Large circular lattice work
-
Hi guys, my name is Cliff. I've been a casual SU user for about 2 years now. An early project I started was a 14' Yurts or Ger. The 1st go round I spent a couple of months trying different way to draw the Khana (wall) of the yurt. So what it is, is a large lattice work wrapped around a circle. Each piece of the wall is 1.5"x.25" that's 96" long. There are about 60 of these pieces, bolted together so there collapsible, but when standing to make the tent, are at right angles to each other. The tent is based off of plans from a pdf called "yurt_construction_document.pdf", I'm sure it's still out on the web somewhere. I've just redesigned the door frame and had to redo a few rafters to make the door work. So now I want to tackle the last big head ache, the walls.
I'm hoping some of you guys who have forgotten more about SU then I have learned can give me some idea about how to draw this. I've checked out the warehouse and the best example had 2-d planes for the lattice. I want to try to do it with 3-d pieces. I've downloaded a plug-in by Fredo6 that allows me to draw on curved surfaces, but I'm having troubles with it as well. I've also tried Chris's Shape Bender, but it locks up the program every time I've tried it. If I need another plug-in, learn to use Fredo6's or Chris's plug-in better, or it can't be done. That's what I'm hoping to find out.
Thanks

It would be nice to see a photo or a drawing of the frame work but I'm thinking you could use Draw Helix and Fredo's Loft or TIG's Extrdue Tools to make the actual lattice. I would make a single lattice as a component and copy it around the center of the yurt . I did something similar to create the baskets on these wrought iron spindles.
In your case I think you would need only part of one turn of the helix and after you make the first one, you can flip a copy of it to make the crossing one.
Maybe I can get a little time this evening to draw something to show you what I mean.

Let's see how this works,
I didn't have a pic of the frame work, but found this on the web.
It's from this web site

Sort of like a pantograph, or scissor lattice.

Would something like this play?
I could have gotten the ends of the slats closer together but it's just a quickie.
-
How the bloody 'ell did you do that!!!!! That's it.
Now I know I need to learn this program better.
Please, a detailed explanation. Thanks Dave, that's great work.

Not exactly the same but an anthology thread
I remember that I had made that
An another concept
Take a photo of your subject or a texture then use the shape bender by Chris Fullmer -
Alright. Let's see if this helps.
- Use Draw Helix.rb to draw a helix. I set the radius to 8 feet and the pitch to 48'. I don't know what either of those should really be but this gives the idea. I also set the number of segments to 72 so that there'd be more than a couple of segments left after getting rid of the unneeded part of the helix.
2. My yurt walls are going to be 8 feet tall so I drew a rectangle at that height above the ground plane. this makes it easy to determine how far up to cut the helix.
3. Explode the helix group and draw a little line segment that intersects the helix and lies on the cutting plane. I missed the screen shot for it but delete the helix above the cutting plane, the little line segment and the cutting plane itself. This leaves one long edge of the slat.
4. I used a guidepoint at 1-1/2 in. to identify where the other long edge of the slat will fall. Then I selected the helix and Copy/Rotated it that far.
5. With the Line tool, draw lines to connect the ends of the slats. Divide each of those lines into three segments and then use Weld.rb to weld the three segments together. You could make the ends of the slats with arcs or dog-eared like the ones in your photo. Next I used TIG's Extrude Edges by Rails from his Extrude Tools to create the skin for the outer face of the slat.
6. I gave the slat thickness using Joint Push/Pull. You have to select Thickening before extruding with this plugin. At this stage one slat is complete. Make it a component (not a group).
7. Select the slat and Move/Copy it out the thickness of the slat.
8. With the copy selected, right click on it and choose Flip Along>Component's Blue. Then use the Rotate tool centered on the origin to rotate the slat into a better position. This time I brought its bottom back to align with the bottom of the first slat.
9. Select both slats and copy/rotate them through the desired angle. I took a WAG and used 10°. Hit Enter and then x35. This creates 35 additional copies (not including the original ones) of the slats.
10. Finished. ready for the roof and coverings and it's ready for occupancy.Actually you'll still need to make the door for the yak so decided where it will be. Make the components in way of the door unique so you can edit them to cut out the opening without removing the entire bottom of the yurt.
The plugins I mentioned should all be in the Plugins Index. Look for the red button at the top of the page.
I'm sure this looks difficult but it really isn't all that hard. I expect you would spend more time figuring out what the pitch of the helix should be than actually drawing this.

Interlaced will be cosy

Interlaced would be cosy but that's not how they are in the photo and if they were, they wouldn't allow the lattice to collapse for packing onto one's yak for the trek to the next valley.

Sure

I feel like that when my family goes on a trip.

Pilou, I've tried Shape Bender. I had the complete wall drawn out, flipped to vertical, had matching lines, straight to arch (with in .25") tried as components, component, as group, as just made group, and every time the program (SU) locked up. I know Chris did a 9 meg car with this and the wall section is NO WHERE near 9 meg. I thought I had it made and after 4 nights of fighting it, I decided to ask people here how they'd do it.
Dave, THANK YOU! I would have never thought of using the helix, I've been looking for the plug-in but got side tracked checking out tutorials by sdmitch and still have to find it.
I have built 2 of these yurts, a 12' and 14'. But I never did like how the door fit. To be blunt, I didn't like the 1 size fits all crown and the roof canvas detail either. After camping with the 12' for 1 year. There was 2 things that stuck out the most, it was 2 small for what I was doing and I hated the door. With both those yurts gone (sold off), I was thinking of building another 1, but not till I had redesigned the door (done) and then I just HAD to draw it out exactly as I wanted to build it (more gray hairs, lol).When I get it done, I'll upload the files so you can check it out.
If anybody has any other ways of doing it, I'd still love to see how you'd draw it.

You're welcome.
Sometimes the trick in SketchUp is figuring out how far down to break something before you start drawing it. Coming from a woodworking background, my usual approach is to draw individual parts and I nearly always draw them in situ so that I can use parts I've already drawn as a reference. Anyway, when I was thinking about your problem, I didn't really see it as a lattice of slats that are assembled and then bent to make the cylinder. I just saw a single slat going up around a cylinder. My experience in teaching SketchUp is sometimes we can get hung up on something relatively simple and have a difficult time changing tacks.
Anyway, here's a link to the Draw Helix plugin. I guess it isn't linked here on SCF. Sorry about that.

I don't know what I can say
Here it's 48 kb
Maybe you must use a tiling texture, that I don't verified
Or make the module as same size than a segment of circle

Dave I did find it through a forum search, had to add .rd and it showed up. Moved it to the plug-in folder and "nothing". So I'm uploading 2 files, 1 on ver8, 1 on ver6 for Polou. This is the file I tried to use with Shape Bender. Maybe you guys can see what I'm doing wrong.

Thx but
seems it's always Version 8 !

Pilou, you are a dinosaur. I think we'll collect some money for a new computer for you in BaseCamp. If you are lucky, we won't spend all the money on booze.

The new-improved even better tool
DrawHelix**14**[by Jim] is linked here http://forums.sketchucation.com/viewtopic.php?p=292183#p292183
That appears in the 'Draw' menu NOT 'Plugins' !
