Perhaps you have noticed that when you create a DWF inside of Vault Collaboration your Civil 3D objects show up as various rectangles. This neither accurately reflects reality nor looks visually pleasing.
It’s important to understand that behind the scene the DWF file is being created by DWG Trueview and it has no idea what to do with those Civil 3D objects.
Until now.
If you go here you can not only get the Object enabler for those Civil 3D objects but also AutoCAD Architecture and several others.
Thanks Adam.
