Peter Eichel Posted May 4, 2009 Share Posted May 4, 2009 Why are my DTM renderings patchy? I apply a natural grass turf texture and there are large open areas of gray. Also, is there a big improvement regarding DTM from VW12 to VW2009 and where can I find detailed literature or videos on VW's DTM?

rkraybill Posted May 4, 2009 Share Posted May 4, 2009 What happens if you change the 3D Style setting in the IOP (assuming that was available in VW12 - don't have it installed)? Quote Link to comment
Peter Eichel Posted May 4, 2009 Author Share Posted May 4, 2009 Hello Mattc, firstly, it's called the OIP (object information palette)not IOP and yes I've done that and more. I'm going to update to VW's 2010 in the fall assuming they have these *^$%*BUGS worked out. I'm committed to VW's because I've spent years learning their software and have no intention of learning another. In all fairness though, their software is all I could ask for except for the BUGS!

Bob Holtzmann Posted May 4, 2009 Share Posted May 4, 2009 Speaking of bugs, VW 12.5 is a free update, and it's much more stable than VW12.0 ever was. The 12.5.3 updater is in the downloads section. Quote Link to comment
Benson Shaw Posted May 5, 2009 Share Posted May 5, 2009 May not be relevant, but objects, including DTM, sometimes deteriorate if far (miles) from drawing origin. I had a DTM do that patchy thing. When relocated to origin, the patchiness went away. The distance from origin was many 1000s of yards due to ACAD ref points in survey data. This may be fixed in 09 - Haven't investigated. -B Quote Link to comment
CipesDesign Posted May 5, 2009 Share Posted May 5, 2009 Peter, If you can post your file I'm pretty sure one of us can figure out how to get rid of the "patchy" areas, or at least try to diagnose what is causing them. I have a hard time remembering back that many versions, so having the actual file would be quite helpful. Quote Link to comment
Bob Holtzmann Posted May 5, 2009 Share Posted May 5, 2009 The second part of your questions, about the DTM tutor videos, has the answer here: http://www.nemetschek.net/library/index.php?movie=12movies Scroll down to find the DTM video for version 12. Quote Link to comment
Chad McNeely Posted May 5, 2009 Share Posted May 5, 2009 Why are my DTM renderings patchy? I apply a natural grass turf texture and there are large open areas of gray.... Sounds like you used 3d polys with a solid fill to create the DTM? If so, remove the solid fill of the 3d polys, or uncheck the button to keep the source info when you create the DTM...

CipesDesign Posted May 5, 2009 Share Posted May 5, 2009 Chad is exactly correct. This had slipped my mind ;-) Quote Link to comment
Peter Eichel Posted May 5, 2009 Author Share Posted May 5, 2009 Gentlemen: Thank all of you very much, it was the solid fill. Right in front of me the whole time! Quote Link to comment
CipesDesign Posted May 5, 2009 Share Posted May 5, 2009 Peter, et al: If (like me) you use polylines to create your DTM, there is a bug as follows: Select UNFILLED polylines and CONVERT TO POLYGONS. Make sure all polygons are UNfilled. Select Polygons and use the 2dPolys to 3dContours command and notice that all of the newly created 3d Polys (contours) are FILLED. I had forgotten this behavior (from version 12.x.x) and therefore I'd guess that it has been fixed in some later version. Anyhow, glad you found joy! Quote Link to comment
