When looking over the state of any feature in Revit it can often lead to a trip down the proverbial "Rabbit Hole". So far on the topic of selection I have covered Press & Drag, and touched on Chain select. In this post I want to get some feedback on Underlay and Links with respect to selection.
Underlay has always been slightly out of alignment with user mental models. In 2D processes underlay had one drawing placed under the other yet in Revit we are looking deeper into the model at parallel levels - not placing one view under the other. Further there is the additional behavior that underlays are open for selection which is also often unexpected.
This can come in handy when using Linework to reference items above yet can also cause accidental changes do to inadvertant selection. You may note that the system currently prevents box selection from working on anything visible via the underlay and this was implemented after receiving user feedback.
My question to everyone is when is selection of an underlay useful? MEP workflows or reading property values? What if underlays were never selectable? Is the work around OK?
Another potential mitigation strategy would be to allow underlays to be selectable in specific tools, such as the Component or Linework tool, yet disallow selection for the Modify (Arrow) tool.
I'm very curious to hear your thoughts.
Much like underlay when is the selectability of a Link a problem and when is it advantageous? Specific examples can help us acheive the best default behavior and/or allow flexibity if required.
