Trying to draw wood cores for skis/snowboards, and need help please.

Hi all, I am going through the tutorials and manual and am not seeing anything applicable for my use. I have a xyz router table with mach3, first I need to draw the top view in xy,  with drawing large arcs from 10 meters to 15 meters radius with a cord of about 150cm. Secondly, I would like to blend 2 arcs, first 15m, second 12m, and blend them in the middle, thus a dual radius edge ski, if possible. I am also trying to draw the xz (side view) and input dimensions for the Z as a ski is thinner at the ends (3mm) and thicker in the middle (12mm). Any help would be greatly appreciated, Robert

Hi all, This is what I found from Turbo2ltr, 1) draw the z thickness in xy, select and convert to polyline and join 2)rt click new polyline, draw/surface/extrude 3)input extrusion height for max 4)input extrusion steps 5)rotate for view 6) transformation matrix to rotate 90 deg around x axis 7) this leaves upper surface a at 0, I will give it a try and see, Thanks, Robert
