“information can be provided to the material by linking to a seperately defined property set (by Property Set), or can be input directly into the material (Independent). This allows several materials to share a single set of properties and changes to that property set to propagate to all those materials.“
Also from the WikiHelp on this subject: Each material can have two types of properties referred to as aspects: appearance and structural. You can store appearance and structural property sets in their own library. Appearance property libraries adhere to the Autodesk standard Protein format and have the following file extension: .adsklib. Structural property libraries are written in an XML format and have the following file extension: .adstlib.
When a user appearance property set library is loaded, it is always available in the Materials dialog. Structural user libraries are available per project. They will not load unless you specifically load them into a project.
Autodesk is offering a free upgrade to Autodesk Building Design Suite Premium. I just got off the phone from our reseller (KarelCAD) and those who currently hold one of the Revit Suite subscription licenses (RAC Suite, RMEP Suite, RST Suite) qualify for this free upgrade.
According to our reseller, this is a limited time promotion for 2 months.
I’m unsure if it is going to be rolled out globally, or if it is just limited to Australia.
Here is the only catch – if you accept this free upgrade, your subscription cost will increase. In our case, it will be an additional $375 (ex GST) per license per year. In real terms, I guess it will take quite a few years of paying this increased subscription to actually ‘break even’ with how much it would have cost to buy 3ds Max outright.
Something that isn’t mentioned here is monopolization. At times we feel that an all-in-one Design/BIM/Documentation/Presentation tool would be awesome. But where is the competition? If we all end up using one powerful piece of software (ie. Windows), who makes the developer accountable?
Scenario You are an active Subscription Customer and have upgraded to an Autodesk Design & Creation Suite, and would like to download a previous release of the Suite, or one of Autodesk software components within the Suite.
