Revit interior finishes for tiles with free apps

I don’t usually do ceramic tile finishes, but I’ve just had the opportunity of doing some on a recent project.

There are floor tiles and wall tiles and feature tiles for an accessible toilet that I will use as an example.

This is near the finished set-out for them, a few more dims and schedules for fixtures etc and it’ll be ready to go.

Floor Plan with tile set-out, Reflected Ceiling Plan (RCP) above, 4 internal elevations and a couple of 3D views and a legend for the tile types.

The two add ins that I used to set this up were:

Room Finishing (free Add-In)

Room Finishing by Bim 42, which I think is a brilliant tool  for putting a 3mm thick floor on top of the base floor and also 3mm thk walls on the 4 walls by selecting the room, it then creates the internal walls, a second run creates the internal floor. Also great for scotias and skirtings too.

See video below:

BIG WARNING. If you dont select “Only selected Rooms”  it tries to grab all the rooms and can freeze your instance of Revit. Unfortunately it defaults to ALL ROOMS IN CURRENT VIEW so be careful. I have had to reboot Revit and have lost work because of this.

Now there are a couple of subtleties to this add-in.

1.You may need to use the JOIN command with the main wall and the finish wall to be able to show DOORS, WINDOWS & other openings.

2. There is a massive advantage in that you can get the NET ROOM WALL AREA ( less openings such as Doors and Windows) using this tool.

pyRevit (free Add-In) Make pattern

The second add-in tool I used was the pyRevit Make Pattern tool by eirannejad . I’ve only recently come across this tool and I’m very impressed by the bits I’ve used so far. I used this tool to create custom patterns (model & detail) to apply to the walls as I wanted a stretcher bond (staggered) rather than a stacked bond as this reflected tiles that were already existing in the building. It is hard to do this with Revit OOTB (out of the box). This tool is brilliant for custom patterns. See the video below and search on you tube for pyRevit pattern.

I wanted the wall tiles to be staggered and there was also a line of feature turquoise tiles. These I could use a region on in the Elevations, but the region tool does not work, in R2018 in 3d view, even when locked, so I couldn’t use that there and the paint tool just did the whole wall, so I’d have had to break the walls into 3 separate pieces to be able to show the feature turquoise band, which all seemed a bit much.

As I don’t do many projects with tiles when I went to the tile showroom and chatted with the salesperson they mentioned the grout lines between which was often neglected by builders, causing a cut tile as the setting out had not factored in the grout line. So when I made the tile pattern I allowed 1.5mm between tiles for the grout.

Close up of the tile pattern I created, with a Region over the top for the feature turquoise tile. Note on left side the thin 3mm wall which is what the tile pattern (material) in on

That was interesting. As when I started setting out the tiles vertically in a 2400mm high room  I needed to allow for another 50mm (2″) to get a full tile at the top. This pushed the ceiling up.

This is the nice thing about doing a floor on a floor, you can start the walls from the tile floor so that your set-out accommodates the floor tile thickness (+ bedding compound) so that you set your Ceiling height realistically to accommodate all these extra tolerances.

When I first used the Patter Maker instead of making the pattern two tiles high, I made it the full 2400mm high. When I revisited the pattern to allow for grout joints I only had it 2 tiles high.

I think there is a way to show the feature banding in 3D views by creating a pattern 2450 (allowing for grout) and use coloured lines for the feature tile, that way it will display in the 3D views too. A test for another day.

End Comment

These free tools allow you to:

Make stylised pattern finishes to your walls in any pattern that you choose to create. I don’t think you can use filled regions in the patterns but have only used the tool briefly so cannot confirm this.

You can extract NET wall areas and floor areas using this tool so can schedule tile areas. A thought I’ve had on this is that if you have detailed with grout in the pattern you may be over-estimating the tile area in your scheduled take -off. ( You would schedule the thin walls (3mm tile)  to get quantity takeoff for tile area).
