Help with extrusion

willian_tamagi

Hi folks,

I'm trying to extrude a wall in my project, but this wall should only have the height of another part, I tried to use "up to part" and selected the part but it did not work...
FYI this part is imported.

If someone can help me here is some screenshot of the "problem" and the project link

The main problem is you can't extrude up to a part, if part of the face that you're extruding will intersect with nothing. The wall you're trying to create goes over a hole in the part. If the inside was one big surface, you could successfully extrude up to face, even if there was a hole, but this part has so many inside surfaces, so there's no easy way to do that.

I deleted the faces of the hole in question, and then I extruded the wall first, before cutting away the outside of the part. That seems to work much better. I also added back in the hole that you extruded sideways later in the part. I'm not sure exactly where that needs to be, or what this is all for, but it should give you some ideas.

See if this is what your looking for. I made a 0mm offset face and added a couple of fills to make it contiguous over the sketch to be extruded. Then extrude to part with the surface selected.
