Any insights or suggestions?

Hello there! I have prior experience using AutoCAD, and I was quite familiar with its command line. Now, I'm attempting to use LibreCAD to draw a building, but I'm encountering difficulties when entering the lengths of lines the way I want. Specifically, I'd like to draw a line from the current point to the right, spanning 43 feet and 9 inches. In AutoCAD, I could achieve this by using a command like: @43'-9<0. However, I've attempted various combinations in LibreCAD, and unfortunately, I keep getting an "Expression Syntax error" no matter how I try it. I'm wondering if this kind of command is possible in LibreCAD. Any insights or suggestions would be greatly appreciated!

Hello,
The process is different from AutoCAD. Length, radius, angle, etc are usually entered via Tool Option.
You should check the manual and/or video tutoriel to ease the learning curve.

Basically the command is not that false, but sadly LibreCAD is not so good with imperial units.
So you can't enter the numbers as you tried.
See https://librecad.readthedocs.io/en/latest/ref/fundamentals.html?relative-1#relative-1 for reference.

But the commands and most input fields accept math expressions, so there is a workaround often suggested here in the forum.
See https://forum.librecad.org/Imperial-Architectural-Dimensions-tp5718163p5718174.html for an example.

No, for input this does not (yet) work in LibreCAD. You have to set units to inches and for input calculate the value to inches, 43 feet and 9 inches then is 525 inches. In the dimension text it is shown correctly as 43'-9". As a workaround you can write in the command line @43*12+9<0.

There is a pull request adressing the issue and it has recently been marked as merged into the development version 2.2.1 alpha, but it doesn't seem to work:https://github.com/LibreCAD/LibreCAD/pull/1178

PR 1178 is to support feet'-inches"-fractional in construction dimensions, not for command line input.
