Top-Down Design [webinar]  

Great vid!!! Min 25:30 you sold yourself short. It would've been super informative how you did the phone case. Min 26: Great questions. Helped us reason with you and learn the info.

@26:11, you can save a virtual part as a "copy". And then go ahead and make changes to the copy rather than the part. This way you can use the part in different project without effecting your original assembly.

I use SelfCAD and I love it

Right.

Other people need to work on your designs as well. It should be easy to follow what you have done.

very helpfull. thank you
