Geographic registration on AutoCAD file.

Question asked by starrycheng on Jul 27, 2017

Why  I  only can do  registration use  two points on AutoCAD file  every time ?   

Seven points to determine the location of the map, isn't it?

I chose 14 points to positioning,use  two points every time.

From the first group to the seventh group.Each time  will generate a "WLD" file.

What is "WLD" file about?

Is it only the last two points is work?    The registration of the previous 6 group points  is not action?

How  to  make  geographic  registration  is accurate on AutoCAD file use more than two points?
