Nice tip + addin coming from Trevor Taylor via Jeremy Tammik – it shows how to rename Interior Elevation views by the Room that they reside in.
Download: Here is a complete sample project including a test model in case you’d like to check it out yourself. Many thanks to Trevor for this useful tool, his research, implementation, and generous sharing.
You can use the Wall Opening tool to allow Revit Room elements to flow between spaces. Other methods are not very reliable or just will not work. So, don’t forget about this little button on the Ribbon:
“the room calculation point specifies which space the air terminal is in, it is … reflected in schedules. For example, if you include a column in the schedule with Space data, such as name and number, the space dictated by the room calculation point will be used. “
Here is the problem – I have two linked files, set as separate options in the same Option Set. If any of the Room elements overlap in the two linked files when placed in the host file, and I have the view set to a Secondary option, the Room Tag fails: None of the created elements are visible in Floor Plan: UPPER FLOOR PLAN – Option 2 View. You may want to check the active view, its Parameters, and Visibility settings, as well as any Plan Regions and their settings.
If I move the link in the secondary option AWAY (geographically) from the link in the primary option, the Room Tags work fine.
The workaround that I am currently using is this:
Place the two link files in different Option SETS. In this way, both the Revit links can be a ‘primary option’.
Make a ‘blank’ option in each of the Option Sets.
In a plan view, set the Visibility / Graphics such that the link you want to see is selected, and in the other Option Set ‘blank’ is selected.
You should now be able to tag these Room elements through to both of the links in the different Option Sets.
EDIT: If the above doesn’t work for you, do this:
In a plan view, move the link you want to tag ‘away’ from the other link a known amount.
Tag the Rooms in the link in the new location, then
Move the link back into the correct place. Revit will prompt to move the Room Tags for you…
Revit does not allow rooms to become smaller than certain dimensions – it simply switches to Not Enclosed when one dimension goes below about 276 mm (when using room separation lines on a rectangular room). However, this dimension may be slightly different depending on the surrounding wall thicknesses.
On the forum, Dimitri Harvalias makes the following observations. When using room separation lines the minimum size seems to be limited to about 1sf. When using walls it appears to have some relationship to the wall thickness used. See the attached image. If walls are 150 wide then the minimum dimension of the room is 150. If some of the walls are 300 and some are 150 then it bottoms out about 85mm. If all the surrounding walls are 300 then I can get it down to virtually nothing.
