Solved by b_a_osman. Unfortunately, AutoCAD does not let me do this.If I try to do this, AutoCAD lets me snap my line's first point to one of the points at different elevation, but as I try to drag the end point to the 2nd point at a higher elevation, I seem to be constrained to the elevation of the 1st point.So it's like I can only extend my line on the elevation of the first point.I think it's a UCS problem, but I'm not gonna change my UCS everytime I try to do this type of drawing.Anyone has an idea? u cannot escape this .. u'll need to change the ucs whenever u need to draw an arc or a pline in 3d .. Leave the game running and showing the line. In 2D to approximate the surface we simply had to draw lines between each purple dot. A duration of zero shows the line … ... or disable keyframes Next Draw an animation curve. Link object accessor function or attribute for generating a custom 3d object to render as graph links. ...
