This panel is supposed to automatically pop-up, correct? Without it - I can’t change the number of sides of a primitive when I add one, the “remove doubles” threshold, etc. etc. etc. I have no idea what happened, because it used to be there. I posted a screen shot of what I DO have at the moment. So frustrating. I looked everywhere and just can’t seem to figure this out.
wow, like two seconds after I posted this (and 2 hours of trying to figure this thing out), I found the little plus sign at the bottom right of the 3d viewer. Haha. Thanks for reading though if you’ve made it this far.
