This may be more of a Microstation question but I'm using the process with Openroads. I am using the "Solid by Extrusion Along" to create 3d existing underground utilities. I'll first use the Horizontal "Complex by Elements", then create an offset vertical from the existing terrain. That results in a 3D Linear element. After applying a solid to the linear element, I get a nice pipe circle on the cross sections.
The problem is...sometimes the "Solid by Extrusion Along" works and sometimes "Unable to generate geometry". I can't seem to get a feel for what the criteria is for it to work. Sometimes a complex horizontal (lot of PI's) and complex vertical will extrude. Is there a max number of horz.. or vert. PI's? Don't use curves? Or is there bettter way to accomplish this task?
One way I have accomplished this is by using a MicroStation smartline to create the utility line. I then assign a Feature Definition to the utility line. This Feature Definition has an Element Template tied to it. The Element Template has symbology and and Active Point cell. The Active Point cell calls a cell from a cell library. I then create a profile of the utility line and either assign elevations from a utility survey or a general offset.
Anytime the corridor slices thru and hits the utility line the cross section shows the cell. This works well as we can place text in the cell that represents what the utility is and what size.
