How do I create a lid for my box? The lid should match the edge of the box

björn_teichmann

Hello, I am an ONSHAPE beginner. I have created a box and afterwards I would like to create a lid for it.

However, my box has a chamfer to the inside.

For the lid I would have to create a negative of the upper edge. Is there a quick solution to create the counterpart of a shape, i.e. a matching lid?

Here is the link to my box with the lid experiment: https://cad.onshape.com/documents/22f0a0bf1c8685cc03442ec5/w/ea3987b4b99e9e0d7aeaf881/e/362e5bf83e11edaa8ee24df7?renderMode=0&uiState=65c501002d7ee262fc306cc0

It's better to make the lid earlier on in the design, before you make all the holes on the box. Also, you don't need the 45 degree chamfer you had. The 10 degree angle already on the sides of the box is enough to guide the lid into place.
