When I step through all the materials, one at a time, I can get all info from them. However, when I step through the geometry from the 3D-Window, I get some "iumat" short that should be an index into the materials.

char matBuffer[64]; material = component.pgon.iumat; API_Component3D component3D; component3D.header.typeID = API_UmatID; component3D.header.index = material; err = ACAPI_3D_GetComponent(&component3D); if (err == NoError) { API_UmatType umatType = component3D.umat; sprintf(matBuffer, "%s", umatType.mater.head.name); }Now I get the correct material from a 3D Polygon...

It seems the the "Attribute" Material and the "3DComponent" Material are reached in a complete different way!
