How to find the offset of a reference file.

How to find the offset of a reference file

There are two relevant properties of the Attachment object...

• MasterOrigin
• AttachmentOrigin

Thanks Jon...brain was on food deprivation or something.  I throwing the wrong calculation on the AttachmentOrigin earlier by mistake, so moved on rather than try and figure out what I was doing wrong.  Checking now, I have verified the AttachmentOrigin is the actual origin in UOR before any offsets or rotation is applied.

Thanks again...

I am still confused about MasterOrigin and RefOrigin. In some cases, we can't get correct reference offset by using MasterOrigin - RefOrigin.

Below is a workable approach to get this offset. Simple!

DPoint3d offset;
Transform trans;
double uor = mdlModelRef_getUorPerMaster(ACTIVEMODEL);
pAttach->GetTransformToParent(trans, false);
trans.GetTranslation(offset);
WPrintfString wStr(L"offset = (%.3f, %.3f)", offset.x / uor, offset.y / uor);
mdlDialog_dmsgsPrint(wStr);
