Can Anyone Make a Curved Lattice Panel ?

[JJohnson]

Trying to draw one for this trellis under design.

Builder wants to cover the arched arbor with plastic lattice panels that would
take on the curve.

?????

That is something you would need to do in Sketchup or Rhino. Why not just place 4' sections and then rotate each one to match the curve? You could try 2' sections if you want a better arch, but in construction that is typically how its done anyways. Bending pre-fab lattice would end up breaking apart.

Not that this is the question, but that builder needs to look at the time/cost of bending those beams. The design, though it can be drawn, is highly "improbable". I did an old town arch in Anacortes, Wa which initially the City Council wanted glu-lam beams arched - and we ended up as I suggested from the start in using steal webbed members. I would be interested to know what you guys considered for actually building that. Thanks!

You can make it from a curved railing.
By simply making a symbol and rotate it about x or y acording to your orientation. actually infinity ways to do that in ca, but you already made a lot similar railings as i can c from the image posted.
copy it in new plan and rotate accordingly

Jere,

Looks like you already have all the items setup to do the job.
Copy, move, resize and multiple copy the curved beams for one way.
Do the same with the top pieces to get the lattice members going the other way.

Post the plan with the specs for the lattice and i will have a go.

Glen,

Plan is attached. Done in X4.

Builder will make a laminated arched beam using redwood 2x8, three layers, sawn into the radius, bolted up, sanded. It will not be carring much weight, just 2x joists (I guess you could call them), supporting posts @ 12' o.c., and the lattice panels over. Idea is for Wisteria to take over in time. I was able to figure the radius with Chief, and a simple diagram.

Second Try

Consider Lexan Thermoclear to the lattice. It will look much better and have the added value of rain protection. It would bend in that situation fairly easily.

Good idea Yusuf, and I am assuming the symbol will appear correctly in plan view........ I will give it a go when I get a chance.

Here is a diamond grid lattice panel that is a symbol converted from a window in a curved wall. The lattice pattern is created from diagonal lites.

Windows can only be 24'-0" long; so the panel the OP requested could be made directly into a symbol using two windows, or it I could make half of it as a symbol, and then reflect it for the other half.

Looks like it to me !

Jere,

Are you OK with the lattice now?

Just some points on what you have done so far.
The curved beams are really faceted, ie., they are made up of straight sections that are really obvious.
I suggest that you convert them back to a plain polyline and use the Convert Selected Arc to Polyline tool.
You can specify a greater number of sides to make the curve smoother so that it reads more like a curve than straight segments.
Then reconvert them to a Polyline Solid.

Wouldn't it be better if the joists were then build radially sitting on the curved beam instead of being vertical?

I like Bill's lattice but haven't time to try it yet. Thanks for suggestions, I kept loosing the beam when trying to convert it / reconvert it
etc., but was able to start a new one from scratch, and with 60 segments rather than 6, they look good. I will rotate the joists when I figure that out. Plan so far is quick sketched to give owner preliminary views.

Thanks again everyone,

Bill, would you mind going over the steps you made to create that cool symbol.?

Thanks,

Hi Jere,
I'm just leaving for an open house, but will try to go though the steps for you sometime this weekend. Have you done any symbol creation? What is the exact inside radius of the lattice? Are you using X5?

Looks like a good weekend to be out on the Harley.

Bill
