Works fine! Whith that no need to make a Ctrl + z for erase a line !
And good result as we can see the result also on the Botom bar :)

Is it normal than a line is drawn and disapears at the end? I suppose yes :)

Have you plan the same for Angle between 3 points in the space?

Ps What is the language used?

Pss For the translation : is not possible to use something yet existant in the ui folder?
Else now we are obliged to translate in the Command Folder too !
(not very practical:)

Hi Richard,

Maybe, I should have mentioned that the script is for evaluating distance beetween two points, not for making object at all.

>>For example: 23@<15 like in AutoCad or X-Y-Z coordinates such as 2,5,0

I hope you know that you can type this in Point controls at the bottom of the screen when command requires you to enter a specific point.
e.g.
5,15
r5,15 or @5,15
5 (distance constraint)
<15 (angle constraint)
5<15 (absolute polar coordinate)
r5<15 (relative ones)

// boolean group is called with shortcut B=Booleans.js

// something is missing here...

while ( 1 )
{
        var key = WHICH_OBJECT?.event.keyCode;

        if ( typeof( key ) == 'number' )
                break;
}

var keychar = String.fromCharCode( key ).toLowerCase();

// bu ->BooleanUnion
if      ( keychar == 'u' )
        moi.command.execCommand( 'BooleanUnion' );
// bd ->BooleanDifference 
else if ( keychar == 'd' )
        moi.command.execCommand( 'BooleanDifference' );
// bi ->BooleanIntersection 
else if ( keychar == 'i' )
        moi.command.execCommand( 'BooleanIntersection' );

Just a problem of design !
"Yellow words" are unreadible over white page! :)
Maybe orange?
