I can´t do a curve with this command… I used this command before but now is not working I only can do a straight line instead to do a curve with a free form.
Maybe you set the degree to 1 accidentally? Degree 1 will make polylines.
If you want to make free-form curves, set the degree to at least 2, preferably 3 (which is the default value).
Thank you very much, that was the problem.
