extrude/ remove feature

christopher_bosworth

i am using onshape to create a phone case, i have a sketch on top of the frame for the phone to cut out a spot for the power button but i cant seem to get the extrude/ remove to work. when i use it it just deletes my sketch and leaves me with the frame of the case when what i want it to do is cut the hole in the case where the sketch was. the error i get is extrude 2 did not regenerate properly and no merge scope selected.

You can make this work be either selecting the merge scope field and then selecting the case, or just select "Merge with all" if you're feeling lazy:

Hi could you share the link to your model so I could have a look?  Then I could show you how I would go about it.

For an extrude to remove from something, it needs to know what that something is.  That is what the merge scope is for.  Make sure you have the part(s) you want to get the removal selected in the merge scope field.

And it is most likely not deleting the sketch you are using, just setting the visibility state to hidden.  If you find the sketch in the feature list and hover over it, there is an eye which indicates whether the sketch is visible or invisible.
