Another question is about changing a fill pattern’s dimensions e.g. to make a face brick wall surface pattern match the South African face brick course height. Currently the problem is that the current Brickwork surface pattern course height is 75mm. See below. We want to change the Brick 75×225 pattern to an 85×225 pattern.

How we’ll accomplish this is to edit the .pat file that these fill patterns reference. Open the Fill Pattern dialogue box by going Manage->Additional Settings->Fill Patterns. Make sure you’ve selected the ‘Model’ Pattern type at the bottom of the dialogue box. Then click New->Custom->Import. See below.

Browse to the install directory of Revit which is typically: C:\Program Files\Autodesk\Revit 2015\Data. In this folder you will see then select the .pat files. What I now do is to copy and paste the ‘revit metric.pat’ file into the same directory so as to create a copy of this original file.

Right click on the copied file and Edit or Open the file. The .pat text file will open in Notepad by default. Note the text related to the Brick 75×225 wall pattern.
