Autodesk ObjectARX

[#1]

Hi all,

I have some questions about AutoCAD material library here.

1. From which AutoCAD marketing version has AutoCAD supported the consistent material library?

2. Does there have some special APIs in RealDWG & ObjectARX that support it?

I am trying to retrieve AutoCAD consistent material and convert it for other products? So could anyone help answer the two questions? Thanks in advance.
