Surface

Hi guys
How can i merge or join several surfaces together?
and how can i cut through a surface?

If the faces share at least one adjacent edge, you can merge Surface 2 to Surface 1 by selecting the Add option instead of New. You can't cut through a surface, but you can Trim it (with sketches and other surfaces) and selectively hide/delete the resulting surfaces.

@Anwar_E you would be better off building your building using solids. If you really need a surface (?) you can delete the faces you don't need at the end using Delete Face.

You can use my boolean feature ( https://cad.onshape.com/documents/84d939daceef6a928b8abcba )

I like your opBoolean feature, seems like OS's boolean should work with surfaces (sheets). Have you thought about writing a true surface trim feature that allows you to pick the sheets to delete/keep? You're splitting them nicely. Just wish I could define the ones I want to keep using one feature script.

Currently it's confusing to have to split and delete sheets for trimming. It'd be nicer to have a true surface trim feature script that would allow you pick targets & tools, and then pick the sheets you want to keep. Hoping there's a selection that'll return where on a surface you picked, and with that, the user can pick the sheet bodies they want to keep.

Maybe using vertices?
