a)How I can copy some drawing objects from source dwg to target dwg in the same dwg session by using c#.Also I have to take care of Coordinate system of target dwg.Is it possible that copied dwg objects automatically conveted to the target coordinate system?

 

b)  How I can extract the coordinates system information of a AutoCAD map drawing and set the coordinate system of other dwg according to extracted information by using c# .Net.

 

 

Thanks

Hi,

 

>> to the target coordinate system

If that "coordinate system" is just a UCS then:

  • there are a lot of possibilities to copy objects from one drawing to another, I preferre (in most cases) the WBlockCloneObjects (>>>details<<<).
  • If you have to verify that this copy-process has to follow some UCS settings you will have to use the TransFormBy (>>>details<<<) functionality as the WBlockCloneObjects copies using WCS-coords.

 

>> the coordinates system information of a AutoCAD map

Ok, in case of reprojection between different geographical coordinate-systems you can't do that with TransFormBy, you have to use the ADEQUERY functionality. For that you find samples in the Map3D-ObjectARX-kit.
