designerstuart Posted June 2, 2011 Share Posted June 2, 2011 did you mean to attach an image? Quote Link to comment Share on other sites More sharing options...

CyberAngel Posted June 2, 2011 Share Posted June 2, 2011 Is it a line or is it an arc? Does it have to go through all four points? Must it be a sphere or can it be some other type of curve? We need more. A picture would help, as designerstuart suggested. Quote Link to comment Share on other sites More sharing options...
SLW210 Posted June 2, 2011 Share Posted June 2, 2011 A spherical 4 sided figure? What? You have not heard of the spherical 4-sided figure? That makes 2 of us. Quote Link to comment Share on other sites More sharing options...
Jack_O'neill Posted June 2, 2011 Share Posted June 2, 2011 What? You have not heard of the spherical 4-sided figure? That makes 2 of us. Pyramid with rounded corners maybe? Quote Link to comment Share on other sites More sharing options...
Jacko93 Posted June 6, 2011 Share Posted June 6, 2011 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.

Jacko93 Posted June 8, 2011 Share Posted June 8, 2011 Do you mean like a cube with bevelled faces? I'm confused, really confused. Quote Link to comment Share on other sites More sharing options...
CyberAngel Posted June 8, 2011 Share Posted June 8, 2011 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. Quote Link to comment Share on other sites More sharing options...
Bill Tillman Posted June 8, 2011 Share Posted June 8, 2011 This is why they make drawings...to communicate ideas to others. Upload something otherwise all of us will be guessing at what you want. Quote Link to comment Share on other sites More sharing options...

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.
