How to match deck crown to top of cap (abutment or bent) slope?

Hi Daniel,

If you want to make the cap of the pier to have a form of inverted V as the deck, this is not possible with normal pier templates. The cap is always straight but if your deck has a rotation angle or different slopes, the cap will adapt to the elevations of the bottom left/right deck elevations thus resulting in an inclined cap.

You can achieve what you are seeking with Functional Components as presented here.

Hi Vlad, 

Thank you for the reply, the video was useful. I have another question regarding modeling a deck with a break back. The following image depicts how it will look on plan view:

What is the best way to model this deck? 

Hi Daniel,

You can model break back using the modify solid option from the MS tools inside OBM.

Please read this document prior to do the modifications.

Properties of User Modified Solids - LARS | LEAP | OpenBridge | RM Wiki - LARS | LEAP | OpenBridge | RM - Bentley Communities

These modifications should be done in the last stage of design i.e. after everything was modeled correctly, you will modify the deck solid. If you do a solid modification and then you add/modify something in the model that will trigger an update of the bridge geometry, your solid will reset to the initial form created by OBM thus losing the solid modification.

Thank you for your response Vlad. Will this same procedure apply for an abutment with a break back? like the one depicted below (plan view):

You can use Functional Components for complex models or modify the solids created by the OBM normal templates.

Got it, thanks! It will be cool for future releases of OBM to have the ability to model break backs with an easier method to expedite the process. Break backs often come up on bridges that I've worked on.
