RealDWG does not support write to R13 and lower versions?

[alanchen123]

I am trying to write a DWG file in R13 format, like this:

if (m_pDb->saveAs(strFileName, false, AcDb::kDHL_1012) != Acad::eOk)

  return FALSE;

but the saveAs function will not return eOk. If I change AcDb::kDHL_1012 to AcDb::kDHL_1014(R14), then it will return eOk.

So RealDWG does not support to write to R13 and lower format? I am using RealdDWG 2014.

Thanks

That's correct, neither RealDWG 2014 nor AutoCAD 2014 will write to R13 or earlier DWG format.
