tittle is funny, but my question is, does the size that i draw in autocad matter? or can i scale it before i print it to the size i really want it? please help!
If it matters, how can i decide the sizes in autocad?
Punch shape - now that makes a bit of sense - you should have included that information in your original post.
Your punch is not at all what I envisioned when you asked how to draw a specific brand of sun-glasses.
Any CAM program should be fine for this simple punch shape.
Who is going to do the actual machining for you?
Do you have CNC machine?
Assuming you don't have this machine (as you don't seem to know much about programming it) just turn the file over to the shop that is doing your part. It will take them about 5-10 minutes to create the g-code (unless you have left out other important information).
