I would hope this is a very simple question to answer. I have a 3D model constining pipes and structures. This was developed by a laser survey. How can I now extract sections from this 3D model? I was hoping it is just a matter of drawing a line (on the plan of this model) where I want the section and then voila - a new section is extracted. I don't want to use SLICE as this removes sections of the model. I have looked at SECTION but can't quite get it to do waht I want. regards PeterH
