SAVING AUTOCAD DWG AS .PAT FILE

[Anonymous]

I made this very custom wood grain hatch pattern that I eventually want to import into revit as a custom fill pattern. But first, I must save the .dwg as a .pat file and I cannot figure it out. Please help.

Hatch file has extension .pat

A .dwg file can't convert to .pat

It's not as simple as you think, you have to write definition for the pattern.

That can't be a Hatch pattern.  They consist only of straight-line pieces, defined in linesets at specified angles with pen-down and pen-up sequences, and things need to line up along the same angle in the repeats.  Something like that could probably be approximated in a Hatch pattern, but I suspect it would be an enormous file, as Hatch pattern definition files go.

You could put that into a Block and use SUPERHATCH.  But first, I'd "fix" the ends of those Splines -- things don't meet up well on repeat:

That is a very finely detailed pattern and its fidelity may reward where deemed necessary.   

It is not difficult to create the pattern from a DXF exported from your DWG with some cleanup at the borders as provided in the attached file but in most circumstances a lighter, simpler pattern would avoid the size and speed impacts of employing a pattern containing over 2000 elements.  

Revit already has some far simpler woodgrain patterns in the standard file revit.pat that with 92 elements may be too crude for your purposes but I feel there could be room for a compromise to be found somewhere between that and the 2065 as contained in the upload.  Finely defined arcs and splines come at the price of requiring many straightline segments to closely approximate them. 

Revit will not load the attached pattern without the assistance of the HatchKit Fill Manager for Revit but does work once loaded via that add-in.  The pattern should also load to AutoCAD.

thank you all

Why don’t you just import the dwg wit the custom hatch pattern into Revit? Then the pat will automatically get generated in Revit
