Right my next headache....

I want to design a wall that goes in and out 3d but its not planar, I can draw the head of the wall which zig-zags the zig-zags get bigger from the origin , and the same at the bottom of the wall but in the opposite direction...........

I've drawn it free-hand but I'm now trying to model it in vectorworks.........

I know its not a great explanation but any suggestions about infilling the wall planes between the head and foot of the wall.

Thanks

Could you post an hand-drawn image of what are you trying to do? Maybe that way we can help you. :)

Hi Chris
Sorry it's taken me a while to get back to you on this. Without seeing this it is a little difficult to work out what you are trying to do... However, with a little guess-work and imagination, I think I can work out what you are trying to do....

Are your walls larger at the top than at the bottom? If so, the sides of the walls are not vertical?

Either way, you won't be able to use the Wall tool for this as the Wall tool by its very nature has vertical sides.

If the tops and bottoms of the wall are to be in the horizontal plane, you can just draw them in plan view (two separate 2D shapes) and place them in the correct plan position with the shape for the base of the wall sent to the back of the shape which represents the top. Then, select them both and from the Model menu choose Multiple Extrude. Enter the Extrusion (in this case, the height of the wall) and it will extrude from the bottom shape to the top shape.

Hope that helps - but please do send a sketch and I'll take a look.

Thanks Tamsin

I can see where you are going with this and although the top is no wider then the bottom they zigzig opposite to eachother and both top and bottom get longer over the length of the wall.... you are right someone said a picture is a worth a thousand words...... or something like that.
But the procedure you have outlined should work to achieve what I want so thanks again....

I have a deadline to meet of next Wednesday which is looming fast so I have done an easier zig-zag which keeps trhe wall vertical ie both top and bottom zig-zag with the same node points.

It looks like you can solve it by drawing the two outlines (top an bottom) and creating a nurbs surface between them. Then create a thickness to the surface.

I don't know how to achieve that, but it looks as a possible approach. hope it helps you somehow.

Are you trying to do something like this?

The length of each wall segment is a fibonacci number. The top and bottom of the walls are mirrored. The angles are all 45. The top gets taller, but that's just linear. (Probably should have made the heights fibonacci numbers too)

It's just a shelled birail sweep loft. There's probably a way to do it that gives a better top and bottom of the wall....
