AutoCAD Civil 3D

[#1]

I have used the intersection tool to create the alignments and regions to be incorporated into an existing corridor.  The tool creates some additional regions which I do not want so I delete the regions I do not want.  I rebuild the corridor and everything looks good.  I save the drawing, close, then reopen the drawing and those dastardly regions have reappeared!!

Any ideas, help appreciated.

Hello Jon,

Can you attach some simplified / example file where this problem occurs?

The issue seems to have resolved itself?  I'm not really sure why this was happening maybe just one of those things.  I can't even reproduce it.

Well it seems that this issue has not gone away, the magical reappearing regions are back and they are wreaking havoc with the corridor.

I have attached a screen shot showing an example of the corridors that autorecreate, they seem to be a function of the intersection creation tool.
