I'm a new-ish user, converting from MicroStation as well, LibreCAD has no costs associated with it.
Where's the best place to ask a technical question? I notice a lot of users post questions in the Introduce Yourself forum, which isn't really the point of the forum, is it?!
My background is (as stated) MicroStation and I've AutoCadded a teeny bit. I'm not too old, either!
We are not so strict about posting in wrong sub forum, except for cross posting same question in multiple sub forums.
Usually, question about using LibreCAD are best placed in the user sub forum When in doubt, each sub forum has a little description under it's title, but I'm afraid that it is invisible in some browsers
