PEMB Roof Ridge - How to Move

ahannerX5E95 — Mon, 17 Jan 2022 15:57:49 GMT

This Pre-Engineered Metal Building has (4) different eave heights, and I have not been able to adjust the location of the Ridge for the roof.

I tried creating 2 roofs and connect them at the ridge, but then they did not end up at the same elevation at the peak, and if I aligned them, then the slope changed.

I am able to select the ridge line, but I get an error that the element cannot be moved.

I tried making it completely flat to manually add a ridge line, but this did not work well, also.

Does anyone have any other suggestions? Preemptive thank you for any help.

Got pictures?

Or Post the RVT so can see and explain how to approach.

Here's a little context: (slope is set to 3/8" / 12")

Offset From Roof Base on one side will move the Ridge.

Is there a way to see that option in my Properties Palette? I don't have that option, but that looks like that is exactly what I'd need. (I'm in '22)

I misunderstood, I thought that option adjusts the eave height?

That's exactly what's happening if the pitch is the same on both sides - but the Ridge is not in the center.

You could sketch this way. Note where the Define Slope Symbols are at on each side.

So far I have:

Set the roof level at the lowest eave height

Offset from Roof Base the difference to get the correct eave height

Set the slope/pitch on the longest roof edges

Is there a different approach to achieve a specific eave height and also control the ridge location?

Thank you for the help.

Thank you for the quick reply, I will try that now and report back.

Think about it. If both opposing sides have exactly the same pitch, how can they meet any place but the center point between?

Try doing the Roof in Elevation using Roof by Extrusion method. You'll see what I mean.

Thank you for the help.

To control the exact ridge location, draw the roof normally with the same eave elevation, move it the ridge is exactly where you want, finish the roof, then use Vertical Cut opening to cut the eave(s).

@ToanDN that is an interesting approach, I will try that suggestion, too, but the @barthbradley suggestion worked for the achieving the correct ridge location. I am checking the eave heights and reattaching to the roof, but I am receiving errors that the columns cannot attach to a non-structural element. I will keep at it, though.

Thanks to you both, I think I may be able to work with what I have for now for the LOD the project is asking.
