Great HVACR Software Links

Katmar Software (Free Software) Various engineering software applications.

Paul Milligan (Free Software) Paul originally setup the two newsgroups alt.hvac and sci.engr.heat-vent-ac. Paul and Andy Shoen co-authored PMTherm.

Andy Schoen (Free Software) Andy, as I understand, does much of Sporlan Valve Companies R&D. He would have written much of the software and literature available on the distributed Sporlan CD. Andy has developed a neat little refrigerants properties application too.

Randy Wilkinson (Free Software) Randy has written some really handy hvac software much of which he gives away for free.

dwg2zip.zip - Dwg2zip is used by architects and engineers all over the world to make AutoCAD drawings ready to share with project participants. The new version 2005 brings new features and improvements to this popular program.

What can Dwg2zip be used for ?
Dwg2zip can bind xrefs and remove frozen and off layers on a group of AutoCAD drawings. Dwg2zip can also convert to previous AutoCAD versions and dxf. Drawing files, drawing lists, fonts, and plotter configuration files can be compressed into a zip file that can be sent by email. The program can also unzip zip files. If a zip file contain drawings, fonts or plotter configuration files then Dwg2zip unzips to the right path on your PC.

Dwg2zip makes sharing drawings easy
Xrefs are a very useful feature with AutoCAD. But to distribute drawings that contain Xrefs is a challenge for many AutoCAD users. Xrefed  drawings must then either be bound to the main drawings, or distributed as separate files. Dwg2zip changes this by automatically binding Xrefs to the main drawings. And the drawings can be cleaned and purged for unwanted layers before distribution. This can be done without any changes made to the original working drawings.

I hope that reading the above information was both enjoyable and educational for you. Your learning process should be ongoing–the more you understand about any subject, the more you will be able to share with others.
