Greeeting all from new user

Greetings!

Hooray, I did it, I started to learn LibreCAD!

So, as I new with LibreCAD and quite new to engineering CADs before I ask a lot of stupid questions, guide me, please :)

Is there any document/article something about @LibrteCAD best practices"? I. e. how to arrange layouts, use miscellaneous drawing tools and so on in right way?

Welcome.

Step back one page to https://forum.librecad.org/ and click on the link at the top of the page to take you to the wiki where there are some introductory tutorials. You might like to watch some video tutorials too.

The LibreCAD User Manual is very good and, with the exception of the Reference section after Fundamentals, it is very readable.
