Elevation phase filter

[santamartabonito]

Hello,

I'm doing an alteration project in which a large part of the building is demolished, but it turns out that when I see changes in elevation, graphically, the new construction is covering the demolitions.


Does anyone know how to "turn off" the masking of the new construction phase?
Or change the Phase Graphic Overrides settings so that the demolitions also appear, as in this image (this image was combined in photoshop)



I also send a test file as an attachment.

Thanks!

you can try override graphics in view > by element > change surface transparency value? and see if helps. thanks

[santamartabonito]

Thanks for the reply.

Yes, this works in some situations, but it would have to be applied element by element, which makes a very complex process in large projects or with a lot of detail.

There is also another problem, if between the demolition and the wall that is covering it there are other elements, for example interior walls, those walls would also appear with the transparency of the exterior wall.

I use a similar process for floor plans, I have a view template where I hide all the wall cut patterns, and then I limit the view range so that the lower floors do not appear

create views for Existing and set the Phase Filter to show All

duplicate that view change the phase of that view to New, change the phase filter to Show previous and New

assign all to be demolished in "NEW" Phase in the Existing View.

Duplicate the view and name it DEMO set the phase to New and the phase filter to show Existing and Demo

you end up with 3 views each showing the respective graphic by phase

this should help seeing if there are any errors in your views

No sample model was attached.

[santamartabonito]

Sorry, there must have been an error attaching the file.
Here it is.

What I initially thought was something similar, create 2 views with the representation I want (by the way, that's what I did in the assembly, I created two views and combined them in photoshop) and then put one on top of the other.

The problem is that the view at the front will mask the bellow view, so it will end up doing the same problem.

[RDAOU]

Well since the demolished wall is concealed behind the new/proposed one, overlaying on a sheet would be the most practical.

View 1 ... what you have already in the model
View 2 ... isolate the demolished wall and windows (ie: show only demo) + add a filter to overide wall surface pattern to transparent

Overlay pn a sheet


Alternative, you could try to work with revealing hiddem elements

What is the purpose of showing New Construction and Demolition in the same view?

[santamartabonito]

In renovations, we use these drawings for licensing purpose, are part of the licensing project, to be approved by all legal entities.
See the following example.

Do you have a similar example for elevations?

[ennujozlagam]

what we did in the office we make a demolition works as a autocad file (plans, elevations, sections, colour yellow/hidden..etc) and link them into revit for easy manipulation and if we are going to submit to authorities, all the cad links we make them as import as separate file for submission. authorities don't bother if you model (revit) or not  it as long as they can see where are the demolition works and new ones.

[santamartabonito]

Sure, here is an example

[santamartabonito]

Yes, it's a way of doing it (what I sometimes do is export the view to AutoCAD, work on the changes and re-link it in Revit) but it's actually duplicating work, and if the design is changed, you will have to redo the changes in two different files.

This should be a relatively simple option in Revit, of turning off the masking of the walls, that would be enough to make it work.

[santamartabonito]

I also thought about this hypothesis, but the problem is that if the surface pattern is set to transparent,  then the interior lines of that view, will also be visible, for example interior walls.

I wonder if there is an addin, or something similar, that can remove the opacity of the views and just show the lines?

[RDAOU]

@santamartabonito 

I do not know of any addins that does that. Removing the opacity of a wall would show you all the hidden elements/lines behind it so that would not really be the same as what you showed in the latest images you have posted, which looks somewhat arbitrary...

• Sometimes walls mask what is behind and sometimes not (existing seem to mask all what is behind)
• Sometimes you seem to keep surface patterns of both demo and new and sometimes you seem to remove it 

Such things cannot but be done manually. 

You could potentially use Dynamo instead of Autocad... 

• Create 3 Elevations view (1 existing, 1 New and 1 Demo)
• Use Dynamo to convert the New and Demo Elevation views to Drafting Views (ie: these will become lines)
• Overlay the above 3 on sheet (the existing being the model view will be in the background and the New / Demo Drafting Lines on top

[santamartabonito]

Thanks for the suggestion, I'm not into Dynamo, but it might be something to explore.

However, I managed to find a way to do what I want, it doesn't seem like a valid solution, but it's something...

The steps were:

- create two views, one with the existing (black) + demo (yellow) the other with the existing (black) + new construction (red)

- overlap the two views

- assign a different disciple, other than Architecture, to one of them

- change the halftone underlay brightness setting to 100


This way I get the result I want, however the underlay/halftone settings will impact all views, I don't think I can change these settings just for a specific view.

@santamartabonito 

That was what was suggested in the previous reply...However, you do not need to Change discipline to make an elevation Half Tone...On the properties Pallet you can set Model Display to Half tone

[santamartabonito]

That is correct, you can change the Display model parameter to halftone, however, this option will keep the lines of the view that is underneath blocked, I was only able to overcome this by changing the discipline of the view that is above.
