OpenBridge Modeler Question - Variable Constraint on a skewed deck

Question

I have been trying all morning to get my variable constraint on an approach slab thickness to model correctly. As far as I can tell, the parametric constraint only works perpendicular to the bridge alignment. I need to change the thickness of my approach slab at the last 2 feet to a thicker slab but be parallel to the approach slab skew and support lines. Is there a switch I'm missing to tell it to run the variable parallel to my supports??? I have looked everywhere but just cannot find it. I hope this is an easy one. I'm using OBM CE 10.10.00.85

I would recommend taking some time to play around with all the solids & solids modifications tools. Also, go into the Microstation online help found, Solids and Parametric Features are good places to start. My guess as to the best way to accomplish what you want with current limitations is to extract the bottom of slab face, trim it to your 2' section longitudinally, move it down the distance of the additional thickness, then use the Protrusion tool to extrude from that extracted surface up to the bottom of the deck.

To the best of my knowledge you cannot add solids to iModels. You can think of iModels as a PDF in the old 2D workflow. In our old 2D workflow we would draw up the plans in 2D in microstation and when we were done and ready to publish we print to PDF. Same kind of goes for iModels, you wouldn't publish one until you are "done".

Microstation & OBM are both DGN based, so no need to publish to iModel to share/reference into each other. You can even reference in autodesk files into Microstation/OBM DGN file if needed. Typically it is best to reference all models for a project into a single empty container file (DGN), then do what you want with that file (i.e. publish to iModel, send to Synchro for 4D, etc)
