![]() I am not really sure what the workflow should now be if the recommended ESRI workflow doesn't really work. I was able to create large Sketchup models in the past (up to version 9.3.1) with complex TIN, polygons, points and lines exported directly from ArcGIS using the SketchUp 6 plugin. I then decided to do it the other way around (build the model in ArcScene and add SketchUp models to it) but I don't seem to be able to replace simple multipatches with models edited in Sketchup. This either fails if the surface is not very simple or yields unusable results. Exporting complex surfaces to COLLADA almost always fails and since TIN cannot be exported to SketchUp directly, it has to first be converted to Multipatch. png file type, then navigate to the PNG imagery exported in Step 9. This will keep a single file on disk for that feature, representing the most up-to-date state of the 3D object. Activate just the top face of the overpass with the Select tool. When iteratively updating a multipatch feature by exporting it to COLLADA and making changes outside of ArcGIS, export the feature to the same location each time. Multipatch to collada - it creates a collada file as well as a kml with the spatial reference of the model. The algorith decompose the polygon area into a set of triangles. I would provide more information, but SketchUp does not provide anything other than ‘Failed’. The importing of Collada files would appear to be broken. Use the Select tool to select the model, then right-click and select the Explode option. Triangulation method to create multipatch objects (decomposition of polygon surfaces) Which triangulation method or algorithm does arcscene use to create multipatch parts (patches) as you see in the attaching picture. Using SketchUp Light I am having an issue importing Collada. I initially wanted to build the model in SketchUp but it seems impossible to export anything out of ArcGIS without the SketchUp 6 Plugin for ArcGIS. Open SketchUp and use File > Import to import the COLLADA model (.dae) saved in Step 7. If the multipatch feature class you are converting is in a projected coordinate system, the tool will create a KML file in the output folder which will assign geographic coordinates to the 3D models in the COLLADA files'. Why can't I replace the SketchUp model itself? Is this procedure only meant for very simple models? COLLADA is a 3D model format that is supported in many 3D applications, including Google Earth. Some faces can be seen from the reverse side. ![]() This only seems to (sort of) work if I export from SketchUp to Collada but only fully closed faces (and only some faces) are visible in ArcScene. ![]() The Model field holds a Binary Large Object that can be downloaded to a 3d authoring tool for editing. Note that this process will not use a datum transformation, which may result in positional discrepancies when viewing the KML.
