ok... glad this got some interest... here are the facts.
Its a "look and feel" thing, so creating to connectors is "easy" this would get the basic ends.
What i need to achieve is something I can look at in 6 months and know "6pin male end to 6pin female end", then "5 wires all black expect 1 with tubing then heat shrink". This is definitely not being used for PCB board creation (we have software for that already).
So the idea is very basic, it would be tubes in groups with colours, I tend to be quiet accurate so I know that certain wires are 1.1mm in diameter which would be a pipe this wide then sleeving 4mm wide to contain that wire etc....
The idea was we used to (well started) doing it in Corel Draw, however that really isn’t good when doing this stuff as you really need it 3D so you can move around it, esp when you have arms coming off, its quiet hard to "see" 20mm is heat shrink on Corel Draw, however you could explode this in SU (with a plug-in) and see there’s 20mm of heat shrink and it can be labelled as well.
So this is no more than a documented wiring construction method drawing, however it doesn’t need to be actual "schematics" we use other software for that type of thing, however the end connectors would be labelled such as "6pin male A, A.1 > B.2 etc..." this shows which pin is connected to which other connector (as another would be labelled "6pin female B etc..."
However sounds like there isn’t a plug-in of such, I have seen the "pipes" plug in, think i would prefer to do me own pipes, would be easier i think (all cables would be 90 degree bends for ease of construction.
Of course, unless anyone else knows of a real electric diagram / connector / construction software I would be interested, however not come across one yet (that didn’t cost more than about 5k anyway).
I might knock something up so you can see it, however that means I’ve done the job then
