Can't create more than two control points when georeferencing a DWG.

[Gustavo_Souza]

I want to georeference a DWG file to make it a feature class.

However, whenever I start adding controls points, the option becomes unavailable after I add 2 controls points. But, 3 is the minimum necessary to have acceptable accuracy. 

My reference is just the regular esri basemaps.

This is what happens as soon I add a control point.

Hello Gustavo: 

I never done that in ArcGIS Pro with vector data. But I will suggest the following: (1)  first  convert DWG into a FC.Conversion CAD To Geodatabase

Afterwards, (2) define and then use (3) Project tool,  to project the dataset in desired projection.

Define Projection Tool 

Project Tool

Maybe it doesn't allow you add points because it already has some geographic information?

Or, if you are working in the software DWG file was created, assigned the projection from there. It should work when you inserted the file into GIS.

Cheers.
