Large circular lattice 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' ! -

Did you restart SketchUp? Did you look in the Draw menu?

Yes
But I never understood why people don't save all their files posted in V6
Like this all can reload them (v6v7v8)(except when it's Dynamics components (1%) so V7 -

Who is this "all" you talk about. You're the only one left using V6.

I just replicated this without a Helix tool at all...
All done using native-tools [from a plugins-meister
]...Make a cylinder the size of the yurt's perimeter wall.
Center its base-circle on the origin for easy use later
I used 24s [the default for a circle] giving 15 degrees per repeat.
Modify the cylinder with the Smooth tool so all of its edges show - now you have a set of rectangular 'panels'.
Group the geometry - we want to draw over it without our new geometry sticking to it.
Draw a short horizontal line along the cylinder's base-edge, the length of a slat-width [50mm?], repeat at the top join the ends to make a 2d outline of an angled slat.
PushPull the slat to the required thickness [25mm?].
If needed orient the faces so they are all facing 'out' [i.e. no blue showing].
Select all of its geometry [treble-click] and make a component of it called 'slat' or similar.
Replacing the original geometry with the component-instance.
Now make a Rotated copy [Rotate+Ctrl] of that slat about the center of the top edge of cylinder's panel on which slat was formed, locked to the blue-axis.
The copy will now cross the original in the opposite direction, with them just touching.
Erase the cylinder - we now longer need it.
Select the two slats ans use Rotate+Ctrl to make the radial array.
Center it on the origin locked on the blue-axis.
Pick any point and start the rotation of the copy.
Type in the repeat - it needs to be a multiple/division of 15 degrees [360/24] used in setting out the cylinder's panels, I chose 3.75 so there are 4 slats at an angle in each 15 degree 'panel'.
Type that in and the copies appear rotated by that angle.
Now immediately type in the number of copies needed for a full circle - in this case (360/3.75)-1 = 95 since the original '1' is already there!
All of the slats are formed around the shape with proper lapping.

@Dave
Don't think that, we are more numerous that you think! -
@ Dave, I might have been using SU for about 2 years now, but I still have a lot to learn. I just learned about plug-in 2+weeks ago and as you can see, I'm new to the forum. But I didn't know where to look to see that
yes it's loaded into SU. So after I finish my next attempt at a slat, I'll start working on that plug-in and figure it out. I think I've figured out a way to do a slat with all native tools.@ Pilou, Sorry I thought it would work and if I had tried this 3 weeks earlier, it would still be in Ver 6. I just upgraded to Ver 8. Great picture of the yak. I know how Dave feels about camping. I feel the same at times.
@ Gaieus, nice to see you again.
@ Tig, love your forum name, my favorite way to weld. I just saw a vid on Utube from a guy in Japan doing a spring. Which gave me some good ideas to try. Which I'm about half way through now. I came back to double check how Dave did his ends and 'olly zhit I got tagged. I'll be going back over your post, hopefully after my current attempt pays off and not to bale me out of trouble.
I want to thank all you guys for your help. It's really help to cut down my learning curve. I hope you all stick around for the next project, A rapier hilt. I've attached a pic of 2 that are important to me. The one on the right is the 1st hilt I did that balanced out right and taught me how balancing works. The one on the left, I did well going through postate cancer treatment. It gave me something positive to focus on.
