I am working with 3D pipe centerlines. It includes some arcs that are in the Vertical axis and have a UCS tied to them.
When I run “Convert to Linestring” to removed the UCS to be able to join them to the straight segments the arcs go away.
What happens if you export it as a .dxf from TBC and import the .dxf? Wondering if that will rid the UCS and keep the arc.
That does not work. What I just notice with the UCS and the disappearing lines. Is that if you do an edit and then the convert to linestring it will remove the line completely. You must import the file and don’t touch it only to use the convert command. Its a pain having these convert over with no issue and then you have some that give you issues.
The UCS removal probably does not handle the UCS in the vertical plane - this would be the first time we have come across this specific issue. The UCS has typically been an issue on contours with curves or curbline with curves that we are solving for, and they are UCS near horizontal tilted planes. In this example the UCS is defined in the vertical plane and we probably just have not seen one or been asked about it before now.
If you can share the file I will.have my Devs look at it and get it resolved.

In the past, while using civil 3d, I have simply traced over these. I would isolate the arcs that contained a ucs and just draw my arc over them and then delete the originals. I will say, that I never had more than say 50 to deal with.
Here is the CAD, it has the pipes and their 3D centerlines.

I gave this a try and it doesn’t removed the UCS from those arcs.
Chuck, I think i have a workaround for you. It is a little convoluted but it seemed to work okayish. it removes the vertical curves and replaces them with a VPI’s. export the file as a DGN and reimport that DGN. either only export your vertical curves and reimport them or make sure you run optimize linestring as this will give you corded arcs for all your arcs.

here is an example of when i found this out.
before doing an edit to the line
after line edit
after RPS convert
