ellipse in motion program

Can you redefine your axes? If you were to scale them differently, then draw a circle, your result would be an ellipse.

Alternately, if you can generate a list of points along your elliptical path, you could use a SPLINE move and simply command the tool tip to move through all of the points.

We're trying to think of if there's a better way...theoretically, drawing a circle in 3D space, projecting it into 2D space to get an ellipse, and then performing an axis transformation to rotate it would lead to your tool tip truly being commanded along an ellipse, but I don't feel it's particularly elegant.

Hello AAnikstein,

Many thanks for your kindly reply.
Yes, I know the desired ellipse can be got from a projected translated spacial circle.
Do you mean PPMAC cannot draw ellipse directly? I want to draw it with a robot .
