When using the wizard to create a Vertical Offset Model (VOM) it directly makes triangles of the points. If you change your linking settings, it can only make new triangles based on the existing ones. If you use the wrong link distance, to short in this case, you end up with way to few triangles. The e points where ignored and get lost, you can not use those points again. You need to redo the whole import process again.
Store the points on a seperate layer
- Allows visual check of the triangle results
- Makes it possible to easily tweak your links as the user can recreate triangles and store them on the dedicated layer.
