Ok I know that this has been covered about 300 times. But I figured I would ask any way. Most of my days are spent on Revit 2017 Bim Molding electrical. am having trouble with the program lagging. At times I will click on a pipe to modify it and it may take 5 seconds for it to let me do anything. Im running a Mac book pro mid 2014 i5 8gb of memory. I have windows 8.1 installed on a external SSD PLUS from Sandisk. Can anyone give me some help on how to make Revit run better? Thanks in advances for any help.Im also running the latest version of Parallels
