Revit Hatch Patterns

September 24, 2011

This seems to be a hot topic as the majority of the hits on this blog regularly access the one post we have on hatch patterns that Kirk posted in 2010.

“Revit Masters,

Below is a nice hatch creation tool for Revit that I was able to use to accurately draw an abnormal brick pattern.

Download the 3 files and place in your C:/ProgramData/Autodesk/Revit/Addins folder and it’ll show up in your Addins ribbon.
Follow the instructions below and its pretty self explanatory.

Much Thanks to Tim Kauffman (Architect at GLHN) for providing the link to this handy tool.

Here’s a methodolgy descriptive I posted back in 2008 on AUGI that involves creating a ceiling demolition pattern.

The text file that needs to be edited to receive the code below is found at:
C:\Program Files\Autodesk\Revit Architecture 2011\Data

It has a “PAT” icon and is titled “revit” and is a “DWG TrueView Hatch Pattern Definition” file type.

In explorer go to the file but don’t’ open it. You need to change it’s properties to turn off the ‘read only’ protection by right clicking on the ‘revit’ file, go to properties, and uncheck ‘ read only’

Then open the file and paste the following code into it. I revised the initial name to get it to order itself next to the ceiling patterns and added the 24 x 48 Tiles text to match the other entries. Not sure if it was necessary but I wanted to cover all the bases just to be sure. So the text reads as follows:

*Ceiling-Demo 24×48, 24 x 48 Tiles
0, 0, 0, 0, 24, 2, -2
90, 0, 0, 0, 24, 2, -2

Save out this file once you are done.  I save my patterns to a Master Library File under a folder structure called Support>Patterns this creates a location where all updates are located and prevents the updates from being associated with a particular Revit install, which may get removed or you may make updates to later Revit version pat files and wind up having your patterns spread across various version installs.

Now open Revit. You will need to create a new material “Ceiling Demo 24 x 48” and then edit its surface pattern.

1.  Select the model component in the RCP, in this case it would be a ceiling.

2.  Then in the properties dialog select “Edit Type” then for the row entitled “Finish”

3.  Under the material column select that cell and you’ll see a drop down button appear to the right.

4.  Select it to open the materials dialog.

5.  Then go to the material entitled “Finishes-Interior-Acoustic Ceiling 24×48”

6.  Select duplicate in the lower left corner and amend the offered title to add “Demolished” (note 48 changes to 49)

7.  At the Surface Pattern  to the right select the drop down button to the right.

8.  The “Fill Patterns” interface should then appear.

9.  Select “new” then ‘custom’ then ‘import’ then import the file at this path
C:\Program Files\Autodesk\Revit Architecture 2011\Data
(Note this will change if you relocated the file to a master library or as you receive Revit upgrades Revit will want to point to the PAT file of the latest version you are using.)

You will then have a number of patterns to select from, one of which will contain the new demolished ceiling pattern.

Select it and you are done.

There is a descriptive at the beginning of the PAT file which tells you how each of your numerical inputs in the pattern code influence the pattern.

If you are into coding you’ll feel right at home here.  Not a place I like to go though.
