Creating a custom Fill Pattern in Revit

[Anonymous]

I would like to creat a custom fill patter in revit that I intend to apply to the face of an extrusion.  I've converted a .png file to a .pat file, but I keep getting an error message stating... No "Drafting" type patterns found.  Anyone have a suggestions/solutions?

First, your pattern file has to be formatted with the correct header information for revit. See: http://knowledge.autodesk.com/search-result/caas/CloudHelp/cloudhelp/2015/ENU/RevitLT-Customize/file... and http://therevitkid.blogspot.com/2011/03/revit-tutorial-creating-and-modifying.html

Second, I'm not sure what extrusion you are trying to apply it too. Typically you can not apply a pattern to just a face, but instead have to create a material and assign that pattern to the material, then you can use the 'paint' tool to apply the material to a face.

Is this a family or is this in a project? More info please.

Its a Family. I'm creating a fabrication tool for semiconductors and would
like to apply a jpeg to the face of one of the extrusions that make up the
tool. I've created the material already and have converted the .jpeg into
a .pat, but keep getting the error that I mentioned. Additionally, I tried
to just use the image and toggle on the use render image option within the
materials library, but when I do that, the pattern comes in tiled no matter
what settings I try. I appreciate your advise. The thing is, I know I've
gotten this to work in the past, I just can't remember what trick i used to
get it done.

Look at the first part of my reply about adding the header information to the .pat file. You'll have to do it in Notepad. Is that what is missing?

From what you described I would think you need to import the raster image as a decal and apply it to the surface of your choice.

Hi,

Revit PAT files share the same file extension with Photoshop PAT files but are completely different animals.

The Revit message you are seeing is consistent with offering unrecognised content within the nominated PAT file.

Revit patterns are composed of spaced vectors, stored as a simple text file, Photoshop's are raster, stored as binary - or maybe EPS - so a raster to vector conversion would be necessary to derive anything from a jpeg that could be loaded to Revit as a fill pattern. Did your jpeg->pat conversion do that? Try looking at the .PAT file in a Photoshop viewer. Then try looking at it with HatchKit.  The HatchKit Demonstration version will display a Revit fill pattern file but cannot (yet) display Photoshop .PAT raster files.

If the fill is simple enough to suit being represented as a Revit fill pattern then tracing over it with Revit Detail Lines and sending the result to HatchKit from the HatchKit Add-In for Revit will yield a Revit fill pattern.
