Mullion profile visibility based on view detail level

Anonymous — Mon, 17 Feb 2020 07:53:32 GMT

Hi everybody,

Does anybody know if the (actual 3d) mullion profile can be hidden depending on detail level?

I have the typical situation where I want to show a very simple rectangular outline at course level and a more detailed section (2d family nested in the mullion profile family) at medium and high level of detail. I've tried to find some visibility options within the profile family, I've even tried to add a visibility parameter to the lines of the profiles but I had no success. That can't even be achieved changing the VG settings of the model as that will affect the whole profile (2d info included).

Any suggestions?

You can hide mullions in view by selecting hide elements in view or using view filter.

If you want to show a different profile in different views I think you could try using design options (or phasing):

I wouldn't want to hide elements manually and if I try to use VG settings it'd hide the whole thing (as the 2d info is nested within the profile family). I haven't tried with filters... how do I need to set that up?

Re: design options that's something I'd like to avoid to be honest.

Create (or edit) a profile and set its usage to mullion. Draw a profile of the detail and set its visibility settings to only show for fine detail. Then draw your rough profile and set its visibility settings to only show in course and medium.

That's exactly what I've done. The problem is that the profile drawn in the family of the actual mullion profile is always visible, no matter the detail level settings I choose within the family. See images attached.

Are you sure it's the profile showing and not the extrusions for the adjoining mullions? Try setting those to continuous aligned to your view (hor/vert?)

Maybe you can use cw panels if you model it using panels only… or i'm not understanding the profile question perhaps.

Then you might have something like this, but it's quite a bit of effort making that work I suppose.

Just create detail components of the detailed profile and place them in detail views, then hide the mullions category.

That's probably better:D. You could use a line-based family with detail item and actually just pick/draw lines on your curtain wall for mullions, even align/lock them to it.

Well.. that's exactly what I wanted to avoid. It'd be good if I could have both the mullion profile and the detailed 2d info in the same family and switch those on and off depending on the level of detail I set for the view. However that seems impossibile to achieve. What I am not getting is why Revit does allow me to set the VG for the mullion profile and even if I specify I want the profile visible only at course level it still shows up at medium and high level. That buggers me!

If you use masking regions in the Detail components to hide the 3D profile drawn in the Profile Family, you will have something similar to the below.

I usually model the 3D profile to suite the section I want to see in Medium Detail View, the in the Detail component

(COARSE) Add a rectangular masking region with a border to show a simple rectangle
(MEDIUM) Add a second masking region with boundaries similar to the 3D Profile to hide it exactly (used also in fine) + A simple border also matching the 3D profile
(FINE) Use same masking region from step 2 + 2D Cad details received from manufacturer

The nested the detail component should be set to be visible in all coarse/medium/fine (in the Profile Family)

Those are some nice mullions, but that doesn't affect "the (actual 3d) mullion profile"... I still think design options could be interesting although curtain walls can be a little difficult with that, or as mentioned before otherwise it's not possible unfortunately.

RDAOU — Tue, 18 Feb 2020 13:32:05 GMT

Maybe I misunderstood something but the recent replies are discussing Profile + Detail Components => 1x3D + Multiple 2D...where the 3D element is place holder and the 2D Components reflect the different detail levels of that profile based on the view setting (Coarse Medium Fine) - Swapping 3 different 3D profiles or in other words having a Coarse/Medium/Fine versions of the same 3D element doesn't really make sense. The detail level of the 3D element is modeled based on the LOD specified. You model ONE 3D profile that meets that spec not 3x 3D profiles each for a different detail.

Design option => present different designs => then select one.

If the intent if to present diferent Curtian Wall Systems or different finishes, then for sure that is the way to go. Otherwise, sure one can exploit DO to have the same curtain wall with the same profiles modeled in 3 detailed levels placed 3 times in the project, but what for what purpose would that be? to do the work 3 times in 3D and bloat the model more than it really needs to be? who knows, maybe that's the way to go

nesting a mullion profile into another isn't possible

This is what I call "a proper explanation". Many thanks @RDAOU

I just have one question regarding the process you've described. Why do you need to create a masking region for the COURSE scale? Is it not sufficient to simply draw the outline of the mullion profile, which is part of the profile family anyway? I then get the point about adding a masking region for the MEDIUM scale as you are showing with the grey hatch in the video and obviously the CAD info from the manufacturer for the FINE scale. But I don't get why you'd need a masking region also for the COURSE view...

To recap, in terms of families I need to use, would it be as listed below?

1 x mullion profile

1 x detail item > masking region COURSE - or maybe not (see query above)

1 x detail item > masking region MEDIUM

1 x detail item > masking region + cad info (imported?!) FINE

Once loaded all the above families in to the main profile family I'll then edit their VG settings (course / medium / fine). Is that correct?

With your suggestion to use a masking region to hide the actual profile in COURSE scale (if needed), do you confirm that it isn't possible to hide the actual profile no matter the VG settings we input within the profile family? Am I getting it right?

If you take a second look at the plan view, you will notice that I have set up 1 profile to have 5 different 2D sections/variations. I use one curtain wall profile per system.

The reason I did that is because at the early stage of design, one may be able to decide what system to use, but one wouldn't know exactly which section/dimension to use until it the facade engineers finish their calculations at a later stage. Therefor, I mask the 3D in all plan views and use the 2D components instead allowing me to pick whichever section of the five nested there in.

I am currently not at my desk but I will forward you the profile later in the afternoon when I'm back and you can test how it works. But do note it was produced for a class I gave back in 2016 using educational version...so you might need to reproduce it if you are going to use for commercial use.

Hi @RDAOU

Sorry for the late reply but I've been away for work.

I completely understand the principle you've described. You simply don't want the 3d profile to be shown until the final design (shape and size) is defined by the facade engineers. Makes sense!

What have you done in order to achieve that? Have you simply loaded in to the profile family X number (5 in your case) 2d detail item families and created visibility parameter to be then applied to each one of them? Doing so once you are in the main model you can switch between different types of 2d profile. Is that correct?

If you could share the profile family that would be much appreciated. Thanks in advance for your help!

I think, at least for me, the original question was about setting up different 3D mullions by LOD.

And I am afraid there is no answer to make a mullion's visibility to vary by Level of Detail.

So that we can have a Coarse mullion as a simple box, for elevation drawings, and a fully detailed profile for renderings, for example.

One possible request would be to allow multiple loops in the mullion profile, and set their visibility by LoD, which we can actually do right now, but which you cannot then load into the project...

Thank you

I've been bothered by the same question. I don't think there is a 'clean' way to have the profile line hidden with fine detail level but shown with course or medium detail level in the view. My work around is: in VG or the corresponding view template, set the curtain wall mullion category cut line color to be white and weight to be 2 to make the profile lines 'hidden'.
