I've uploaded a free Revit model showing the ceiling mass technique applied to a project here: github.com/aussieBIMguru/Revit-Files/blob/master/Models/ABG_211011_EmpireState.zip
At first I thought mass in place ceiling family....but I understand what your after now, Good call. Every time, It's always the materials editor within the system family edit mode! I end up creating/naming/applying said material there, but never editing it there.
Great explanations! I'm planning on giving your ceilings method a test run. When I mentioned masses on Twitter, I'm used to using them not for spaces within a building but for multiple building shapes, such as varying length and width of townhouse footprints. I certainly agree that the limited ability for masses' interiors to be malleable makes them an insufficient tool for showing various space options within a single building.
Glad it was helpful! Yes masses are mainly only helpful when you want to use mass floors to automate area takeoff in my experience, but too clunky in other scenarios. I find ceilings handy as they can let users break down spaces into smaller pieces for high level space planning as well.
I prefer ceilings to floors here as they go upwards whilst floors go downwards. For a floor to match a floor to floor i need to offset it by its height but for a ceiling i just set the offset to 0.
Very handy, last week I had to calculate the gross Volume of a house, with a rather complex roof shape. I had to do this by hand (very time consuming) only because the council did a very coarse (and rather unfavourable calculation) to determine building permit rates. Is there an easier way to do this? I could not find a straightforward way of determining the building volume based on it’s envelope. The material browser is always temperamental, somehow it’s a very heavy piece of c++ code that likes to crash a lot. Revit can be so slow and sluggish sometimes as if Autodesk’s programmers have added a few “do nothing” loops on purpose😁.
Thanks, yep those material browsers are lethal. For complex volume calculations I usually model it as a solid form and use Dynamo to regularly read/set the true volume by analyzing its geometry inside Dynamo itself.
Brilliant concept. Any idea how to export these ceiling spaces as IfcSpace-Entities? Adding an IfcExportAs-Parameter to the ceiling category does not seem to do the trick.
Nosiree. Quaddro P5200 - more than enough to run it. It's just a dodgy piece of software sometimes unfortunately - a graphics issue would have told me the window contents cant be drawn.
@@AussieBIMGuru still way more stable than autocad ever was and surprised to see revit crash although many a time it can be non responsive for up to 20 minutes on a large project of many buildings
Yes I wont be going back to CAD anytime soon. I usually find Revit crashes due to the material browser - it is very unstable in my experience and nearly always is what I'm doing in my videos if it ever crashes.

We don´t judge you at all, just as you don´t judge us while teaching with such great love and pain. Thanks a lot.
You're welcome, and thanks for the kind words!

Cheers! Yeah that pesky material editor is responsible for most of my crashes...

Thanks Gavin, great method for feasibility study stage.
Cheers Adam!
Thanks man, very useful.
I'm just wondering why you are using ceiling instead of floors ??

@@AussieBIMGuru I thought so :)

Yes if I recall some of the system categories have hard programmed limits unfortunately. I'd suggest post processing using something like BlenderBIM.
Similar can be achieved with floors as well, great trick nonetheless!
Indeed, but you would need to offset the floors given they go downwards from their drawn level.
failed because of bad graphics drivers no doubt !!
