Is there a way to create a surface/sheetbody from an equation of a plane?
#returns a tuple with a list for the normal coefficients (a,b,c) in index 0 and the d coefficient in index 1
self.theLw.WriteLine("The normal is "+str(plane_tuple))
I was able to create a four point surface using vertices but I have not seen anything where you can just use the plane equation as the input/argument. Other options like N-Sided surface, Ruled require guide curves
#can access vertices this way 
coordinates1 = NXOpen.Point3d(temp_tuple,temp_tuple,temp_tuple)
point1 = workPart.Points.CreatePoint(coordinates1) .......
The plane equation describes an infinite plane. It really only gives you the orientation of the plane; to create a sheet body, you would also need to define the boundaries. There is an option to create a datum plane from the plane equation coefficients; you could create curves on such a datum plane to define the sheet body boundaries then use the "bounded plane" command to create the surface.
