OBM Create Substructure Drawings Cut Plane Orientation
Adam Swierczek
I'm using the built-in workflow for creating substructure drawings as seen here. When I click on the pier the automatic section plane is shown at an angle, not parallel to the Support Line. The angle appears to be random, not associated with global coordinates…

Custom Load Group and load combination (wind load)
Dilip Matange [Bentley]
When we use new/custom load groups the program is not generating Load Combinations for the respective Wind loads as it does when using default load groups. It seems to be generating as if we were using the cross combination option. Current LEAP Bridge…

How to reduce Load Combination processing time?
Dilip Matange [Bentley]
The Load Combination and Analysis is a very memory intensive process. If you have too many loads you should try reduce them so that # of generated loads is less and in turn the analysis will run better. Here are some steps that may help. One of the…
