There has been a unique, unexpected challenge that I, as a BIM Coordinator, have had to to perform over the course of each project.. There is always some part of the project where Scope Gap occurs & the BIM Coordinator or General Contractor has to be creative or fill in the gaps so that the project can can move forward. This is one of those instances.
I'm doing BIM Coordination on a project that has a complex woodwork package around an auditorium. The BIM Coordination team has been tasked with modeling & coordinating with a the wood work, which requires pinpoint accuracy & almost zero-construction tolerance. During coordination, my woodworking contractor discovered that the Design Intent (DI) model included some parts of their scope, and they needed it removed from the DI model in order to fully coordinate & build their model.
I agreed to take on the challenge of solving this issue, thinking it would be simple (I should've known better - I'm not a Revit expert). I first tried to edit the structure of the walls by just deleting the pieces & parts of the wall I didn't want. I edited the Wall Type & then omitted the structures I didn't need. I saved & applied & was horrified by what I saw - the walls were all out of whack because each wall had a different Location Line setting.
I could edit each wall & place them all back one by one or I could come up with another solution. I tried a bunch of other things: creating wall schedules & editing each type within the schedule, turning off wall types in Visibility Graphics, and a couple of other things. I was stuck, so I went searching on the internet, and discussed the issue with some colleagues, and finally came upon a solution.
How to hide specific parts of an Element, Object or Assembly:
- Open your Revit file. Duplicate or create a new view & rename it. In the view, hide all elements except for Parts & the elements you want to modify.
- Select all of the objects you want to edit. In the Modify Tab, click the Create Parts tab.
- This will break your objects into individual parts. Next, hit Edit on your Visibility/Graphics Overrides in your Properties Tab.
- Select the Filters tab & then hit the "Edit/New" button.
- When the Filters window opens, hit the "New Filter" button on the bottom left. In the Categories portion (middle) select only "Parts." Then in the Filter Rules, select the property & name you want to filter.
- Hit Apply, then Save, then Add the Filter to your Overrides. Don't forget to uncheck the Visibility box & then save. Your parts have been filtered out of view.
- Repeat steps 1-7 until you have filtered all desired items out of view.
There are a few things to take from this process. The first is that the answer to your problem is out there, you just have to find it. I learned how to hide elements using Filters & the Create Parts button because of Trial & Error, Research on the Internet & discussions with other Team Members. The second lesson is that your job as a BIM Coordinator is going to challenge you to step outside of your comfort zone & do something new. Embrace that knowledge, learn from it, and become a better BIM Coordinator because of it. Now you have another tool to put on your belt.
