Assume two attributes, Heavy montreal and Heavy montreal click are defined. Heavy montreal is a text attribute and Heavy montreal click is also a text attribute defined with a Button as shown below:
The configuration above means that when the attribute page for the document is loaded in WebCenter, the attribute Heavy montreal click will be evaluated and it will be set to the value in the attribute Heavy montreal.
Assume an ArtiosCAD user saves a document and saves its attributes as shown below:
So while the WebCenter form is still open but not saved, the attribute values will be different than what the ArtiosCAD user sees at the same point in time. When the WebCenter form is saved and the document is next opened in ArtiosCAD, the attributes values will be the same.
