In AutoCAD, some hatch patterns are very useful but not available in ZWCAD. We can import and use them in ZWCAD as following.
for example, this hatch pattern named "ESCHER".
Locate to folder "C:\Users\UserName\AppData\Roaming\Autodesk\AutoCAD 2016\R20.1\enu\Support", open "acad.pat" with Notepad. Copy the content of pattern "ESCHER".
Keep ZWCAD closed. Locate to folder "C:\Users\UserName\AppData\Roaming\ZWSOFT\ZWCAD\2015\en-US\Support", open "zwcad.pat" and "ZWCADiso.pat" with Notepad. Paste the content pattern "ESCHER" in the same place.
Continue to open ZWCAD, now the pattern has been added to the list.
