I have a curved/twisted surface (as pictued) on which I want a truss to run along. I took the surface, squished it, and built a truss for it after I had success with OrientOnSrf to map a smaller truss.
I can’t seem to correctly orient the truss on the surface or get it to twist as shown in the Rhino 5 help guide.
Is there a better way of going about this, or am I missing something obvious?
Here are images showing what I have and the best I’ve gotten:
_OrientOnSrf
will move and rotate the picked / selected Objects to align locally to the surface.
Like the local Coordinate System you see with the
_Dir
command.
You can imagine this command like a flexible clothes for example a shirt (the target Surface) with stiff knobs (the objects you are aligning)
if you also want to deform the objects you might want to experiment with
_FlowAlongSrf
But this will give you more Design-Data-Quality. And in most cases your bars will not longer be straight.
For _FlowAlongSrf you need “raw” objects (not blocks / instances). As simpler the input geometry the more expectable the result will be…
