While trying to import the attached SKP file from 3d warehouse X12 quit, no message. So after the third attempt, I get this message from Windows 10 when I start Chief. (See attached)   Not sure it is a Chief problem or a windows problem. Anyone work through a similar issue?   https://docs.microsoft.com/en-us/windows/win32/win7appqual/fault-tolerant-heap Floor Polisher.skp
