View Full Version : 2020 Override Visibilty Graphics - Halftone Existing Phased Elements of Linked Models

Hi,

As the title suggests I am hoping there is a way to achieve overrides (specifically halftone) of existing phased elements of linked models. I'm doing a heritage restoration/redevelopment project comprising of four linked models and would like attention to be drawn to new construction elements while also showcasing the heritage features of existing (elevations only).

I know how to achieve this effect in a normal situation of an individual model, however I am unable to follow the same process for linked models within a host model. I know that I can override the entire linked model in 'Visibility/Graphics' --> 'Revit Links' --> 'Halftone', although I would like the new construction of each linked model to remain in 'fulltone' so to speak.

I'm sure there would likely be a better practice to achieve the effect I am referring to, although my usual process in any given view is to --> Set the Phase Filter 'Show Complete' & Phase 'Existing' --> I then marquee the entire Existing elements --> right click mouse --> Override Graphics in View 'By Element' --> Check halftone box & click OK --> Change Phasing to Phase Filter 'Show Complete' & Phase 'New Construction', allowing the new elements to remain unaffected by the override.

Trying to Override Graphics of the linked model will only let me override 'Category' and not allow 'Element' overrides. So for example: when applying the override by category, the new stairs & existing stairs are unable to be filtered or differentiated by their phase.

I should also mention that I am predominantly using Revit LT although do have access to the full version. I realise my issue could also be due the certain limitations of LT. I have attached a screenshot of the model without halftone overrides and also an example of the desired effect from a previous project. Thanks in advance for any advice.

If the elements where somehow in a separate linked models your problems would be solved of course. Interesting and understandable request. I was thinking worksets at first but ran into a dead end. I'm pretty sure it can be done with dynamo but that's not exactly readily available. It's tedious but you can use the Linework tool to enhance lines through a linked model so that can be used in a couple ways.. Whether or not you use the halftone for the link will depend on the results.

Are you using Phase Mapping for each linked file (https://knowledge.autodesk.com/support/revit-products/learn-explore/caas/CloudHelp/cloudhelp/2020/ENU/Revit-Collaborate/files/GUID-97E3F329-B78A-4854-841D-CDE2EAA1FD73-htm.html #RevitProducts) (a parameter of each link)? This is how Revit understands the phases of those files. For graphic overrides to extend to the links properly you must use exactly the same Phases (naming) and Phase Filters (naming exactly) in all of the files. If any of the Phase Filters do not match exactly the graphics won't work.

Hi Steve,

Thanks for the reply. If my desired outcome is achievable I must be missing something. Linked model phases are all matching Host model phases. All Links' Display Settings are set to 'Host View'. See attached images (apologies for the poor quality screenshots). When I select a link to override it's graphics, I am only able to select 'By Category'. 'By Element' is greyed out. The only work around I can think of would be extremely tedious....

1. By adding a common shared parameter (comment such as: 'halftone existing') to each element in linked views that I want control over.
2. Create a filter in the Host model referring to the comment.
3. Override 'By Filter' in each view.

Please tell me there is an easier way. I just can't grasp why I'm able to hide individual elements within linked models, without having the ability to override individual elements in linked models.

Override Graphics in View is not available for linked elements. Only the Hide In View feature is. The linked file's elements should adhere to the same graphic overrides for the Phase Filters of your host project if the mapping is done. That means you shouldn't have to do anything to override elements if existing elements in a link are assigned to the correct phase, the same as the existing elements as the host model.

Alternatively you'll have to consider configuring views in the linked file so you can use the Linked File override > By Linked View via Visibility/Graphics.

That's great! Thank you. It was something very simple I was missing. The functionality to override phases rather than elements. I can't believe I haven't used this feature before.

So I've now got the halftone override for existing elements. My only issue now is that the phase filter override is in effect in every view i.e. Elevations & Layouts. Is there another setting to apply phase filter override to elevation views only? I would like to show existing, new & demolished phases on floor plans in full tone.

You need a dedicated view for each purpose.

Each view has a Phase and Phase Filter parameter. Each kind of view you need has to assign the correct Phase Filter. A demolition plan usually uses Show Previous and Demo. A plan showing new work would use Show Previous and New. If you need to show all the work together without a difference between existing and new then the Phase Filter Show Complete will do that.

That's assuming default configurations for Phase Filters. Each filter allows you to define the four phase "states", New, Existing, Temporary and Demolished. Those can be By Category (Object Styles and Visibility/Graphics), Overridden (uses Phase Graphic Overrides) or Not Displayed (won't be visible in the view).
