Many PTC customers require CAD data from their (end-)customers for the development of their products. Examples for PTC customers: * Manufacturers of automation solutions for machine tools in metal cutting * manufacturer of components and systems in aluminum die casting * Manufacturer of complete interior solutions for rail vehicles ... The CAD data provided by the end-customers are usually very extensive. PTC customers load them into Creo Parametric and save them in Windchill. In many cases, the data provided is more extensive than the data of the product to be developed.
The engineer creates a huge amount of EPMDoc objects and structures that he does not actually need, but which often require a lot of administration. The engineer only needs the geometric representation, but not the objects and structures.
In PTC´s Creo Elements/Direct product range, the concept of "inseparable assemblies" is available for Modeling (CAD) and Model Manager (PDM). An inseparable assembly acts like a zip file, containing all 3D geometry files.
In CAD (Modeling) the CAD structures are visible, but not in PDM (Model Manager), where an inseparable assembly is just one single CAD data entry (equivalent to a Windchill EPMDoc).
An "inseparable assemblies" concept for Creo Paramtric and WIndchill would be of great benefit to PTC customers.
