It lacks the AI features of newer versions, but it makes up for it with raw speed, low hardware requirements, and unmatched extension support.
Always run the 64-bit version of 21.0.0. The 32-bit version (available accidentally on launch day) is severely memory limited. Look for the file name: SketchUpPro-2021-0-0-xxx-x64.exe .
