Floor Split Face Tool

[cjcarch]

I'm working my way through "Revit 2012 - No Experience Required" and am doing the tutorials for creating the office building.

The author has the reader split the ground floor surface (which is carpet over concrete slab) at the restrooms to show a tile surface. I've done that and it seems to be OK. The carpeted areas show as they should and the tiled area shows the tile lines, as they should.

If I go to the split face area to edit the boundaries, Revit goes into the sketch mode allowing me to modify the boundary lines as needed, however the whole floor area (tiled area and carpeted area) automatically begin to show the tiled surface at both areas. I finish modifying the boundary, expecting the tiled area to show only in the restroom, however the entire ground floor, which is supposed to be carpet on slab now has the tile grid lines. When I go to the Assembly editor, the settings are correct for carpet on slab, but the tile lines still appear.
Any idea on what is causing this?
Thanks,
Carl

I'm going to go out on a limb here and say, that's not the right way to do it.

Model the slab as a slab and the floor covering as a floor covering over the floor.

My guess is that this is another "flaw" in the system. There's a lot of things if revit, that if you modify one part of it and they try to split if from the whole or modify the original, revit fails.

The whole slab on grade is done by one guy, usually. The floor coverings may be done by many different trades, and most likely more than one mfr. The specs for the slab on grade usually reference additional criteria for each floor covering. Hence, while it's all a 6" slab on grade, made from the same mix, the area that gets carpet can get carpet much earlier in the construction sequence than say vinyl, which needs more time for the concrete to cure and the moisture to come out.

Also the slab on grade should be a part of the structural model, while the covering should be done by the Archies. ie make 2 floors. One for the slab and one for the cover. Just my Humble Opinion.

I had a similar problem just the other day. It is a glitch in the matrix. Like Dave said, model it like it's built in the real world: conc. slab floor with a separate tile floor on top.

Thanks for your replies.
I went back to the exercise today and redid it and it worked fine, just as the books instructions. Knowing the hassles I had last night, I undid it and tried it again. It did it incorrectly, just as it did last night.

I then went back to the book and discovered on the next page some text that I totally had missed.
Obviously, I'm not the first one this has happened to. The text from the author said:
"Wow! My Materials Flipped! There is a glitch in this function that , although annoying at times, can be easily fixed. If your materials did in fact flip, you need to remove the paint that Revit accidentally added to your floor. Click the Remove Paint button (pull down from the Paint and the floor will start behaving for you."

I did it as he suggested and it worked fine.
Once again, thanks for your suggestions.
