Thankyou all very much for your suggestions, and for the speed of the response. The problem was nothing to do with a modifier because I have not started to alter the site model but there may have been another polygon floating around that affected the computation. I particularly appreciate Peter Cipes pointing out tools that can assist. It often seems that there is too much in VW for one brain (or one set of manuals) to record) I have finally created a model by moving all the contours to a completely clean drawing and so have avoided redrawing them all, which I was dreading.

What is a Miscellaneous Error (20,2)? I am trying to create a contour model, following the procedure in the manual and as recommended in previous posts. I use the Bezier tool to draw the contour lines, bottom to top; I convert them to polygons and then go through the Survey Input procedure to convert to 2D polygons to 3D contours. Then I try to create a site model and get the message: A miscellaneous error has occurred. (20,2) No overlapping contours, no doubling back; all layers at 1: 100 and each 3D contour has a z value in the OIP when converted. What am I doing wrong? The error message gives no guidance at all and the online help appears not to list errors. Any ideas? Martin Dickie Dickie Architects VW 11.5 on a G4 PowerBook

I have the same problem on a G4 running 11.5 on System 10.3.4 and there is definitely no other machine on my network running the software. It allows three retries which allows current files to be saved but is still very frustrating. My local support tells me that he can do nothing since the problem is intermittent. On his advice I upgraded the OS to 10.3.9 but that has done nothing to cure it. I am replying to Miriam's post so that Nemetschek know that is is a widely ocurring problem and, hopefully, can investigate.
