Hello all,

I'm using 9.3.1 ArcInfo.

Ok, I read how to georeference CAD data. I have been doing it that way for a while. But there has to be a better way...Anyone?

I read why I can't have more than 2 control points. And I understand that. But I'm having to open the dwg in CAD and plotting a pdf, then creating a tiff from the pdf. Then georeferencing the tiff in ArcMap to the aerial and then trying to get the CAD dwg at least close to that. Then recreating all of the data from the tiff into a geodatabase by manual editing. Then creating annotation from the CAD. Then going back and moving the annotation to where it should be.

So, why can't I have the option of a different kind of transformation with CAD data? Is it hard to program the software or something?

What do other people do when they have this problem? I finally got to a point where I would like a better way, but I don't think there is one. ugh.

Thanks for your ideas,
