Postby rahmanshaber » Tue Feb 18, 2020 5:06 am

Hi i am from fusion 360 user. There i can extrude multipal part from a single sketch. But in freecad i can't able to to that.
the issue is in extrude/pad i can't select the part of the sketch that i want to extrude. it always extrude what it likes, i mean select the sketch it self.

You can drag/drop them over the text editing area or use "Attachments" tab under the "Submit" button.

On your main question - this is just the way FreeCAD is designed to act at the moment. You can draw everything in one sketch and then use "Link external geometry" in another sketch to import only the things that you need for that specific feature.

but think about it, there will be so many sketch. And where is the "Link external geometry" thing? any guide for it?
