Hello I have been working with my client for years building SU models and exporting them in KMZ format to Google Earth. Now that Earth is going away they are migrating to Cesium. Cesium from what I understand only supports COLLADA files and it seems that the .dae format file sizes are much larger than .kmz. As a result my client is wanting smaller file sizes with less detail. Is there anyone out there that is having the same issue and how to solve.

Hello I have a .igs file that I need to import into sketchup.
I am using SketchUp 7, on a mac.
