You can see what we've created so far here:

http://brickwiki.zapto.org/index.php/Category:Connnection_Types and the
articles
in that category...

Do people think this is valuable? Would people like to take a crack at adding
more types? Or rendering the needed images for the types there already? or
refining the ConnectionTypeBox?

Wikis are editable by anyone... if enough people capture what they know on
BrickWiki, this one will be really cool.


While a connection database could be helpful, I just cant help
thinking that a relationship/constrain system like solidworks and
Pro/Engineer use could acheive a lot more.

It could certainly be a start, then simplified - so the CAD
applications (MLCad etc), then try (with confirmation) to make
assumptions that you want to place a peice on that one - with the
studs attached as so. It would be nice to tell it to center an axle in
a hole and so on.

This could get interesting though - as there are no real curves and no
parametric definitions, and therefore no center points defined - so
creating a "concentric" or "tangent" constraint could be difficult.
This may be contraversial (very) but an extension to the LDraw
standard could allow more advanced clients to work with parametric
definitions, and then render them into simple meshes for use in
others.

Just my two pence worth, I used to be a software engineer with a large
CAD corp - so I have a lot of ideas on this stuff.

Note that Rosco already did take a crack at a few, including generating some images for them, and in doing so, found a problem in one I created, and caused me to decide to add fields to the connectionTypeBox, which is goodness.
