As many know Revit Structure implemented some features that the Architects have highly desired in Revit Architecture. These features are Curved Beams, Slanted Columns, Beam system Tags, Beam Coping, Metal deck, and Truss. Feedback has been consistent. (If you want to reiterate past comments please send them here) I've been investigating specific architecture requirements (if any) for these features and would like to quickly review and solicit feedback on a particular feature in this post: Metal deck representation in floors.
Behavior in Revit Structure
First I'll review the feature in Structure for those unfamiliar.
Floors have a layer function "Structural Deck" where a 2D profile family can be specified to represent metal deck in section views that are set to a "medium" or "fine" level of detail.
There is also "Span Direction" symbol that documents the direction and allows the user to manipulate it. The symbol is placed automatically and if one is not present you are prompted to load one. There is also an "Align Perpendicular" contextual command that allows the user to align the deck to a slab edge when a Span direction symbol is selected.
Section View Behavior
Floor sketch lines also have a "Concrete Cantilever" and "Steel Cantilever" properties. These control the slab edge condition.
ValidationI am looking for feedback on the following two items:
- Assumption: Architects are interested in the 2D deck representation in sections but not necessarily the span direction symbol that Revit Structure requires to control the span direction in plan views. Is there any need for the default span direction symbol if another method is available to control the direction?
- There are some examples where architects show metal deck a single way (corrugated orientation) regardless of the true direction. Is this just an old convention or is there a true need to document the deck this way? I ask as it violates the idea of the drawing being an accurate representation of the model.
In addition to dialog on the above two items other comments related to the feature description are welcome.
