[dxf] reading entities not used (can be purged) Printed From: CAD Forum Category: EN Forum Name: AutoCAD Forum Description: Discussion about AutoCAD and AutoCAD LT, viewers, DWG and DWF formats, Design Review, AutoCAD 360, add-ons URL: https://www.cadforum.cz/forum_en/forum_posts.asp?TID=2626 Printed Date: 01.Jun.2026 at 02:13 Topic: [dxf] reading entities not used (can be purged) Posted By: massimo_74 Subject: [dxf] reading entities not used (can be purged) Date Posted: 04.Nov.2009 at 15:18 Hi, I've a little problem reading DXF file with my own application. In my program I see entities that in Autocad there is'nt, can be PURGED. Reading che DXF file, how I can understand when a block (or entity) is not used (can be purged) and the i can leave invisible? What is the attribute of an entity that can be purged, hw I can see in the DXF code? Thanks, Best Regards, Massimo.

Or...before making a dxf from AutoCAD, purge it first :)
