I have a few more FreeCAD questions.
First off, using geometry has opened a whole new world and now makes more sense. Although I haven't had any "real" designs, I've been tinkering with different concepts using geometry.
Two things that continue confusing me is in the attached two pictures (although this seems like I should have figured out this problem by now on my own).
In 'Design 1' I made a rectangle with a circle, 'padded' it, and the result was a block with a hole. Wanting to make another hole (used a hexagon to distinguish between the two for purposes of discussion) left to right, I clicked the planer face on the right, added a sketch, and added a hexagon (I 'padded' it so it stood out for my question but want it as a hole that goes all the way through).
For whatever reason, I can't make this a hole that goes all the way. FreeCAD 0.16 doesn't have a 'hole' option, but v0.21 does, however, it doesn't seem to make the hexagon a hole. What am I doing wrong?
In 'Design 2', I made a simple circle (the front part that is highlighted), cut it to make it a semi-circle, and padded it. Now, the (what I consider) more difficult question I haven't been able to solve: how do I mess with the padded part (the top curved black part or even the underside curved part)?
If I click on it and 'create a sketch', it gives me an error that it needs a planer face as a support for a sketch.
Things I'd like to do would be: curve/fillet the corners rather than have 90 degrees, and then just adding something to the non-planer (?) face.
