Hello, i saw this in FME documentation :
“...
The ACAD format writer will look for custom hatch patterns in custom <filename>.pat files located in folder specified by the ACAD operating system environment variable, or in the related folder for any installed AutoCAD product.
The REALDWG format writer will look for custom hatch patterns in custom <filename>.pat files in the <FME install folder>/plugins/realdwg/Support folder. Predefined patterns can be found in the acdb.pat file in that folder, and additional patterns can also be added to that file.”
The Autodesk AutoCAD DWG/DXF Writer is fine : i get custom hatch patterns in my dwg file. (didn’t try REALDWG Writer)
But when i use the Autodesk AutoCAD Map 3D Object Data Writer, i get the warning :
“AutoCAD Writer: The combination of pattern type 'Custom-defined' and pattern name 'MYHATCH' was found to be invalid. Using a default predefined hatch pattern of value of 'SOLID'”
How are custom hatch patterns managed in this case ? (using FME Workbench 2025.0)
Thank you.
