I am not sure if this is one of the wacky challenges with C3D or a glitch in my drawing.

I have an alignment I was editing to get a specific geometric configuration. After much trail and error in which the last two PIs were removed I ended up with a shortened aligment missing the last two segments, a tangential arc and short line segment. I appear to be able to add the arc and the line segment to the alignment but it does not appear to update the alignment data.

Now I have an alignment which when selected, highlights the entire alignment including the last two elements which do not appear to be in the alignment definition. I can select them and they are identified as the alignment but they do not label or station. Is there some way to have the alignment reread and update it's definition?

Is this a known issue? Unique?

I can just redefine the alignment which seems to be the requirement but I am curious as to what is going on.

Any ideas?
