In version 6023 new method RemoveZeroAreaTriangles of gTriangles was added.
Remove all triangles in the collection that their
return the number of items that removed from the collection.
Also new method Area was added for gTriagle and gTriangles collection objects.
Example
It gets the triangles of a vdPolyface that their area is different from zero. gPoints verts = new gPoints();verts.Add(new gPoint(0, 0, 0)); verts.Add(new gPoint(1, 0, 0)); verts.Add(new gPoint(1, 1, 0)); verts.Add(new gPoint(0, 1, 0)); // face 1 from 4 different points
verts.Add(new gPoint(1, 0, 0)); verts.Add(new gPoint(1, 2, 0)); verts.Add(new gPoint(2, 2, 0)); verts.Add(new gPoint(2, 2, 0)); // face 2 from 3 different points
Int32Array fl = new Int32Array();
fl.AddItem(1); fl.AddItem(2); fl.AddItem(3); fl.AddItem(4); fl.AddItem(-1); //face 1
fl.AddItem(5); fl.AddItem(6); fl.AddItem(7); fl.AddItem(8); fl.AddItem(-1); //face 2
vdPolyface polyf = new vdPolyface(doc, verts, fl);
doc.Model.Entities.AddItem(polyf);
polyf.Update();
polyf.Invalidate();
gTriangles gtr = polyf.GetTriangles(); // contains 4 triangles 2 for each face, but one ofe them has zero area
int ret = gtr.RemoveZeroAreaTriangles(); // will return 1, the number of the triangle removed and gTriangles will have 3 traingles left
