Trial use to practice

Where can I actually practice sketchup and make drawings?

Easiest might be to start with the free online version

You can also download SketchUp 2021 and use the 30-day trial period.

Dave, I have sketchup on my computer and I was able at one time to practice making drawings, I went through the tutorial and now I cannot seem to find the practice session? A little help please! Thank you

To which tutorial are you referring? The series at learn.sketchup.com maybe?
