Hi @danminneyatsaf,I'll appreciate for your helping very much, Thanks.I have done some arrangement as you say​, but now I am still getting same errors.--Firstly, I have usedGeometryFilter to filter and then set only surface and solid for exit. In result of the workspace, I have got same amount of errors, and even tileset.json has been created wrongly again.As you say, I want to attach the log file. If you want my workflow or assets, I can share you.@talha​I believe you may have shared your .fmw file (workbench) instead of the log file. Would you be able to share the log file with us? You can find this in the same directory as where you workspace is saved. It will be saved in the .log format. Thanks!

Hi @talha​the Cesium 3D Tiles writer only supports Surface and Solid geometries. If your source GML file contains any other geometries such as points, lines or polygons, then this is probably what is causing the error in your log. I recommend using the GeometryFilter to filter for only Surface & Area geometry types and try writing the data from there.
