New User with some comments

My Name is Jim Buskirk. I have been a user of several brands of CAD software since the late 1970s.  Recently, the CAD system I'd been using for years on my PC died after a Microsoft Windows 11 upgrade.  So I started to look for an inexpensive (free) replacement.  I stumbled on Libre CAD and thought WOW!  I already use and love Libre Office; this will be great.  
After downloading and installing, I opened it up and very quickly came to the realization we are in the very early stages of this project.  So here is some feedback to help you add functionality.
Line function:
Users need to be able to draw lines of specified length and angle.
Users need to be able to copy lines parallel at a specified distance
Drawing sheet/Page formatting:
Went to the manual, it mentions the PAGE tab, no clue what it looks like, where it is how to find it how to open it.
Folks, I want this Libre CAD to turn out as good as Libre Office.

Welcome Jim!

It sonds like you have accidentally installed LibreCAD 3, which is indeed lacking a lot of features beacause it is far from production state.

If you follow the download links on our homepage https://librecad.org/ you will find a LibreCAD 2 Release which has all the features you mentioned.
The latest stable release is here: https://github.com/LibreCAD/LibreCAD/releases/tag/2.2.1.1_rc-latest

More information can be found in our online manual or wiki and of course here in the forum.

Btw I recommend to change your user name into something different than the email address.
Otherwise you may get a rising amount of spam.
