I will try to explain this...
before either upgrading Mac os or AC 18, I could drag along an axis and reference the center node of a wall or line that the new element does not touch, but, lately I have to hover over the existing element and get the node or special snap point to appear and only then can I use that point or node/special snap point to stop the other element on the referenced node. If anyone understands what I am trying to explain, what has changed and why?
Imac,10.10.1, AC 18
Thanks
