Civil 3D Reference Point

[KeyBored]

In Land Development Desktop you could setup a reference point instead of using 0,0   the reference point could be 10000, 10000 and all of the entities in the drawing would reflect the revised reference in the coordinates for each entity. 

Problem: I have a set of construction plans that were done before the plat was finished. The plat has since been moved and rotated. I need to move and rotate all of the proposed construction to the revised plat location. The problem is that if I move the base drawing with the proposed construction and rotate it the construction plans will have to be revised completely. 

If I can change the reference point and rotation angle I could insert the revised plat and rotate it to the proposed construction but the coordinates would reflect the proper coordinates based on the revised plat.

Is this still possible?

No BPNR in civil3d.

Maybe a survey guru has a way?

Yeah, the problem here is that Civil 3D is based on following a world coordinate system. We used to use the user coordinate system from vanilla AutoCAD way back in the day. Civil 3D and it's modules don't like UCS at all and we had to abandon it's use. Civil 3D will want to force you to move your design to the proper coordinates and re-adjust all of your drawings. I just had two projects that both required a similar shift from the finished design. Because they had to remain in our state plane coordinate system to be compatible with other design efforts in other deptartments, moving them in plan and adjusting the plan sheet sets was the only viable option.

Since I work alone I would probably do the following.  I suppose your reference to "the Plat", you are referring to a Record Plat of the development.

I would use a version of the Record Plat as the drawing that I am working in and xref the construction plans into this.  Move and rotate the xref to align with the Record Plat.  Now your coordinates should match.

I will now go directly to my man cave and hunker down.
