Choose One / Get One progeCAD Add-on Free from CADDIT

Until 31 December 2009, new buyers any CADDIT CP-System progePLAN module will get the second one for free, provided that the user also purchases the yearly maintenance plan for both modules (@AUD$140.00 each). This offer will only be available by direct request to CADDIT, please contact us for more details. All new users will also receive a free upgrade to soon-to-be released CAD-Profi 7.

progePLAN/CAD-Profi System is a comprehensive collection of four individually licensed, specialized 2D design modules for:

• Electrical and industrial circuit wiring, lighting, fire & safety, power distribution or telecommunications plans and schematics
• HVAC and plumbing, water-supply-and-sewage, medical, cooling duct installation and gas distribution design
• Mechanical design, parametric steel profiles, comprehensive mechanical parts library, steel pipes, industrial equipment of heat exchangers
• Architecture Design for building planners to easily draw basic architectural design using walls, parametric windows, doors and more.

CAD-Profi System is a CAD software add-on which works in AutoCAD, AutoCAD LT (using LTX extender available form CADDIT), progeCAD, IntelliCAD, BricsCAD and many other systems. Users can download a free 30 day trial of CAD-Profi System HERE.

Who is the Best BIMmer?

For those not familiar with the expression, BIM stands for Building Information Modeling. BIM is common tech speak for using information-based building semantics in CAD design workflows. The exact definition is actually still evolving. BIM products include the likes of Autodesk Revit, Graphisoft and Bentley. Two things generally characterize BIM software: increased program complexity and higher software costs. Some liken BIM in the architectural industry to PLM for product manufacturing.

We would argue one important difference: PLM was a customer driven concept to meet large scale manufacturing needs. However, "few have pursued full 3D (building design) modeling with great vigor, and even fewer have embraced BIM and information extraction, even though the AEC software industry has spent much time and capital creating and promoting BIM software," states Goldberg, H. Edward in CADalyst magazine. So a large portion of the need for BIM software may be originating from the software companies themselves.

One thing almost everyone agrees on is that there is a right way to BIM and a wrong way to BIM. But that's about where agreement ends. How to BIM depends largely on which marketing team one chooses to listen to. Autodesk, Bentley, Nemetschek and others are all staking claims "to BIM the Best" in what appears to be the CAD industry's latest gold rush to establish a title standard.

The question arises if this will actually be a standard that most businesses need. Full scale BIM deployments can be very expensive. They may requiring extensive retraining and, in some scenarios, a complete refit for design and business workflows. Interestingly, none of Autodesk's ROI charts seem to take this last aspect into account. And even if large companies succeed in (at least partially) implementing BIM, will the solution scale downward for small business and supplier integrations?

Previously on our CAD Blog we introduced our low-cost BIM alternative CP-System, which can be dubbed our "Anti-BIM" proposal. CP-System offers AutoCAD, AutoCAD LT (using LTX), progeCAD, BricsCAD, ZwCAD, CADopia and other IntelliCAD brands quick but accurate HVAC, electrical, plumbing, architectural, mechanical, structural, hydraulic design with extensive parametric symbol libraries. More information about CP-System and a free 30-day trial is available HERE.

Free Online CAD Symbols, Models and AutoCAD Blocks

There are many places available for downloading free CAD symbols and AutoCAD DWG DXF blocks from the Internet. Ready-made CAD symbols can be inserted into CAD drawings instead of creating them from scratch, therefore saving a designer time and making their job easier.

CBEN (http://www.cben.net/) home to one of the largest communities for continually updating large free AutoCAD DWG block libraries of anything from construction and architecture to vegetation, people, 3D models and more. All downloads are free. If you work a lot in AutoCAD and don't know about this site, you probably should.

Polantis has just launched a new but extensive visual website for 3D designs of mostly IKEA furniture - lots of IKEA furniture. This library already offers a good selection of their build-it-yourself virtual furnishings.


Archibase offers many free CAD models and patters, but this website seems to want users first to install a free "Archibase Toolbar" on their browser before downloading any blocks. We didn't care to, but I guess you can if you want...

Designers might also try http://cad.3dmodelfree.com. This site offers a visual library of drawings containing numerous blocks and templates for interior design, room and building drawings, furniture, shopping centers, elevation plans - even some Chinese symbols. The drawings come mostly RAR compressed, and some use passwords but the password is normally displayed on the web page for downloading that drawing as far as I can see...

Engineers looking for free 3D mechanical parts can try Dassault's http://www.3dcontentcentral.com. At first glance this site appears to go beyond offering simple CAD model downloads by trying to tie users and vendors (the model contributors) together with what appears to be an almost WEB 2.0 approach. I remember our first try with one of the listed suppliers (for a 3D stepper motor model I think) kept returning an error that the model wasn't found or couldn't be downloaded. But usually it works rather well I guess - offering all kinds of free 3D mechanical industrial vendor models in various formats like STEP IGES ACIS .SAT (for AutoCAD) and much more...

http://www.woodworkersworkshop.com/cadfiles/index.html offers a small list of free CAD libraries and links to more libraries for wood working.

Of course, there are also many downloadable CAD symbols libraries as well. progeCAD Professional design CAD includes a free library manager with about 11,000 AutoCAD blocks called ALE. CP-System takes 2D CAD blocks a step further, giving users the ability to add, insert and modify new CAD blocks parametrically.

If you have a good link to free online CAD block or model resources you would like to see added to the list, feel free to post it in the comment section below.
