+8I have several DWGs, all of which have not been spatially coordinated, however each has 3 set points with an annotation referring to the National Grid X&Y.
I am essentially trying to understand if I can take these 3 points and assign the National Grid coordinates provided as the annotation?
+23Use AffineWarper with Control input as 3 lines with first vertex in your original location and second vertex at the specified location from annotation.
+8Thanks! - Most appreciated for your reply.
I have taken this and attempted it myself. My understanding is that I need to create 3 lines representing the offset of the 3 XYx from where they are currently being drawn to the exact location. I then input this linear feature in as the "Control".
However there doesn't seem to be an corrected output?
It may be the fact that the DWGs I am dealing with are actually linear (I am looking at moving building flood plans) - example below.

Can you provide some sample data?
Maybe you have some weird feature types that don't get processed.
+8DWG attached. I've had to remove most of the data, but should give you an idea.
Thanks again.

Apologies. I keep forgetting to "Reply" rather than to create another comment. DWG attached below

I looked at your sample data. The destination coordinates are wrong. I can't get something normal even manually. I don't think you are trying a Mobius inversion 😃
AffineWarper assumes a 3D operation and needs 4 sets of points. You can try RubberSheeter or figure out the math and do Offseter, Rotator and Scaler.
But first, get some correct data.

Thanks. I modified the original DWG to ensure it sits in the correct location @ OS, so just a simple extraction workbench.
Thanks again :)
