I have a CAD drawing (DWG) format that I would like to georeference to my basemaps that are projected in UTM coordinates. This drawing is done to scale without any geographic referencing.

In ArcGIS, the georeferncing toolbar allows for 2 control points in the CAD georeferencing process, so as to preserve the aspect ratio. I would like to introduce skewness because of the projected coordinate system.

Advice required on the spatial alignment of the CAD file to a projected basemap. Cheers!

Once the CAD data is imported, can't you use the Spatial Adjustment Toolbar methods Rubbersheet or Affine Transformation to refine the georeferencing?
