This is a rough list of thoughts we still need to discuss, before moving them to the front page:
  
=== CAD Data formats ===

=== opendwg replacement / data format ===
 
Why do we call it an open dwg replacement?
 
 
 
My view is that there is a need for a free 3d CAD Software and a free 3D Data format. These two go together.
 
Ideally the cad package should not just resemble what existing proprietary packages do, but also contain features like novel ways of community & collaborative design work.
 
 
 
=== 3D CAD Software around ===
 
* www.opencascade.org - the opencascade project provides a software stack that has many foundations for CAD/FEM/CFD Software. It was started or at least is pushed by airbus - i think to avoid vendor lock-in with long running aeroplane design projects that go on for decades. Derived from this is "salome"
 
 
 
* sourceforge.net/projects/avocado-cad - avoCADo was recently startet in java. It is in very early stages, aimes for cross plattform use, but i fear java the wrong choice for a demanding piece of software
 
 
 
* blender.org - once had the idea to fork a cad version. However CAD is mainly about 3D geometrie driven design and then deriving 2D drawing from it. Blender is about artists expressing there imagination. But - the 3D displaying technology and rendering is there, blenders interface is very theme driven, maybe a starting point.

3D Printers, Rapid manufacturing & tooling, and various other technologies to "grow" parts are available and will spread in the foreseeable future. Free design communities are there, much like free software communities, but lack software to design and share parts, models, etc.

Revision as of 14:03, 10 February 2009

This is a rough list of thoughts we still need to discuss, before moving them to the front page:


Mailing lists


We need to have a mailing list for "Free" CAD system so that we can invite more people and have faster interactions.

  • ask on the cad-linux mailing list, if we can discuss matter there?
  • once we now where & what to head for, there should be a project with related mail list

Getting up to speed

At the moment this "Priority" project is not gathering momentum as interested people are more of users than developers. This is a general problem, since cad software is not used by developers. Free Software so far is often started, because software folks scratch there own itch. How can we motivate developers to contribute to this kind of software? In return mechanical, architecture and design engineers can start free design projects and build something software folks may like :-)

I do see many developers working on various GPL licensed CAD software we need to bring them on one platform to drive this project. Lets create an invitation mail which can be sent to these groups of developers/users so that they can visit FSF priority project

About open CAD formats...

page this group has already started generating an open CAD format it seems.

I also thought that collecting the information on KNOWN CAD FILE FORMATS will also help us understand how vivid these formats are hence created one section in the main wiki.


DRAFT INVITATION to existing projects

Here is draft of the invitation which we may send out to people known to have interest or are already developing a CAD solution under GPL.

We understand that you are (actively involved/interested) in CAD format freedom.

Free Software Foundation is popularly known as FSF and a foundation spearheading the Free Software Movement under the GNU GLP license. They identified the need of a Free CAD Format as a High priority project.

Please check out FSF High Priority Project list at http://www.fsf.org/campaigns/priority.html for more information.

FSF also created a wiki for project coordination at http://groups.fsf.org/index.php/OpenDWG_Replacement The goal is to have a free CAD format and to concentrate activities in order to develop a free, portable, 3D CAD software.

We have checked and found that there are various groups working on Free & Open CAD formats and software.

In an effort to converge all efforts to the creation of a widely accepted standard for CAD and a software along with it, we invite you to register and participate in this "FSF High Priority Project".

Any support would be of greatly appreciated.

UnQuote

Taking it as "High Priority" we must finalize this draft by 14th Feb and start sending them.
