Any help files for creating and manipulating geometry.
I have used AutoCad at a job, but don’t have it at home. My intentions are to get familiar and eventually do 3D modeling in order to print.
The videos online are not practical for this platform.
Which videos? Which platform? Your forum profile has conflicting information There is no SketchUp for Web (Free only) 2024 Desktop version.
Modeling of what? To print how?
Have you gone through the tutorials at learn.sketchup.com?
Coming from a CAD background my advice is;
be like Star Trek’s data, remove the CAD chip from your memory banks, purge and then insert the SketchUp chip.
