The patterns in both files are the same except for the dimensions used. acad.pat contains the hatch patterns used in imperial drawings, and acadiso.pat contains the hatch patterns used in metric drawings. The standard AutoCAD hatch files are acad.pat and acadiso.pat (aclt.pat and acltiso.pat for LT). You need to locate your existing two standard AutoCAD (or LT) hatch files, open them in a text editor, then copy the hatch pattern code from my file (hatch_pattern_code.txt) into them. You will then see the new hatch patterns alongside the standard AutoCAD patterns in the "Other Predefined" tab when using the BHATCH command. Make sure there is a carriage return at the end of the last line. I hope this helps and have a great weekend.For AutoCAD 2009, 2008, 2007, 2006, 2005, 2004 LT 2009, 2008, 2007, 2006, 2005, 2004Ĭopy and paste the entire contents of my file hatch_pattern_code.txt into your acad.pat hatch file and your acadiso.pat hatch file (aclt.pat and acltiso.pat hatch files for LT). select a scale suitable for your purposes.
click on the pattern to pop up the local editor.load the pattern to Revit as a DRAFTING pattern.install the free HatchKit Add-In for Revit (From our website here or from the Revit Exchange).To create a MODEL version for this pattern of whatever scale you like:
HatchKit's AutoArrange function reduced that to 45 line definitions with identical appearance to the original and file size of 4.5Kb rather than 116Kb.īoth the original and the revised pattern versions readily load to Revit 2016 as INCH DRAFTING patterns however the scale should be increased by about 50X to load as an INCH MODEL pattern - the pattern is far too small to load 1:1 and suffers from Revit's imposition of a minimum stroke length if loaded with a scaling between 5X and about 20X. There are quite a few patterns out there which contain redundancies as discussed here: and this is just another example. The pattern that you sent me contained 1385 line definitions.
