In response to a comment from a past Coating/Plating Parts blog article, here is a simple technique for removing a few thousands of an inch from a finished part to simulate the stripping of a finish. The task is very similar to adding a finish to the part, except in reverse. The tools will be the same as the method Jason shared, only used a bit differently. The tricky thing about stripping the part is ensuring that you leave any non-finished faces, such as reamed or threaded holes, at their final size.
Please read through the steps below and watch the video for step-by-step instructions.
This method will utilize the Move/Copy Body command, the Shell command, and a Combine Subtract command. Beginning with your finished part, utilize the Insert > Features > Move/Copy Body command to copy the finished part to occupy the same space as the original (zero translations, zero rotations). Hide the original body for ease of face selection in the next step, you may even wish to change the color applied to the body of the copied body.
Now start the Insert > Features > Shell command, specify the thickness you wish to remove or “strip”, and choose to remove only the faces that coincide with the non-finished faces, such as threaded holes. What remains will constitute the “finish” on the part. Next you will show the original body again. If you changed the body color of the copy, you will be able to see the shelled copy overshadowing the original part.
The final step is to use the Insert > Features > Combine command to Subtract the shell from the original body. Viola! You now have a stripped part!
