Hello, I am doing a project related to integration of BIM and GIS and I successfully import the BIM (revit project) to shapefile in ArcScene. But now, I do not know how to import the shapefile to Revit. The following method I was tried but failed: 1. convert shapefiles to DWG format by "quick export" in "data interoperability" in ArcScene. the result loading for more than 12 hours so I cancelled it. 2. convert shapefiles to CityGML by "quick export" in "data interoperability" in ArcScene. then convert the CityGML to DWG format via FME data conveter the DWG file was linked to Revit but the file cannot be loaded into Revit. 3. export shapefiles to CAD in ArcScene. failed to execute in ArcScene. The result stated that the operation was attempting on an empty geometry. 4. convert shapefiles to IFC standard in FME data converter The outputted IFC is only 2KB. No feature was imported and shown in Revit. The shapefiles are many component of a building. Any suggestions to import the shapefiles to Revit? Thank you very much. Ying ... View more

Hi, I want to create shadow of a building at different time in ArcScene but I am a beginner of using ArcScene so I am not familiar with this. I am using ArcGIS 10.2.2 version. I tried to use "sun shadow volume tool" in "visibility" in "3D analyst tool" but I do not know how to present the shadow in different time and in animation. After that, I found some reference on the internet, it is using "Skyline" and "Skyline barrier" tool of "3D analyst tool" to create shadow of the building. However, I am not understand how to define the position of the Sun and also how to create an animation to present the shadow in different time. Or can I do this in ArcScene? Thanks a lot. ...

Hello everyone,   I imported the CityGML (.gml file) in ArcScene but there is "no geometry" and nothing imported. The ArcGIS I used is ArcGIS 10.2.2 (Advanced Single User- 60 days trial version). Can this version read CityGML file?   I found some reference said that it needs professional licensing level to read and write CityGML. How to get the professional licensing?? Any suggestion and comment? Thanks a lot!!!!!!!!!!!!!!! Ying ... View more

Hello everyone, I am doing a project to analyze the shading effect of a building. I want to use the Sun shadow volume of 3D analyst but there are some errors and no result given out. I try to import different data but there are errors that the sun shadow volume is not created. As the building model that I had is a IFC model, I first import the layers of IFC model to create the shadow. Second, I try to save the data of the IFC as a multipatch but it cannot works. Then, I try to create a extruded building model then import it to do the shadow analysis. There is no result. The result message are that the output feature class is empty and the error is 999999 that error executing function. It is failed to execute the Sun shadow volume. Please help me to solve the problems as I am a beginner of using 3D analyst, thanks a lot. Ying ... View more
