I have a model with surface treatments that I have exported to Trimble Connect directly from Tekla, but the surface treatments won't show in the model on Connect.
I'm sorry that you have faced this problem.
Tekla Structures is not exporting surface treatments when model is published to Trimble Connect using Trimble Connector. You can use IFC export and you should get the surface objects also to Trimble Connect, should work in Trimble Connect Desktop and Trimble Connect Web.
Only problem there is that the surface treatment does not have the texture exported.
I will create ticket for this for the IFC export. And one ticket for Trimble Connect Mobile for showing the surface objects also.
