Point shift on convert Land desktop points

[AllenJessup]

I had inserted a Land Desktop drawing containing points in to a C3D 2012 drawing. There was a small difference in coordinates. I used Autocad move and rotate to adjust. This was fine because I only needed a visual reference. Now someone wants the information and I need to convert the Aecc points to Civil cogo points.

The problem is that the convertldtpoints command doesn't use the location of the point marker as the coordinates for the converted points. It uses the Northing-Easting stored in the AECC_Point object. Those are the pre-adjustment coordinates.

Does anyone know a way of getting around this?

I remember hitting this on one of my very first C3D projects.  My solution: note to self "Convert First, then Move"

Not sure if this is going to help you now though.

That's near to what I ended up doing. I marked 2 solid points. Then I did the conversion and let the points revert to their original coordinates. Then I did a move and rotate based on the positions I had marked.

The only other challenge was selecting only those points I'd just converted and not points already existing in the drawing. I locked the layers that contained the points I didn't want to move and then used QSelect to select all the Cogo points.
