Offsetting a curve with librecad

I tried to offset a curve but the command seems to work only with straight lines. So I first exploded the curve (it was a spline), and then I selected the segment of it, and then when I said offset , it worked for a certain distance which I couldn't specify how much, but I repeated the command several times to get many offset lines and then deleted the intermediate ones.
I guess the offsetting of curves should be added to the program in its next release, if possible.

Set the distance for offset in the Tool Options bar above the drawing area. It changes the content according to the used command.
