REVIT TO CESIUM - Cylinder conversion error

Hello, I have a REVIT file which contains some cylindrical objects (e.g. pipes) and when I convert the model to cesium, it creates hexagonal shaped pipes instead of cylindrical ones. Is this intentional or can I bypass this behaviour somehow?

 

NOTE: The Revit model is offset according to it's Reference Point. Also, the Data Inspector shows the cylinders correctly where it is an aggregate geometry with with many many IFMEFaces.

HI @mrdado12345​,

If the cylinder looks correct in Data Inspector, then the culprit is likely coordinate rounding on the out to Cesium. The Cesium writer will reproject the output data to the geocentric coordinate system required by Cesium, so for good results, the source data should have a coordinate system set on it.

 

Does the Revit data show a coordinate system set when you view it in Data Inspector? You may need to change the Revit reader's Revit Coordinate System to Read to 'Georeferenced'.
