how can i draw this red line in autocad, its an arc from point 1 to point 3 in spherical 4 side segment? point 1 to point 2 to point 3 to point 4 closing the segment at point 1 and point 4 (fused)

I think that Spline could be the answer, set out your four points, then use the spline to draw round them, then delete your points. Difficult to know exactly what it is that your looking for without a picture though.

Spline would give you a non-uniform arced line though. I hope this helps.

a sperical 4 sided figure, not solid..like when you cut a four sided layer out of a ball

Do you mean like a cube with bevelled faces?

I'm confused, really confused.

OP may mean a spheroid section, i.e. the intersection of a plane and a sphere. Maybe there's a four-sided frame around the intersection, which is causing the confusion. A picture really would help, man.

This is why they make drawings...to communicate ideas to others. Upload something otherwise all of us will be guessing at what you want.

An intersection of a plane and sphere would only have 3 sides or surfaces wouldn't it? Front, back and edge...like a coin, for instance. Assuming of course, the plane had thickness.
