Project 2D curve to a 3D sphere.

With the freeware utility CADstudio SphereProj you can project any 2D curve (polyline, spline, arc, line) or a group of curves to a spherical 3D surface.

The add-in application SphereProj can be downloaded - like the other CAD Studio's freeware tools - from www.cadstudio.cz/download. Load it with APPLOAD and the run the SphereProj command. After you enter the sphere radius, the command marks a rectangular area that will be projected to the sphere (at 0,0,0). Any curve drawn in this area can be be transferred (projected) to the sphere surface (the horizontal axis of the rectangle will become the "equator" on the sphere, its upper and lower edges will become the north a south "poles"). The 3D projection respects the color of the original 2D curve. You can specify the precision of the conversion - the number of segments that the original curve(s) will be divided to.

If you want to project a text, convert it first to to lines - see the tip 1901. Projection of geometrical entities to an arbitrary 3D surface is described in the tip 7297.
