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.

I'm not sure where this standard definition is at these days, or whether it could be used to automate what I'm doing by a clever MetaWiki robot coder, but I (and others) started capturing some connection information in BrickWiki ( (URL) ) You can (...)
