Dieter @ DWorks Posted January 8, 2013 Share Posted January 8, 2013 Hi, I have a large DTM of a couple of streets with multiple lots for buildings. The DTM works fine. I have a file for this DTM and a file for each building. I use referencing to import the DTM into the building file. I have to create elevations, but because the site is so complex, I need to use the DTM in my section viewports. VW always crashes on this. So I need to find a way to convert a copy of the DTM to something else so that I can render my elevations created by section viewports. I can't find a workable solution. I have tried a draped surface, .... Even converting to 3D polygons doesn't work well because of the size of the DTM. I hope others have a solution for this. Quote Link to comment
Bryan G. Posted January 8, 2013 Share Posted January 8, 2013 How about a camera view? Quote Link to comment
Bryan G. Posted January 8, 2013 Share Posted January 8, 2013 I admit its not the ideal but may work Quote Link to comment
bcd Posted January 9, 2013 Share Posted January 9, 2013 Have you limited the extents of the Section Viewport via the Advanced tab? Quote Link to comment
Dieter @ DWorks Posted January 9, 2013 Author Share Posted January 9, 2013 How about a camera view? It needs to be a section viewport. Quote Link to comment
Dieter @ DWorks Posted January 9, 2013 Author Share Posted January 9, 2013 Have you limited the extents of the Section Viewport via the Advanced tab? If I do this, VW isn't crashing anymore, but it still takes a while. But better than nothing. I have to remember this to get the fastest speed possible! Quote Link to comment
ray isaacs Posted January 10, 2013 Share Posted January 10, 2013 dworks, i always find cutting sections with complex dtms to be messy. limiting extents in all directions including the looking toward direction helps a lot. my sound a bit silly in the bim-age...but once i finally get a clean section thru the dtm, i trace it with polylines, then turn the dtm class off. make further work in section a lot easier and faster. cheers, ray Quote Link to comment

So I can't turn it off. If I only need the section, I just create a dtm section through the menu command for it. But for elevations, I need to see the dtm behind the section line. I really hope this gets fixed in a service pack. Quote Link to comment
