[Discussion] A different approach to Arch modelling (Arch Assembly?)

Going back to my third post in this forum to show how stubborn I can be

I have exactly the same plan as yours BTW, arch sections can already have 2D objects. I also plan to extend the BuildingPart to have an implicit, “embedded” section plane. So you would basically have three objects to work with, to deal with views:

• Section planes: do not contain objects, define a 3D view (not yet), define a 2D view
• Building parts: contain objects, define a 3D view, define a 2D view (not yet)
• WP Proxies:do not contain objects, define a 3D view, do not define a 2D view

I made a bit of an experiment on the same concept using the same base object we used with the wall prototype:

This would allow to separate the Tree into a model part and a documentation part, in my opinion improving a lot the structure readability. A user will be able to activate the view automagically:

• aligning the 3dview,
• activating the WorkingPlaneProxy
• activating an embedded shape2dView producing the section cut.
• enabling CutView property to show the effective model.
• will we use it to filter objects by type too!?
  When the view is moved, all the contained documentation objects are moved accordingly!
  What do you think?

Edit: Little improvement! when activated the section plane shows it’s childrens, set the section plane, align the view and activate the clipping plane (for autogroup integration, I should study more the BuildingPart class).
