Newbie using Atom3D 2019. I'm completely mystified about how to move multiple elements in a 2D sketch. I've seen tutorials where you simply select multiple elements, two circles for example, and then click on one and they both move together. That doesn't work for me. In the image below I drew two "objects." Before adding the dimensions if I selected all the elements in one of the objects and tried to drag it somewhere it would simply move a single element of the object thus changing the object. Yet when I added the dimension on the one on the left I am able to move the entire object up and down. Likewise the object on the right couldn't be dragged anywhere as a whole. And when I added the dimension it's being constrained by something and I don't know what. I can't change the 14 to anything else. These objects are extruded fine too so they seem to be properly closed objects. What am I missing?
