Duct and Pipe Rise in Reflected Ceiling Plan

[Anonymous]

Posted this in REVIT Architecture and didn't get a response, thought I
would try it here.

We are having an issue with duct and pipe rises in an architectural
ceiling plan view. (Our engineer's model is linked into our model) If
the riser is within our primary view range, but above the ceiling, it
still shows up (as if it goes below the ceiling), even in hidden line
mode. The ceilings are not overridden in any form to show as
transparent. It is as if the riser ignore the fact that anything is
between it and the cut plane.

For example, we have an 8' ceiling. The view range for this ceiling
plan is set so the cut plane is at 7'-6" (above associated floor) and
the top and view depth are both set to 12' (above associated floor).
If there is a riser that happens from 9' to 11', then it shows up on
the ceiling plan as if it were below the ceiling. Since there is a
ceiling between the cut plan and the riser, we should not see the
riser. If we lower the view range below the riser, then the riser
does not appear. But many times we need the view depth to be higher
because of different ceiling heights.

Anyone encountered this before? Any solutions? Is this a bug in
REVIT? Thanks!

Am I reading this right?

Top = 12'
Cut Plane = 7' 6"
Bottom = 12"

Riser = 9' to 11'

The riser is within the view range, therefore you can see it.
This is correct operation as far as I understand it.

Can you also see the horizontal ductwork associated with the riser? (If there is any)


When you say 'ceiling plan' do you mean reflected ceiling plan? If so, what do you have 'underlay' and 'underlay orientation' set to?

Possible solutions are to use a reflected ceiling plan (if you are not already). Or experiment with plan regions. I understand these can be used to make what is in effect a variable view range, but I havent actually used one yet.

Yes, this is on a reflected ceiling plan. The riser is within the
view, but it should not be visible because it is above the ceiling.
Horizontal ductwork is associated with the riser, but it is correctly
hidden by the ceiling.

Hmmn, you're right. I take it all back lol.

When I tested it in MEP the same thing happened.

If I set:
Underlay = Ground floor ceiling
Underlay orientation = Reflected Ceiling plan

View Range
Top = just below ceiling
Cut plane = just above floor
Bottom (greyed out = cut plane)
View Depth = cuts or above riser

Then it displays ok (without the riser showing) on my screen.
Does that work for you in R-arch?

If you didn't follow all that, the short answer is;
Lower the top view range to below ceiling level & leave your other settings as they are.

I couldn't say whether working like that is a bug or a feature 😛

That is what we ended up doing for the one project, but we often have
projects with ceilings at different heights. It won't work for those
projects. Then we would have to go around and individually hide in
view. A real pain. Sounds like I need to request a bug fix from
AutoDesk. Who knows whether that will do any good though.

Thanks for the confirmation.

You could also use plan regions, they have their own view range.

What I did, was have the Underlay set to none, Underlay Orientation to Reflected Ceiling, and Displine to Mechanical.
