Working in project with Plant 3D and my mouse is very jerky when I move. However when I hold down the shift key to disable ortho, the mouse works like it should. The mouse was working great yesterday. Any suggestions?
I have ran into the same issue as well. It seems the selection cycling takes some time to "poll" the objects in the drawing when the mouse cursor moves over them. The Plant 3D objects are much more complex, as opposed to standard 2D cad objects, so there is a delay.
Plant 3D also slows down quite a bit when dynamic input is turned on. I usually only enable dynamic input when placing valves or inline components.
