in the video I try to select the entirety of parts in a downloaded STEP file via Groups, but once I highlight all the parts of the chair, it reverts back to de-selecting them. How can I quickly select all the parts of the chair (+ join them as one object) - so I can move them around in the environment effortlessly?.. I might* need to scale the chair as a whole, but I more-so just need to rotate, duplicate and move them around in the workspace? Why is it like pulling teeth to try & execute simple tasks like this in the current version?
