when i draw a sphere on the workspace, half of the screen will be white and above the sphere i drawed。
how can i solve that？
Looks like a graphics card issue to me. What are your system specs?
Version 1.3.1
pc 64 bit win7
Revit 2018
you have the same problem？
What hardware though. I don’t have the issue but I’ve seen other people have similar issues and it’s often been linked to graphics card stuff.
Search the forum and you will see a few examples.
