Spotted this one yesterday. In Vasari, if you divide a surface & select the divided surface with a view to changing the Surface Representation, there is no arrow to the Surface Representation options dialogue.This is Vasari…. see..no arrow? No dialogue…no Nodes… :-(
This is the same thing in Revit 2012….arrow to access the Surface Representation options.
I thought I was going mad! Fortunately Zach K. put my mind at rest & confirmed it as an interface bug. The arrow is there, see the image below, but its hidden at the end!
