I have serveral record maps, they are all on different basis of bearing.
In LDT, this was simple, just change the north rotation, and draw the line with the bearing on the map, then reset the north angle.
In Civil 3d, the only way I can think of, is to draw the parcels using the hard copy map bearing, then rotate the line work to the common basis of bearing.
My problem is that after I rotate the line wrok, there is no way to compair the bearing to the orginal or another map.
My questions is:
Is there a way to compare line work bearing to a hard copy map on a different basis of bearing without rotating all my lines, simular to LDT.
Is there a better way to draw lines based on different Basis of bearing.
Transformation and UCS has not effect on drawing or listing line bearing and distance.
Thanks
Scan your hardcopy to PDF and do a PDF underlay, rotating as necessary.

You work with what you have... and if all you have is a badly scanned map, you make do.
Scan a drawing is not an option. Using Xref, is an option, but still not great.
Our draiwing are very preicise. By enter the data, I can verify that the map is correct (somer are not). There are many maps that are not to scale, so scanning would not work.
When we are finish, we use the drawings for setting monuments, constuction staking and takeoff. So when we change the bearing and distane of a line, the line must change, not just the text.
The problem using xref is managing the extra files. However this option may work for me as backup data.
I need to look that this more, thanks for this option.
The separate file with an insert or Xref works fine. However we often deal with over 100 deeds at once. We create an area in the drawing where we plot the parcels using the deed bearings, copy the parcel lines and make the copy into a Group. Then we move and rotate the Group as necessary. If we need to adjust the parcel because of misclosuer. We adjust the copy before turning it into a group.
So we still have the original plotting that has been checked for closure and an adjusted copy that is in the drawing coordinate system.

I've attached a screenshot of what it looks like. It doesn't contribute to the drawing size very much since simple lines and curves are miniscule when compared to Civil 3D objects.

It all depends what you have on the hardcopy plan. You can recreate it if you have enough data to do so. Many times, hardcopy plans that I have do not. If I want to get an idea that they are representative, a quick scan and overlay will provide an answer as to whether or not they make sense.
And then one sends a crew to the field to ascertain the truth as a plan is simply a representation of the survey. Without field notes to back it up, it's just a picture.

Eric, what you're suggesting has nothing at all to do with the accurate, detailed analysis that the OP is asking about. What you're referring too sounds like an architect or planner tryijng to check someone elses plans or something similar. We're talking about detailed survey datat that requires accuracies to 0.01 and angles to the second. A pdf will do neither.
