Drafting patterns change with scale, whereas model patterns keep proportions when changing scales. Revit includes two PAT file types: model pattern files and drafting pattern files. AutoCAD and Revit have different compatibility issues since Revit hatch patterns can work in AutoCAD but AutoCAD hatch patterns may struggle to work in Revit. PAT files instruct AutoCAD and Revit how to draw the lines that make up the patterns, also referred to as hatch patterns.
The Use of PAT Files in AutoCAD and Revit We sat down with Tyler Webster, Senior BIM Developer at CADdetails, to talk about PAT files, learn what they are, and what type of building and landscape product manufacturers can benefit from providing these to the design community. These files are used by CAD software and contain hatch patterns that provide information about pattern or texture. Pattern Files, or PAT files, are CAD files with a. When manufacturers are considering having content developed for the design community, some manufacturers may be well served by having pattern files created for their products.
