Securing/Encrypting Hatch Patterns Printed From: CAD Forum Category: EN Forum Name: AutoCAD Forum Description: Discussion about AutoCAD and AutoCAD LT, viewers, DWG and DXF formats, Design Review, AutoCAD web, Drive, add-ons URL: https://www.cadforum.cz/forum_en/forum_posts.asp?TID=4736 Printed Date: 12.Jun.2026 at 22:31 Topic: Securing/Encrypting Hatch Patterns Posted By: Kamyar Subject: Securing/Encrypting Hatch Patterns Date Posted: 08.Nov.2010 at 17:50 Hi folks. I'm a programmer, new to this forum, and have not had much experience using AutoCAD. One of my friends has written some hatches for AutoCAD and is interested in selling them.He asked me if that's possible to deploy the hatches without letting the end user access the source (at least not in plain text). As far as I could find out, AutoCAD saves the hatches in a .ptn file in plain text. Is there anyway that I can alter the way AutoCAD accesses custom user hatches and at least make it not very accessible for his customers? Thanks in advance.
