and resize as desired. Flattened is where all components in the assembly will be detailed in the bomb without showing a relationship of components to subassemblies. Just drag this down a bit, and then I think it would go to. Okay? Well, on the first view. The template names help us with further information too. I try and make sure that none of the components overlap. the work arounds are simply cumbersome, especially extruding a sketch, making a new scaled part, and then working backwards to make a sized up or down sketch. And then we just need to add an a password and meet all the password requirements. Ask questions and join in the discussions about everything Onshape. I know in this instance that I'll need A1 size sheet of paper. But be careful not to clutter your drawings too much if you have a lot of holes with all these center lines on this view, I'd almost say that it is too cluttered. The table usually comprises of reference number, part number, where revision numbers should also be present. For example, you may like the steel parts to be coated in a thin film of oil and placed in wax paper. I am still keen for something here. And then we'll put in plus minus again space no 0.125 millimeters. This part really wants to have a section view aligned to its rotation axis. When a view reference is pinned, a pin icon appears along with the name of the version it is pinned to, as shown below: Similarly, select Unpin view reference to remove the pin and allow the reference to be updated again. We can edit the note the same as when we double-click on the note itself. Be respectful, on topic and if you see a problem, Flag it. And to this point here. 10. Fortunately I only spent 10 minutes drawing it but when I put a dimension on only the dimensioned line scales which ruins the drawing. We can place that down. Selecting two neighboring cells and the same column allows even distribution of row heights. How it is. I wanted to remember third angle projection could be that the placement of a view is on the side of the viewing direction. Okay. There we go. By double-clicking on the cut lines. This is the easiest dimension tool to use as it takes as little as three button clicks and there are no options to illustrate how the tool works and to understand the dimension text. So do the same with the 60. Until you get to these angled sections. Then click Okay, which will populate our title block. And what I'm, what I would say as well is the way in which you dimension this is important. When we are at this step. This is particularly helpful when communicating with a supplier or a colleague, when speaking with them on the phone or via email. Usually though, the main purpose of balloon referencing is the cool, the item number. All of the Onshape-supplied drawings templates have the following automatic referencing between the drawing's properties and the title block: If no Documentation name is defined in the user Account profile settings, then the Nickname property is used. 6. So it might be one worth remembering. When viewing the sheet in the landscape, which has a border of 20 millimeters from the trimmed edge as per the standard. Under the relevant sheet. Only points are highlighted. As they are so large. We unfortunately don't get a view arrow like we do with details or section views. You can just bring it down just a slight, slight amount. This next line represents a tolerance of plus or minus 0.25 millimeters for dimension value with one decimal place. Students and hobbyists can get easy access to unchecked for free today, this class covers the core features of technical drawing creation, but on shape also offers 3D modelling, sheet metal design, and assembly design to ensure you truly learn how to use on shape. You can click on this line in the front view to learn the axillary view normal to this line. I'll show you why later on. This means that our Lei is approximately perpendicular. So from here to here is going to be 20, from here to here is going to be 40. Cat drawings are typically constructed from two line weights, that is the thickness of the lines. This is what we're looking for. We can measure that on this section view here. If you move one, whether you move that parent or the child view. We'll add our arrow. You may find a note in small font next to your Boolean reference, which refers to the quantity of components. Welcome to the Onshape forum! The issue with this second method is that you may have wanted this first few you placed rotated round by certain degree. The sheet names will however, have to be updated manually. Once you select the DWTfile, the sheet format is applied to the currently displayed sheet in your drawing. You need to reference the scale of that view. Welding is a colon process that melts and fuses two metals together. On the second tab. Let's have a look at how we would specify a surface finish on a component. I can change the precision with this drop-down menu to see that are typed number remains and it is just displayed as a rounded number. Once we're happy with our settings, we are able to move the view around the page freely by selecting a view, by clicking the left mouse button and dragging it around the page. Then take the suppress alignment with parent option. Notice that all of the holes have been highlighted and we have an empty table previewed on the sheet. We can resize and format or table in a similar way in which we could format normal tables. Okay? Check out the, Please submit support tickets for bugs but you can request improvements in the. Then we can right-click on the letter and select Add leader. We then need to pick two points on the drawing for where we want the pictures to go. Thisproject relies on you creating 2D Technical Drawing from a 3D CAD model. This is one of the reasons why you weren't get a straight line for cropping. So what I've just described to you is the Solid Works variant. Even for isometric views. And the process might be something you'd find in the notes. So there is the video solution to project 5.1. Remember that if what you are doing adds clarity, it is luckily the right thing to be doing on a drawing. We can double-click on the view and increase the scale up to one-to-one for this component. Going back to the on-chip folder, we can display all templates, just NC templates or just IC templates. So I'm just going to remove that scale label. Looking for a certain topic? Well again, we precision of one decimal place. To show these three methods, I'll open up an, a nought sheet. So if we select Front in this 2D drawing, we get this view of the part. If we need to reposition dimensions, we can do so with the left mouse button on a dimensional value and drag, where unfortunately, we also move the dimension value. I tend to work with ICER. Like with a detail view, you need a view to start from. And the last parameter that you'll likely use often is this scale label radio button. At this point you can adjust properties like Scale and Reference in the Sheet properties dialog. A recent feature introduced was this diameter two radii toggle. 9. I also recommend section of the starter zones to originate from the top-left so that you are in line with the most widely accepted drawing standard, British standard 8888. Now 27.5 should just be with one decimal place. And because this is the first revision, this will be revision one. Well, we are about to place the dimension. Most CAD software that I've used will able to view and add a scale label. And this location will snap to a line or feature on the component signified by the small brown shapes that are pair. Box e is used if you want to specify a machining allowance given us a number in millimeters. For an example, this isn't the best way to dimension this feature. Once its a solid or a sheet you can use the Transform feature to scale it: Colleagues! So if there are any other shortcuts you'd like to know about, you can press this question mark and then go to keyboard shortcuts and it comes up with a full list. So one of the brilliant things you can do in on shape is you can actually do a second section. You will have noticed that there are other fields on this menu for surface finish symbols. Projection symbol to terminate whether the drawing is working in first or third angle projection. We can add parentheses to our dimension, which usually signifies reference dimensions, meaning that they shouldn't be used for manufacturing or inspection. We need to have our DXF or DWG file, upload it to our own shape account. Welcome to the Onshape forum! It maintains clarity for our drawings. For our case. Note how at one-to-one, our global scale, the scale label is not automatically ticked. So you can continue to add center lines without having to keep picking this tool. We can also change the Arab position of the dimensions by left clicking on the brown diamond. That is what is holding you back. These pitch circle diameters are not always the cleanest way in which to represent a pitch circle diameter. If we have more than one WHO in a part with exactly the same hole type and size. PTC Onshape (CAD) the Complete Guide - 2D Technical Drawings, D CAD models. This could be through turning, milling, grinding, or all other sorts of manufacturing methods. Okay? In this lecture, I'm going to introduce to you the 2D technical drawing project using on shape will once again use our racecar hub component as our part to practice with. However, best practice is to dimension between two lines. So for auxiliary views, I break the link with the view parent, place it somewhere sensible on the sheet. If you were to date him, all the other holes from the first hole, you would then want to add a position or geometric tolerance in your notes for all holes within that whole table. As some manufacturing processes can work directly from 3D CAD models or directly read a 2D profile in. For example, this triangular shape represents affiliate weld. And because of this, it is a lengthy topic of engineering science to go through. However, I believe this to be the cleaner way to represent the chamfer. So we also then E2 add in some diameter symbols for these 10 and 50. A small window will appear where we have several options to choose. If I select two neighboring cells in the same row, I am able to select this button which evenly distributes the column widths. Then I can do another one down here. When you come to print or export your drawing, the gray squares will not be visible normal, certain other elements of the drawing, which I will highlight throughout the engineering drawing videos. And we do this by clicking on Insert. Below are the reviews written before that update. It's partly the point of drawing to scale. When we look at the PDF, we can see that we have a nice clean technical drawing. And then I also want to add in some center marks and center lines and pitch circle diameter lines. Caution needs to be taken here. So I'm going to place this down here. I needed to scale a logo to be embossed/debossed on parts and wanted an easy scalable sketch. The projection view, then selects a section view. Okay? So I generally use seven millimeter lettering for title, blocks of view titles, five millimeters for some few titles, and 3.5 millimeters for dimensions and notes. Exercise 5.1B - Solution: Hi everyone and welcome to the exercise 5.1 bee video solution. Now I see - most of the tree was always invisible on my screen! And this is a limits tolerance as well. i'll draw a line in my sketch at like 1", then dimension that to whatever i need. 11. I'd suggest you select two characters, which means that you have space for two characters inside the circle. But because we use dimension between two points tool, we didn't automatically get the diameter symbol. We can continue to add views with further clicks. 2d technical drawings are vital to turn computer aided 3D models into a format that a manufacturer can read, interpret, and deliver the physical version of your part. By clicking, we will place our view down. Detailed drawings can be simple, as shown with the rubber seal drawing. I'd send a PDF for machine drawings in parts made for manufacturing processes that do not take in line. Like so. So it's going to place the view down about there. We can tell that this is our three-part model. So it's a bit fiddly sometimes. We have six holes here which are made using the extrusion removed tool in the 3D modelling workbench. Inserting Geometric Tolerances: Geometric tolerancing is an important part of 2D engineering technical drawings. This is not for commercial use and your projects will be visible to the public, but it's really a useful plan to be able to learn how to use on shape. Clicking these two lines finds the point at which each line would intersect. Then I can select the callout tall. Use the dialog to find the document and DWT you are looking for: Select the document that contains the DWT file; then select the file itself. So it's a concentrated diameter, 0.1 and a datum of a. Double-clicking on ourselves selects the cell and allows you to start typing text again. Our next two tools help us create dashed lines, which we can use for various things. And in the third definition, there are more than one type of threat definitions, imperial and metric of the most common. Leave these as default personally. Note that when we click away from the box, the numbers change. 19. 3d CAD models should always be modeled as one-to-one scale. And there we go. This can be useful if the view is typical for a number of features where you can write typical to P OSN or just to pos n would be okay. Welcome to the Onshape forum! I can put in these ones as well. Assembly drawings contrast, however, in that they specify how more than one component comes together to form an assembly. I always use millimeters for units, but this will depend on what you and supplies you intend to send these drawings to. The start of an assembly drawing. So I'm going to put in three. We get that same window by clicking this icon. And then you can see that we are left with just the geometry that was not between these two lines. It is currently set to 10 millimeters. We can also add a closed shape around our dimension, signifying an inspection dimension. Whether we wanted to add a title row and a header row. An alternative way in which you can dimension this radii is by using the radius tool and then annotating the note by saying five pos n aqueous based on a diameter of 125 millimeters PCD. The finish of the component. Actually is student lines to this one here. Examples of a common use of these combinations of line weights and styles are as defined in this table. When you select more than one cell, we get a different menu appear, giving up some table functions. In this video, we'll be looking at the basics of geometric tolerancing by using these two tools. Think of it like this. If we write this in the box to pos n, where pos n is internationally recognized short form for position. So you really want to start off with the intended view convention. So I'll add there to there. So just wait for it to generate. Imagine we accidentally dragged up dimension value out to here. Next, we click on the green tech. So I'll add this one in just like that. maybe esoteric till you get it and then the word I use is elegant. But if not, there are step files attached in the resource area and you can create the technical drawings for these exercises from those models. The one millimeter radius, once again, you'll have no decimal places. And these four holes I created with the whole tool in a 3D modeling workbench. So I'll add in revision one. So we're being prompted to set the origin to datum all of the holes from. Many European countries use a comma to denote a decimal separator. However, we'll put in some extra text. With regard to the sketch shown in the GIF, there were 2 FIX constraints that I had to delete, on top of deleting 2 of the 3 dimensions, which left me 1 dimension that I was able to change and scale up the sketch. Then you have translucent, which looks a bit like glass. You need to select the location of the cut line. In this lecture, we're going to look at how we can gain access to and shape to start actually using it. So let's start at this far end. Worked very quickly and easily for me. A final left mouse button click will set your view. And you could do the same for this radius down here. And you can tell which has been used by the symbol used in the title block. Property:Documentation name or Nickname = Title block: Drawn, Name, Property: Created date = Title block: Drawn, Date, Property: Part Number = Title block: DWG No, Property: Description = Title block: Title, Sheet number - Automatically displayed and updated in the title block, Total number of sheets - Automatically displayed and updated in the title block. Select the dowloaded file under Current Documents tab to replace the current format. If you make a mistake, you can select this button here and select Show excluded. I'll do the same for the tolerance precision as well. You have the ability to edit the fields in the title block as you normally would: drag, copy, and paste. On shape is an amazing cat package crammed full of useful features, has intelligent file storage and is extremely intuitive to actually use. We're then able to neatly positioned this datum by selecting the datum and then move it along the extension line when holding the left mouse button on the blue circle. We get different options depending on the file format we select. So I need to put it in a center line as well. 30. Unfortunately, all of our diameters are pretty similar and it won't be obvious writing a statement to say that this time to hear is the second feature we are trying to refer to. We hope to see youtake part, enjoy this class and post your projects! As an example, I could select the top left and bottom right corners of my image. When it is possible to keep a section view aligned with a section cut, it is best to do so. We can make these center lines in an alternative way by using our second tool. However, if we select one of these holes, you can see that they do highlight in brown as these will create it in the whole tool in the 3D modeling workbench. Selecting this option will bring up a menu. And that is all dimensions we need for this part. We will have a slight deviation. If you want a challenge, why not try and model the components from the technical drawing and the resource section and then replicate the drawing from your model. This is something that you need to specify. To start off with, our dimension tool has a drop-down menu allowing us to select different types of dimensions. So we can continue adding some of these in. In this section. Two brilliant. The 60 has just 0 decimal places. We then have a number in this larger box here. And then I'm going to use one-to-one scale. Setting up an Onshape Account: Hi everyone. You can move more than one component at once. So I think there should be, okay, I have enough space of dimensions. So I'm gonna put this here. I always delete this for isometric views and replace it with do not scale. Once we around to the note tool menu, we can re-edit what we have done by double-clicking on the text box. So there we go. All by forcing the view to a different scale. So there we go. And this should be obvious as to the location of where this is. So we can add length of trailing zeros is important. When we've created a closed profile, we can left-click on the tick. There is some milling, so it's open to the material removal. This really is a great function in on shape. And there we go. We have the blue filled circles, which we can manipulate by holding the left mouse button and dragging. Another instance where this tool is useful is if you want to dimension geometry that is not aligned to the horizontal or vertical axis. And that radius is all the way round, so it is just a single radius. And once we have clicked with the left mouse button, will then be asked to place a second cut line. We save a named view by clicking on the down arrow of the camera and render options button and select named views. Check out the, Please submit support tickets for bugs but you can request improvements in the. And we can hold the control key down, hold the middle mouse button down, and move the cursor around the page to pan the part around. So if unchecked were to add anymore and this is where you could look to see them. Just like that. Yet our title block may say otherwise. Changing between first, third angle projection after you've created views and dimension them though, may not always update correctly. If you drew your shape incorrectly, you can switch to the spline point option and add points to your spline Line. If I select the whole tool and tried to select this whole, I cannot. Then we can add the concentrates, the geometric tolerance to the dimension by selecting this tool where we get a menu popup, we can select the relevant symbol from this box. Exercise 5.1A - Solution: Hi everyone and welcome to the exercise 5.1, a video solution. So it's 20. These can be done by pressing these buttons. At the top of this pain, we have a button that allows us to insert a new sheet to our drawing for if we cannot fit all the views we need on just one sheet. Thank you - please use the Feedback button to provide additional details. We have drop-down boxes for symbols, textboxes for our dimensions, radio buttons for flags and other options in the top-left, as well as the all round button. So I put that down. We can place that down somewhere around here. We can do that by selecting a section aligned to the horizontal orientation. If something can be misinterpreted on a drawing, it's wrong. Then I'm going to put in exercise 5.1 beat. 2. This is not different for engineering technical drawings, the international standard, BS 8888, technical product documentation and specification acts as the primary hub for technical specifications in the form of engineering technical drawings. Perhaps I can put it in there and then bring this 72 out a bit more. So I should put in dimension over here. I selected two lines here and here, which means the offset amount is from here to here. I can't be sure of the motor for a 20 millimeter border, other than allowing for some clarinets, four hole punches to view the drawings in a flip book. But then this one is also 0.1 and we have a tolerance and they usually use the limit method. Finally, we can add balloon references. So now add some dimensions in. I think further specification to a feature or a component and include the following. And then finally in this bottom box, I'll put in a couple of spaces, decimal point, and then a double X, which is symbolizing two decimal places.
