I’ve attached back JohnsCalibration.zip. It has a trv file you can open with the traverses I used.
Your Objective
————–
If I understand what you are asking, you don’t want to use a calibration created by calibrating from Field-Measured to Deed-Points. Instead, you want to use a calibration that mimics a manual translate / rotate of the Field-Measured to Deed-Points.
What’s the Difference?
———————-
With a manual translate/rotate, you control the transformation from Field-Measured to Deed-Points. If you had calibrated from Field-Measured to Deed-Points, the calibration would have determined the transformation. One of the characteristics of your manual translate/rotate is that there is no scaling. Either way it fine by Traverse PC. You are always in charge of making decisions like that.
What not to do then
——————-
That being the case, you do not want to create a calibration From: Field-Measured To: Deed-Points.
What you do want to do
———————
Instead, you want to do this
1. Create a duplicate of Field-Measured (TPC names it DUP-Field-Measured) with its own points, and translate/rotate that traverse to Deed-Points.
2. Create a calibration From: Field-Measured To: DUP-Field-Measured.
Now, the calibration that is created, mimics your translate/rotate.
Let us know if this is what you are after.
You can also play around with creating a calibration From: Field-Measured To: Deed-Points and turning of scaling. Might also get you what you want.
