SolidWorks is a computer aided design (CAD) software used to make virtual 3D models and create drawings. SolidWorks can run simulations, but not as well as other dedicated software packages.
There are many great tutorials for SolidWorks, especially the YouTube videos released by the company. They also have a fantastic support base, and some good blog posts: "SolidWorks Part Modeling: Basic Best Practices" and "SolidWorks Tips for Beginners" (still a good read for experienced users).
Here are some useful SolidWorks tips we've learned:
- When creating a sketch, choose the plane on which that feature will be located
- Always constrain sketches and assemblies
- Think ahead when adding constraints - for example, will the coupler still be in the correct place if the tube gets longer?
- Update the model, even during construction of the rocket! It helps to visualize how one small change can affect the entire rocket, and the extra time spent planning will help the project look more professional.
Solidworks is very useful for creating drawings, which we use to construct the rocket. MIT's 2.007 has a great overview of how to create drawings, and the Olin College of Engineering powerpoint goes into a little more depth on proper dimensioning, and has a useful list of good practices at the end of the slides.
Here are some useful drawing tips we've learned:
- The drawing should include exactly what you need - it needs to include all the dimensions and views in order to make the part, but nothing extra that can clutter the drawing
- Dimension features from one edge (as opposed to hole to hole dimensions) to minimize the error
- Dimension lines should not cross
- Place dimensions on the most useful view
- Isometric views are not usually necessary, but they are often included to visualize the finished part
- If there is multiple of a feature, like four 0.25" holes, dimension one as 4x 0.25"
