North Rotation - Basis of Bearings

[cujo]

I'm curious how others are handling this situation.
Very happy with Carlson, have 8 seats and 3 of SurvCE.
Before I was using LDT.

We often are putting several maps together in a basemap. As often as not, the 2 or 3 maps might have different basis of bearings. The common lines from one map to another are of course the same line, but have different "record" bearings on each map.

A common solution (what we're doing right now) is to key in the maps separetly on assumed coordinates, then translate and rotate one to meet the other.

With the high number of CORS stations, now 95% of our surveys come into the office on a grid basis of bearings. We no longer set ourselves to a bearing from long ago, everything is GIS ready. Right off the bat, I have a map with a bearing between 2 found points that I want to set the map to. As described above, I have to key in the map and then rotate it to match the found monuments.

Now ... what I used to be able to do: In LDT I was able to set a "North Rotation" Of the various options I could pick two points or a line in the drawing and assign that an azimuth, or more likely, a quadrant bearing.

So, my control survey says this line is N05-00-00E. I have a map from the 60's that calls this line due north from whatever basis they decided to use. I want to put this map into the drawing and there are numerous sidelines or parcels that I want put in base don the relative angle between the lines, but relative to the found points.

If I told LDT that the line or points in the drawing needed to be referred to as North, then any other command from the COGO menu that promted or reported a bearing or azimuth would be rotated 5d clockwise to match the "north rotation". This rotation was only a local software setting, the CAD drawing didn't know what I was doing and it would be invisible to anyone else I sent the drawing to. We would use the feature many times during the course of bringing different maps into an agreement of basis and then turn the whole thing off at the end so we were reporting and labeling in our correct basis (not the maps).

Is there anything remotely like this in Carlson? Can I temporarily assign a rotation to the bearings?

I remember before LDT another method I used was to determine the difference in basis between maps and then on all but the main one I'd go in with a pencil and "correct" all the bearings to what I was going to key into the COGO routines.

Feel free to suggest other workarounds or point out where I'm missing this in Carlson Survey.
