These are used in the below diagram.Īlso, each line of the definition is shown in a different color for clarity. Col 7 - Space: Length of the invisible part of your line if you want a solid line, make this negative of your Col 6 Dash valueĪlright, so all the columns up there have a letter (A, B, C, D, E, F).Col 6 - Dash: Length of the solid part of your line.Your office may have a set of established patterns. Col 5 - Offset: Distance between each time the line you are defining repeats This is often necessary because of Revit's current limitation in creating natively complex patterns.Col 4 - Shift: Shift of pattern over from line to line I generally don't use as it's a little past my needs / skill level.Col 3 - Y: Y coordinate of the origin of the line.Col 2 - X: X coordinate of the origin of the line.Col 1 - Angle: 0 = parallel to X axis (horizontal line), 90 = perpendicular to X axis (vertical line).It's easier, to me at least to think of it as a spreadsheet (sorry guys, limited formatting with the tables in this editor, see attached EXCEL): Angle Go to the Manage Tab>Additional Settings>Fill Patterns. So a PAT definition looks something like this: This simple text file should be renamed as a ‘.PAT’ file before importing into Revit. The goal of this article is to explain what the various numbers in the PAT definition mean. Before modifying PAT files, always make a copy of the original PAT file you intend to use as a base you don't want to risk messing up other files that. To learn about the basics of how to make a PAT file and import it into Revit go here: To me the easiest thing to do was to make an excel spreadsheet and then a diagram showing what all the columns meant. Now that I've figured it out, I'm putting it out there. What do all the random numbers mean mean? Why do some rows have more than others? What properties of the lines do they affect? Why do my results always seem so random? I spent hours scouring the internet for a clear explanation of the PAT file format to make a custom hatch for REVIT. there is a file called revit.pat (But i notes that revit did not use it ) Report.
