how to make circlips in autocad
The dimensions of the circlips housing vary according to the size of the circlips to be used. In technical books, there are ring gauge measures, or rather you have to look at the book of machine elements.
If the circlips itself will be 2d drawing with Autocad, we will again see the dimension table in the machine elements book.
There is also video on youtube for drawing with SolidWorks ..
