Rectangular ducts - wrong dimensions

[francesca.duffizi]

Hi, I get an issue working with rectangular ducts. I set the correct size on a plan view, it's correct in sections (cut duct) but INCORRECT when duct is not cut! Width and height are reversed and the tags are completely a mess!

When I select an object in the section view I can see the right values for Width and Heigth, and Dimension in the Properties, but at the same time I get reversed values in the option bar...and the tag (which is referencing the Dimension parameter) is wrong!

It is insane...how can a parametric software have this kind of bugs?

Has anyone a solution for this issue? I don't think having a double tag is an acceptable solution...

Below is a basic sample, tags are referencing the Dimension parameter; the correct view is the plan, showing the real situation with correct tags... every section has a bug.

But why are you speaking of opinion? it's a fact.
In section views, values are inverted and occurs in revit errors. Try it, you will understand what we are saying.

Look at that, duct 1000x500h, section view:

Handles are ok.

Now I just click on it, and revit is inverting them and trying to make it 500x1000h:

In option bar, width and height are still ok (french Largeur is for width):

It is mixing plan and section views logic.

Or everything has to be consider like a plan view and width is becoming height (it's non sense but it can be logical is everything is going the same way), or in section view, width is always width, no matter the point of view (and option bar has to change).

And it's really a pain to go through this bar everytime to invert values (and tab is not working...)

You call it a bug. That is not a fact. It's more like a lack of understanding on the part of the user.

OK nervermind... i just showed you, but you didn't read.

[RobDraw]

I already knew what you are talking about. 

I disagree with your analysis of it being a bug.

Duct Placeholder est une fonction essentielle. Il n'y a pas de famille à partager.

Duct Placeholder is a core function.  There is no family to share.

Hi,

I had made the request on Revit Ideas in 2016 to have a button that would swap the dimensions of a rectangular duct but without success... The law of the vote !

Hi
I got an explicit exemple of the issue you don't want to call a bug:
I got a vertical duct, and i want to change its dimensions to 400x200h for exemple.

I tabbed (? from tabulation) the duct to select it all, changed the value and this is what Revit made:

It inserted a fitting because it inverted width and height when going from vertical to horizontal. It doesn't know what is a height and a width.

Don't call it a bug if you want, but definitely it's not the way it has to be.

[RobDraw]

It's a matter of perspective. If you want to call it a bug, go ahead. It doesn't change anything. 

[fruity101079]

I just prove you the issue with another concrete case, how can you can't see it?
But yes, it doesn't change anything, there is a problem, and it's a pain to draw ducts...

I've seen this happen when there's several rise/drop sections in a duct, as well as when you using automatic routing. The direction the duct is drawn is based on the starting section and is what sets the original height and width. So if you have two sections - for example, add on duct at an elevation drawing "left to right", and another (and in some cases at a different elevation) from "right to left", it gets disoriented. 

I've used the same solution and used the combined duct size parameter to show the size, but be aware - what's "height" to me may not be the same, especially when working vertically.

thanks - db

You didn't show me anything that I didn't already know. Your opinion of what to call it doesn't mean a thing. It is what it is. We're all aware of it and most can adjust their workflow so that it doesn't matter.

Good luck.

Provide us the ability to redefine the top of duct (or some datum). Better yet, have dimensions on plan always be width x height.

Below I have ducts tagged with the same dimensions however one has been rotated which causes it to dimension incorrect. The one on the left should read 850x550. 

[RSomppi]

You can make it read the way you want. Change the width and height in the properties of the duct and rotate it. Plan for this quirk in the future as I don't think it will go away.

If you think it should be a new feature, suggest it in the Ideas forum. I'd be willing to bet that it ahs been suggested before. It might be better to vote up a previous thread than create a new one.
