How it works
Adding triangles to a 3D object
A 3D object is made up of triangles, and triangles are made up of three
points. So when you make a triangle on a 3D object you make -- or attach to -- three points. Normally you will be attaching to some points already on the 3D
object and creating some new points.
This is the hardest part of making 3D objects, so take a little time to learn
how to do it.
To add a triangle to a 3D object in the 3D object editor,
If this is your first time adding a triangle, make sure the points are big enough to move easily. To change the point size, click the arrow button to open the options panel, then change the number labeled Point size.
Click Add triangles mode .
If the triangle you made didn't connect the way you wanted and you are still in the middle of making it, finish the triangle anyway, then click the Undo button to remove it.
If you only find out later that a point you thought was connected really wasn't, delete the triangle and make another one with the proper connections. A quick way to find out if all the points on a new triangle are connected is to quickly drag each one of them around to see if a point is orphaned.
