I need to draw a line and when drag cursor for 'second point' input , I wish display length of line (in real-time) near cursor (like yellow tooltip in polar mode). I have used grread,grdraw and one little text entity to display in real-time line length. The problem is that grread function does not recognize ortho, snap e osnap modes... the crosshair is completely free. someone have one (good) idea ? thanks :-)
