OpenBuildings Raceway 3D Cable Creation Anomaly

3D cable tray/trunking creation is abnormally slow and not created correctly when the cable tray/trunking is less than nominal 2m for OpenBuildings version 10.09.00.83.

I recall no similar issue with prior version.

As interim solution for affected cable tray/trunking less than nominal 2m, I turn off 3D visualization, keep the 2D symbol and draw a solid block to represent the tray/trunking.  

Example below is creation of 750mm cable trunking with 2D symbol placed correctly but 3D is offset extreme far away from the 2D with length 20mm. Any idea what happens?
