For me, it was a kind of 2 step-process:
1/ learn CAD drafting
2/ learn how to CAD draft based on LibreCAD tools and logic
3/ since you run a business, have a deep look at key shortcuts (and SPACE validation) once you get more familiar with the tools to increase productivity -> one hand on keyboard and one hand on mouse as much as you can (check AutoCAD or Draftsight tutorial) even if the capabilities are different.
1/ Numerous ways to do the same drafts depending on which tools and combination of tools you know and you are comfortable with. Exemple: you can draw a lot of baselines using Parallel to
command and then trim them (much similar to pencil drafting) or you can use relative coordinate and lines. Same result, different approach, different preparation, not suitable for all drawings.
I advise to look at video tutorials for LibreCAD or Draftsight (even if LibreCAD capabilities are different). You can see experienced people's process and get a feeling for their logic until you build yours.
2/ Have a look to user manuals to get a feeling of capability. Then look at LibreCAD only video tutorials. for many commands you can select a line or another object and perform a command OR launch a command and select the object(s).
At the very begining, I train doing several times the same simple draft with different ways:
- much computation for coordinate and relative coordinate lines
- much crossing baseline trimmed in the end
- other mix of commands.
Good luck !
