Change original coordinate systems Autocad Map

 Hello, my question is very simple. Installation of Autocad Map 2012 provides a list of thousands of coordinate systems, datums, geodetic transformations, etc.. but I see that the system doesn't allows editing (they are read-only) and always I have to create new systems, new datums ... Is there any way to make it editable? Thank you very much!

Hi,

 

I would not suggest to modify existing coord-systems, but to define new one you can use command _ADEDEFCRDSYS

The problem is that Autocad Map 2012 by default, performs a given geodesic transformation (between 2 datums) that is not valid (It is correct, but I need more precision). In my country (Spain), we used transformation grids (gsb) to make that change between two datums. If I could edit the default geodetic transformation would not have to create new datums, coordinate new systems, new geodetic transformation ... but as it is read-only ... thanks!

Perhaps with the new option "path geodesic transformation" can do something, I do not know ...
