9 Practice Exercises for Onshape 3D CAD

Beginner Series

Hi there! I hope you found the 5 videos from the Beginner Tutorial series about Onshape helpful. Maybe you just watched them, or even followed along and built the model yourself. Regardless, I recommend getting some practice to test your understanding of the content. This is what these practice exercises are all about! In case you need to review tutorials 1 through 5 videos again, you can access them here: http://www.cadsessions.com/onshape -tutorials/

How This Works We’re going to continue building on the 3D model we used in the tutorials. I’ll be providing a direct link to the model so we can start from the exact same starting point. Each step has a target task, along with a picture of what the end result looks like. Your job is to add the feature in Onshape on your end. To check if the changes you made are correct,  Visually compare your model to the main picture of that step, and  Use a tool built into Onshape to tell if your model is geometrically correct. This is easier than it sounds, I’ll explain this in a minute.

Open The Model Use the link below to access and open the Part in Onshape. You can view it and rotate it without logging in to Onshape, but to edit it, you’ll have to login. If you haven’t already created a free Onshape account, you can do so now. Access the model here: http://www.cadsessions.com/practicemodel1 The workspace length units are set to inches. Do not change this if you want to be able to check your results after each step. So let’s get started!

Step 2 (continued)

Tips & How To 1. On left side of the screen, below the feature tree, click on “Part 1”. The part will highlight. 2. A small ”Display Mass Properties” icon will appear on the bottom right of the browser window.

3. Click on it. A new dialog will open, showing the Mass of the part displayed in grams, and the Volume and Surface Area displayed in units of inches since that is our selected length unit. Now look below them, and you’ll see the Center of Mass, which is a point in our workspace defined by an X, Y and Z value. 4. I won’t go into what the Center of Mass means exactly, but for any change we make in our model, this value will change, and we’ll be able to use these values to check if the changes you made are correct.

Step 7 (continued)

Tips & How To Sketch 1. Start a sketch on the main right face. 2. We need to find and indicate the center of the pin so that we can dimension off of it. However, Onshape doesn’t recognize the center of the pin on this sketch plane, so we need to make use of a very useful feature next. 3. Select the “Use (Project/Convert)” button. This will let you use, or project feature outlines onto your sketches. Sketch - 4.

4. With the tool activated, select the pin’s outline. This will instantly recreate the pin’s outline and project it onto our sketch plane. 5. Now you can create a point in the center of the pin, and use that to create your centerline. 6. Finally place your circles, set their size with the dimension tool and then set their distances from the center point. 7. Accept the Sketch. Extrude 1. Extrude-Remove 2. Select the 2 circles, set the end condition to blind and set the depth. 3. Check that the Preview looks right and accept using the green check button.

Step 9 (continued)

Tips & How To Sketch 1. Start a sketch on the front face (or any other face you prefer). Select the “Text” sketch button. The cursor will change to a cross. Click and drag the cursor to set the box in which you want your text to appear. A text input box will appear where you can type your text and change the font. 2. After you accept, and the text has appeared in the sketch, a vertical line appears running through the center of the text box. You can use this to quickly center the text box horizontally: 3. To do so, first, add a sketch “Point” in the center of that vertical line. 4. Create a vertical centerline at the center of the part. 5. Finally, click and drag the newly created sketch point, and the whole text box should drag with it. Drag it over the part’s centerline, and release it when the line highlights. 6. Once you’re done, accept the sketch. Extrude Select Extrude, and choose between Add OR Remove , select your text for the input, set the depth, and wala!, you’ve personalized your part. Power Tips - How to make edits to the text and text box  To change the text or font, Right-mouse-click (RMB) on the sketched box, then select “Edit Text”  To resize the text,  Use the Dimension tool to set the size of the enclosing rectangle, or  Delete and recreate the sketched text box  To move the textbox,  Click and drag on one of the rectangle’s blue corners or sides, or  Use the Dimension tool to set the distance between the textbox and some other feature  RMB on the sides or corner of the text box, select “Transform Sketch Entities” and use the manipulator that appears to achieve various transformations.

Thank you! Well it looks like you made it to the finish line! A BIG CONGRATULATIONS! I’ve put a lot of work into this guide, and want to make it the best possible, so your opinion is vital. If you have a moment, please let me know what you thought about this guide or how it has helped you. So, you practiced customizing a 3D model with some of the fundamental functions in Onshape and by now, you have a good grasp of the general workflow in 3D part modeling, which is a really important skill to have when starting to create any 3D model. One thing to remember is that just like with other things in life, there are multiple ways of achieving the same result. When creating your models, there are bad ways, good ways, and great ways of creating features. Simpler is usually better, but there is almost always more than one way to get something done. With that said, thank you for working through these practice exercises and giving it your all! If you'd like to share this guide with others, please refer them to w...
