Reference Origin & Master Origin

How to get the masterOrigin and referenceOrigin form Reference file attached

What programming language are you using?

C programing Language using MDL api

StatusInt       mdlModelRef_getGlobalOrigin  
( 
DgnModelRefP       modelRef , 
DPoint3d*       pGlobalOrigin  
); 

The master itself describes the all models in a DGN, so you have something this is called "active model". From this you could use the modelrefP. Also you get from each reference a modelRefP this could be used also.

There's a number of mdlRefFile_xxx functions.  You will find them documented in the MDL Function Reference help file.

#include <refernce.h>
#include <msreffil.fdf>

ReferenceFile* refInfo = mdlRefFile_getInfo (attachment);
// ReferenceFile includes several nested structs
Ref_display* display = &refInfo->display;
// Ref_display contains the master origin and reference origin in UORs
DPoint3d masterOrigin = display->mast_org; 
DPoint3d refOrigin = display->ref_org;

Thanks Jon for your reply,But the coordinates i got from this mdl api is far away from the original coordinates of my reference file.

You may need to adjust those points by subtracting the global origin.

Also, keep in mind that most MDL functions work with units-of-resolution (UORs), not master units.

It would help to tell us more information to help with our diagnosis.  'Far away' is a little vague...

1. Master origin coordinates returned by your MDL code
2. Reference Attachment Properties
3. Reference origin coordinates returned by your MDL code
4. UORs of your active DGN model
5. Global origin of your active DGN model
