Tensile structures
-
How do you model a true tensile structure like this. I would like to be able to dimension it as well. I tried a curved mesh in plan. But each anchor has a dif elevation. The edges curve in 3d. This is the part i'm trying to control is the 3d curve. Any help is appreciate.

Hello LAPX
Try the Soap Skin & Bubble Plug-in.

Also try bez-patch http://groups.google.com/group/Ruby-API/browse_thread/thread/1dae3f4aeb4eee53/54db2fbd7818caa0?lnk=gst#54db2fbd7818caa0. It may be easier to tweak the outer edge. An easier to load zip file is toward the bottom of the thread.

I have both scripts and though I love bezier patch, for these structures I think SSB is the best.

Lapx,
I would try using the following (fantastic) scripts:BezierSpline.rb - To draw the curved edges of the structure / edit edges
Weld.rb - To join the edges (optional )

I agree with the above comments, but you could most probably also use the lofting script (skin.rb I think) once you've drawn the perimeter using the bezier script (or whatever you choose) and make a section in the middle. Somebody here did a tut on making a dress which got me thinking.

this is definetly a soap skin job. all you have to do is draw in the outline of the shape you want and it will do the rest. although im sure it can be done with the bezier tool, i think it would be a lot easier with soapskin, maybe thats just me though!

I would recommend using an application designed for a job like this eg. Rhino.
There is a free trial that allows you to save 20 times. Enough to get a few jobs done.
If you use the rhino .skp exporter from Rino labs it will export the mesh beautifully.
Hope that helps. -
did a quick tut to help you get the general idea. It's my first one so don't be too cruel!
oh and you'll need the soap skin ruby for it.

The bezier curve did the trick. I am already familar with soapbubble. These were the main ruby's scripts that I used to make this. Oh, also used line2cylinder ruby.
