Cross Section

[dsw98]

I've started with my first Cross Section in Revit. I'm looking for suggestion on how to attack this as far as labeling and details are concerned. I.E. showing walls on top of floors and foundation walls. Showing top and bottom plates ect. Showing how the siding will overlap the foundation wall. Is it just easier to create a seperate callout for specific sections? I know this might seem pretty vague. I'm just trying to zero in on what I should do, Thanks.

I use a stacked wall to create a foundation and footing. Then imeadatly on top of that aligned at teh exterior core the exterior walls. Your floor when you draw it, after all the walls are done will be drawn be selecting the (exterior) face of core. The program will them prompt you to cut the walls w/ the floor and you select yes. Now, the floor should be high enough above the foundation to leave the thickness of your plate. Then add a detail component for the plates and insulation etc. as needed. There is one thing that bugs me you have to use linework to make the interior finish invisible (by dragging the grip) under the floor (or add a white filled region w/ invisible lines as edges if you have a fill pattern to hide in the finish as well.

Okay so even with all the great detail a cross section automaticly creates, I'm still going to have to add other detail Items. One thing I'm still having a hard time with is the cross section of my roof. What's the best way to show the cross section of a Truss, just take what Revit creates?

Is it possible to close a door in a cross section few but have it open in a plan view?

[Dean Camlin]

Doors will normally be shown closed in elevation and section views but open in plan views. This is due to how their visibility is assigned in the family: the projected lines of solid objects (such as the door panel) are defined as visible in elevation & 3D views but invisible in plans, while the symbolic lines of the open door and its swing are defined as visible in plan but invisible in elevation & 3D views.

Roofs in Revit are modeled as if built with rafters following the roof slope. To model a truss bottom chord you would probably want to insert a separate compound ceiling, then add detail lines depicting the web members in any cross sections. This is one topic in the program that IMHO could use some improvement.

Here's what I am also looking to do with a roof, not sure if it's possible. I need the tails of the Truss to over hang like in the Cross section 1. Cross section 2 is what I currently have. Is Cross section 1 possible with Revit. Can I create a roof that does this overhang?

P.S. you'l have to rotate cross section 1. I hate how the PDF rotates on it's own

[Dean Camlin]

The answer is yes. You can define the roof to have an overhang and change the roof properties so the edge comes down below the bearing point, then model a soffit to close up the overhang. I'm sorry I don't have time to write out a blow-by-blow description. Please complete the roof tutorials and experiment some.

Okay, I've been looking in the Tutorials but can't seem to find the right one. Can someone point me in the right direction?

Use the pick wall option for truss roof by footprint with defined overhang.
