I've been struggling with an issue for a couple of days now. I have a connector defined by a point on the same plane as the landing surface, but when I attach other assets to the connector, they are 0.00027143 in below the landing surface. I have tried redefining the connector point several different ways to try to get it to come out right, but nothing seems to work. The only way I can tell that it is wrong is to zoom in all the way. Normally this wouldn't be a big deal, but if I drop other assets in on the floor, and then try to snap them to they won't connect at all. This makes laying things out really hard, sometimes it is necessary to drop a part in and then rotate it in order to easily attach it.
I've attached a few pictures so you can see what's going on.
