OttoPDF

A freeware program that converts AutoCAD drawing files into Adobe Acrobat PDF files without using AutoCAD. It supports sheets upto E size, variable pen widths and it can “print” the file at varying resolutions in colour or grayscale. The new version of OttoPDF supports compression of PDF files when used in batch mode. The only drawback to this program is that OttoPDF can’t deal with TrueType fonts although it will work perfectly with AutoCAD’s native SHX fonts.

CadDepot

CadDepot also has a massive collection of blocks to insert into your drawings. Not all of them are freeware though and please look out for blocks that have been created by unlicensed versions of AutoCad. If you’ve ever had your drawings “infected” with the Educational Version watermark, you’ll know why this is important to check.

There are also lots of Fonts, font utilities and LISP routines so subscribing (free) to their newsletter will inform you of updates. You will need to sign up to access the files at this site anyway and it is well worth it in my opinion. They have never spammed me till date.

They also have a “make font” utility designed to aid in creating and customising SHX fonts. The program is designed so that anyone can customise fonts without having a thorough knowledge of shape files.
