What is going on here? https://youtu.be/KD4p2mLdCEA
Move the group ... and it doesn't re-draw properly. Each time I move it, one more piece disappears and part of it's characteristics (usually thickness/distance) will transfer to something that remains.
I've not used 3D much, perhaps there's a bit of 2D habits that shouldn't be done in 3D?
For the wheel hub, I started with a 5.5" circle in one of the first three View Menu options.
Add in the inner two circles, then place a 4.75 pentagon on the same center as the circles so that I can place 5 .5" circles in the positions of what will become the lugs.
After tilting the view slightly to get a 3D perspective and use the Push / Pull tool to make the large circle .7" thick, and then each of the lugs to be 1" and the center two circles that form the hub get pulled to 2".
Create a second set of two circles to form a hub for the backside of the lug plate and use the tool to pull that as well.
Change to a side view so I can place the just created shape on the other side.
Select all of it, make a group and then move it. The result is not what was started with.
Using the Undo results in moving the thing back, but not in restoring the components.
Also, what is with the left over shapes after using Push / Pull? You move something and there's a left over piece that stays. But if you grab and move that it will move the 3D shape as well. If you delete the left over shape, then it gets weird when moving things in general.
