Hatch pattern scaling - How to scale hatches?
HatchKit provides a convenient scaling control:
Alternatively you can multiply all linear measurement items in a hatch pattern definition file by a scaling factor. In AutoCAD and similar pattern file formats the first item is an angle so should not be scaled. Other file formats differ - for instance DataCAD 12 precedes the angle with other unchanging information.
Excel can open the hatch pattern file (alternately Get External Data from the Data menu). Select comma as delimiter. Create a new worksheet with scaled linear measurements (B onwards for AutoCAD, D onwards for DataCAD). Save that worksheet as a .CSV file and ensure that all lines comply with the maximum allowable line length. Rename the file to suit your CAD system.
Rescaling hatch patterns for Revit requires extra care to ensure all pattern elements have repetition lengths within the limits for that pattern type.
