mirroring a sketch and inverting the planes that would extrude

richard_theodor

I have this sketch:

as one can see from the sketch the inner rectangle and the two holes will be extruded. My original plan was to mirror on the construction line on the very right side of the sketch, but the result is not what I was hoping for (this is a super simple sketch, I know, I could easily draw both sides, but I want to understand what I am missing here). After mirror it looks like this:


where I actually wanted to achieve this:

First, that is not a super simple sketch - I would break that part down into simpler steps to make it more robust. Second, ignore the fact that the areas are shaded - that just indicates enclosed areas that can be extruded.

If all parts of your sketch are gray, then in this particular case, the program is smart enough to know what to extrude.

So if you are inside of the sketch, that is, if you're editing the sketch, and from within that sketch you go directly to extrude, it'll take care of extruding the part you want without your doing anything (again - in this case).

If you are outside of editing the sketch and you select extrude, then all you need to do is select the particular part of the sketch that you want to extrude.
