Assign a value to system variable CGEOCS

aplitop — Wed, 23 Oct 2024 07:27:54 GMT

I would need an ObjectArx method or a way to execute the GEOGRAPHICLOCATION command in a completely transparent way for the user, passing it some parameters like reference point or file, and the EPSG code, so that it assigns a value to the CGEOCS variable.

Maybe AcDbGeoData?

I've never used it though

Thank you for your reply.
Related to the AcDbGeoData class, I found this article (https://adndevblog.typepad.com/autocad/2016/04/positioning-geographicmarker-using-objectarxx.html) that sets up a new SRC, and I want to try the example, but this line :

AcDbObjectPointer<AcDbGeoData> pGeoData;

gives me a error :

error C2039: ‘_close’: is not a member of ‘AcDbGeoData’),

I added the following includes:

#include ‘AcDbGeoCoordinateSystem.h’
#include ‘dbobjptr.h’
#include ‘dbGeoData.h’
But it still gives the error .

Any idea what to do so that I don't get that error and I can test the example.
Thanks for your help.

Regards.

#include ‘dbGeoData.h’

AcDbObjectPointer<AcDbGeoData> pGeoData;

compiles fine for me.
