reconstruction of an old Lift-bridge

can no-one help? ;(

this may go in an application specific forum, but since its here anyways... what's your problem? It looks incredable easy to model (I mean you have professional blue prints of like every aspect) and its mostly blocky shaped, no organic smooth parts you have to worry about...

I would first model the frame... (start with a poly cube, extrude, etc...) and then just get the shape, then add the cables or support beams, or whatever, and add screws, and and wires.... I dont know how many different techniques you can use on this kind of thing :D

Anywho...
Cheers,

If I had to do this myself and I still had access to the prints (which is sometimes an issue)...

I would start with the simplest shapes that define the volume of the structures, then transmap the prints onto that. I would use that as a guide for laying in the structural members. Then lots and lots of instances.

I think, for me, that would be easiest.

Hey, isn't that the old bridge in Rotterdam :)

Hmmm, i will post in dutch from this point on, sorry to any other viewers.

Ik zou als eerst beginnen met het maken van een profiel van de balken die gebruikt worden. Meestal hebben de balken een simpel H profiel. Hoewel ik niet weet of dat bij de Willemsbrug ook zo is/was. ( volgens mij staat er nog een stuk )

Het is simpel om de balken in lengte aan te passen als je een extrude doet van het profiel, omdat er nog al wat verschillende lengtes in zitten, maar de balkbreedtes zijn denk ik door de hele brug wel gelijk. Dus je zou al snel de dwarsbalken over de afbeelding uit kunnen leggen. Je zou eigenlijk ook wat onderzoek moeten doen hoe de balken aan elkaar vast gemaakt zijn, met nagels of lassen.

Verder zijn de 3 delen waar de brug niet opkomt denk ik identiek, dus dat scheelt weer wat werk.

Since I have Rhino2.2 I would start up a template with a scaling that would best fit the bridge. Like every 5 squares is a foot or maybe a meter. Anyways then I would draw out the frame, in curves. I would then use the tool Sweep 1 Rail to make out the beams of the bridge (the curves I just drew) with another curve, called the cross-section. It is a very simple tool. You have a curve that looks like the foot print of a beam (like if you stood it up) and a curve that is the length of the beam in the position you want it. Put the cross-section at the end of that curve and bam, you got yourself a rail. Then I would move onto the road surface, whatever it maybe, and then the supports underneath the bridge. And then I would tackle the cabling. Because you could do the cabling all detailed, or with the simple piping tool rhino has. It depends on how much time you have.

but this is with Rhino, I don't know what software you have and if that software has the same tools.
