drawing a line

Hi Guys, the command line will not accept a manual dimension. i get unknown command
i have LC 2.2.0-rc1---what am i doing wrong. tks Ken

What do you mean with manual dimension?
Invoking by command line? Or manual text override?
LibreCAD commands are not always the same as in AutoCAD.

eg. i want to draw a horizontal line 2500mm long.. i start with first point and command line asks specify 2nd point.. then i put 2500 in and all i get is unknown command 2500

2nd point:   @2500,0

I recommend to study the manual.

Hey thanks Dellus-- got it now....
