Hole in the Floor

famadorian

I understand how I can add a hole by first extruding a box then extruding a removal of an offset, but that sort of makes it necessary to clutter up the master sketch. 

I was trying to be more tidy and do the hole later, preferably in a derived document, but then:

1. there is no hole
2. we can see the walls of the hole protruding through some of the surface of the floor

This is kinda hard to explain for me, so here's an image and Onshape document

Here's the master sketch:

At first, didn't vote you down. Don't know why someone did since it effectively keeps anyone from answering.. There's no such thing as stupid question in this forum and you included descriptive images & link to public doc  

If you wan't to extrude like that and use part of extrude to cut other parts then boolean is the tool for you.

I would do it into master sketch though, it's easier to edit later when they are all in same sketch and it keeps your feature list shorter.

Now that I see the final sketch this makes more sense. I was confused, I didn't know what hole you were looking for. All I saw was a puzzle piece

(BTW Also didn't down vote)
