Even if you found a viewer that works, I think you would not be pleased with the results. It took me a while to find something that works until i found the VRML Viewer 3 (mentioned above). I don't think it's available anymore but if you are interested I can e-mail you the installer. I am attaching a screen capture of a 3D model created in 3D Analyst and exported to VRML and loaded into the viewer. The other screen capture is of the model itself in ArcScene. Unless you are doing something VERY simple, then the 3D exporter is completaly useless.  If you intend to share models, you are probably better off designing 3D models in SketchUp. Even the Collada export does a really bad job; you need to explode the models and re-paint the faces to even make sense of what it is you are looking at BUT. It is georefenced and it does provide grounds for sharing models between SketchUp and 3D Analyst. ... View more

Collada export is new in version 10 so this blog article only applies to version 10. This only means that you cannot export ArcGIS multipatch to SketchUp but you can use the SketchUp 6 plugin to export TIN and vector feature classes. (In version 10 vector featurs cannot be easily exported unless polygons which need to be converted to multipatch first) In ArcGIS 9.3.1 and older you can use a command to import SketchUp 6 models but georeference information is not imported. ...

This one worked for me. Although, to be honest, I doubt any of the viewers are going to 'really' useful. I though i could do the same but... Well, you will see what i mean; http://www.vias.org/pngguide/chapter06_08.html It would be MUCH more usefull if 3D Analyst could export to say SketchUp.  I've gone through a lot of trouble to convert a 3D model build in ArcGIS to SketchUp so that the end user can have an interactive, scaled product. There are some browser plugins that I've tested and they do display the model but it's only good for zooming, rotating and such... ... View more

Thanks Nathan. It worked. It takes a bunch of steps but the final result is the same as with the old Sketchup 6 extension. Yes, I exploded the group, applied a uniform color to all surfaces and it was good. My next question is about exporting vector (point, polygon, polyline) data from ArcGIS to SketchUp. Naturaly, I thought export to KMZ then import to sketchup would work but the files exported from ArcGIS fail to import to Sketchup. (But do open fine in Google Earth) - Any Ideas?  I also tried DXF and DWG export from ArcGIS but the scale is wrong and i would have to scale manually in SketchUp. Sketchup 5 used to import shapefiles natively but that is no longer available. The are some ruby scripts but they don't work... ... View more

I forgot that similar topic was discussed last year here: http://forums.arcgis.com/threads/626-Beta-10-ArcScene-SketchUp-Plugin-No-longer-Functions Assume that this thread deals specifically with how to export TIN to Sketchup and bring it back to ArcGIS. As for the first part, i tried the following suggestion by Nathan Shephard, ESRI: (1) Can TIN be exported to COLLADA in ArcGIS 10?     - Not directly, we only have direct export of multipatch features to COLLADA     - You can, however, simply use the 'Interpolate Polygon to Multipatch' GP tool to convert the TIN to a multipatch feature for a given polygon / extent (as a pre-processing step), and then convert that multipatch to DAE. 1. use the Tin Domain tool to create a the 'Interpolate Polygon to Multipatch' tool required Input Feature Class 2. Run the 'Interpolate Polygon to Multipatch' tool (used default strip size: 1024) I symbolized the multipatch to only show line and overlaid it over the TIN 'wire mesh' and it seemed some lines were missing from the multipatch as it it were somehow simplified. (Later i compared the SketchUp sandbox and all faces seem to have transferred over correctly).dea error appears telling me that the import cannot be validated. 3. Run the Multipatch to Collada tool 4. Import Collada to Sketchup (An error appears informing us that the import cannot be validated - ignore and continue) 5. Initially, the imported 'TIN' looks NASTY; faces appear reversed with alternating dark and light colors, definitely nothing like the smooth export from the now legacy SketchUp extension. 6. Select the Sandbox group and explode. 7. Select all faces and paint with common color. 8. Group and adjust smoothing. I used the new 'Add Imagery' in SketchUp and the TIN surface seems to be correctly geo-referenced This was only a simple model but it seems to yield the same results as with the 'Export TIN Google SketchUp 6' extension. The one issue i am having now is with exporting vector features to KML and succesfully importing them into SketchUp 8.  SketchUp 8 import of such features crashes. ... View more

(1) Can TIN be exported to COLLADA in ArcGIS 10? - You can, however, simply use the 'Interpolate Polygon to Multipatch' GP tool to convert the TIN to a multipatch feature for a given polygon / extent (as a pre-processing step), and then convert that multipatch to DAE. I tried it and the initial result appears very strange.  The whole surface has to be exploded, all faces selected and painted with a uniform color, then grouped and softened as required.  Strange but works. Kind of. I guess the question is how to make sure that the triangle faces in TIN translate accurately to the multipatch. I suppose this is controled by the 'Strip Size'. The tool help states: The Maximum Triangle Strip Size value must be 3 or larger.  The recommended range is between 128 and 2048. The default setting is 1024 but at this setting the resulting multipatch is much 'simpler' than the original TIN.  Is 2048 the maximum strip size. What is the recommended setting if i would like an identical 'wire mesh' as I have in the TIN. ... View more

Likely not possible with an out-of-the box tool.  TIN is more flexible (rather than Terrain Dataset) when it comes to editing, manupulating the surface and geoprocessing so i would recommended to use TIN. You could then clip out the road area from the original TIN then use the TIN Editing Toolbar to 'flatten' the road area manually. Unfortunately this would have to be done on node-to-node basis. You could also create points or point groups along the buffered centreline then manually assign elevation values to the points then create a new TIN or incorporate the new nodes/breaklines into the existing surface. Alternatively you can design the road in a 3rd party application such as Google SketchUp 8 or AutoCAD Civil 3D the import the model into ArcGIS. Google SketchUp models can be imported as multipatch. See this blog post: http://sketchupdate.blogspot.com/2010/10/arcgis-10-and-sketchup-8.html#links Civil 3D is the tools for designing roads although exporting the models is not as seamless but, it is possible. Attached is an example of a haul road designed in Civil 3D exported as XML, converted to XYZ and reconstructed in ArcGIS as a TIN Surface then overlaid over the source LiDAR data. ... View more
