I am in need of some guidance. I am trying to make a 2-tiered eccentric manhole. This is very similar to an OOTB part called "Eccentric Cylindrical 2-Tier Circular Frame SI". I decided to simply modify that part to my own specs. These are the changes I made to it:
After all these changes were made I ended up breaking the thing. I have found that the barrel height does not stay put. If I change the barrel height in structure properties it will not change and if a connected pipe changes then the barrel height reverts to something different. I have also found that changes to connected pipe do not reflect in the structure. If I drop a pipe invert the bottom of the structure does not follow. I've attached my DWG and XML for anyone who can help me out. Any ideas?
BTW: Files are AutoCAD Civil 3D 2011 (metric)
