Returns the offset of origin of the virtual coordinate system.
GSErrCode ACAPI_Database ( APIDb_GetOffsetID, API_Coord* offset );
Parameters
- offset
- the offset of the origin of the virtual coordinate system
Return Values
NoError
- The function has completed with success.
APIERR_BADPARS
offset
isnullptr
APIERR_BADDATABASE
- the command was called for a non-2D window
For other common API errors see the API Errors document.
Remarks
This function is used to get the offset of the origin of the virtual coordinate system from the origin of the world coordinate system.
This origin was introduced in Archicad 9 to reduce the inaccuracies, which could happen if the model was far away from the origin of the world coordinate system. This offset is set after a file is opened, if the so called ‘weight point’ of the model is far enough from the origin of the world coordinate system.
After that all coordinates coming from the API are measured from this origin.
Requirements
- Version: API 6.1 or later
- Header: APIdefs_Database.h
