   Hi everyone, I have a question about AutoCAD 2013: is it possible to assign a variable (for example to a line) instead a numerical value? So I'll be able to change it whenever I want without extend or trim lines.Thank you

	What is a "numerical value" of a line? Do you mean its length, or XData record, or some kind of a label? For length, you can use AutoCAD parametric functions (see the Parametric ribbon).

	I'm not quite sure I understand exactly what you mean, either, but is something like LENGTHEN with the Total option what you want to do? You could build a function that would feed a variable into that for the total length, and leave the User to select Lines they want to be that length: (command "_.lengthen" "_total" YourVariableValue)

	If you did this, how would the changed variable know which end of the line to change, or if both?

	With parametric constraints AutoCAD knows which direction a line was drawn so it will know which end to modify. In this case however what the OP is calling a variable would actually involve changing a constant (line length). Dave.

Lengthen with the Total option just moves the end nearer where you pick the object, leaving the other end in place. [I don't have a new-enough version to have constraints, which may affect that.] The variable would only be a number representing the desired length, though we still haven't heard from the OP about whether that's what is meant in their question.
