voilà !

Yes, FFD was perfect for adding the curvature to the bent lattice, thanks cotty.

Since this is practically a tutorial at this point, I will include a render of the final product (really the first of many iterations I have planned for this technique!).

Thanks again for all the help, now I have whole new tool set !

Just to follow up, in the example above I was trying to orient the lattice with the up and down arrow keys.

I tried to bend the shape to a few SU arcs which i welded together, and it worked. So, I thought maybe the problem was the bezier polyline. I then remade the chair curve from SU arcs and lines, welded it together, and get the same problem as above.

darn

Maybe its just bugging out because of the complexity of the lattice. TIG's was uniform and symmetrical. Mine is a gnarly triangulation of points. not sure if that matters.

Thank you TIG. Worked like a charm !

I used triangulate points (by TIG), to create the geometry. Made a series of c-points on a plane using projections tools, (which are great, but for every c-point you need to hit the button again, make c-point, hit button,make c-point, hit button,would be nice if i could just touch the button once and click away) then used lattice maker, then JPP.

One thing I tried was to give the lattice frame some curve (like a chair would have, for your bum) with radial bender from Fredo. When I used that curved frame with shape bender I got a ton of noise (fragments, lines, garble). Perhaps I was asking too much. Flying to close to the sun on wings of pastrami (Seinfeld, anyone?).

Doesn't look very comfortable does it. But then it was just a dry run to work out the process. Ill refine it and Repost the result. I guess ill also need vertex tools to add the curvature to the shape after using shape bender.

Is vertex tools ($) the only option here?

Again, thanks for taking an interest in the thread TIG, really appreciate all the help.

Humph,

Now Im having problems with shape bender. It won't fit my lattice to the shape/curve.

The proxy looks like it should work, but all I get is weird perpendicular positioning. Ill attach picks.

I made the curve with the bezier curve plug in. Its a polyline with arc corners.

Any help would be much appreciated.

TIG

Thank you for your input.

I think between your method, the vonoroi ruby, lattice maker, and vertex tolls I may be on my way!

Amazing, you have time to give us toys and show us how to use them.

thank you, thank you, thank you!

Thank you very much guys!

I will see what I can come up with.

It seems that the example shown from artisan by Pilou (though very nice) will not work for this process, as the hexagons are coplanar before they are given dimension, then smoothed, then deformed.

I think for a chair like this I would have to get the shape from a plane (without dimension/depth), then apply the voronoi geometry, then offset, then joint push-pull. Or at least something to that effect.

I think I could be half way there. Its too bad that the voronoi plugin was not developed into 3d, or onto a yxz plane. Unfortunately it only works on a xy plane......

ahhh so close....

I think I could make something similar with a square, or triangular geometry, but not the voronoi. I think......

Thats exciting!

any chance you can give me some insight on how to get a shape like that?

I imagine starting with a plane of some sort, generating geometry on the mesh of the plane, and then giving that geometry dimension.

Any insight would be much appreciated.

Thanks Pilou

Hello,

I've just stumbled upon this amazing chair which was created in 3d Max.

It made my stomach drop because I could not even begin to imagine how such a chair could be modeled. The organic flow of the shape combined with the geometric porous material.

Is this beyond the capability of Sketchup? Not trying to start an environment/program battle here. Just trying to figure out where to put my efforts if I want to be able to produce shapes with that parametric (is that what that is? just guessing here) geometric thing going on.

I can imagine how to do something kind of like that between the sub-smooth and a ton of intersecting. How ever I doubt Id get that type of result, and the geometry on that mesh is proper (you know what I mean?).

Any thoughts or scripts?

After spending some more time with this, I have come to the conclusion it is the duct design that is the problem. The dimensions of my duct are just different than the posted image, so of course it ends up looking different.

Any comments would still be appreciated though!

BlackCat: I think you would have an easier time using a combination of curvi-loft ( or a simple follow me for that matter) and the 'intersect with' function.

The image shows two cylinders with a bit of an s-shaped curve, which intersect with one another at the base forming a nice flat plane between them. To get that shape I would form one s-shaped cylinder and then intersect the base with a rectangular plane at the appropriate point (this may take some thought/ experimentation) to produce the particular shape. Then form a component from this shape, rotate it, and move it so that it snaps to the other at the appropriate point.

Hope that helps... if my explanation is not clear I can try to upload a example, but it would be my first and i imagine you might get it done before I had the chance.

Anyhoot, good luck, hope that helps.

You should be able to edit it in your text editor. What program did you try to use to open?

Got it!

It was a security issue. I did not have full read/write access for the file. Just had to give myself permission, which i graciously did.

@pjbazel

There is a parameter for fixing the minimum amount of scaling when dragging. Unfortunately, I did not make available for setting in the Default Parameters...dialog box.

I think I will in a next release.

In the meantime, you can modify the line 180 of file bootstrap_FredoScale.rb, which is:
LIMIT_InferenceScale = 0.05
Just change the value, for instance 0.01.

Fredo

Ahhhhh, thank you so much Fredo! And thanks for all the wonderful toys!

One question, I tried to edit the .rb in a text editor but I was "denied permission". Can anyone tell me how should I go about editing the bootstrap_FredoScale.rb???

Thanks for the help.

@dave r said:

I see it too on a simple box. When the scale handle first moves it is either to 1.05 or 0.95. That's really no a big deal, though. If you want a precise scale factor, just type the desired value including 1.01 or whatever you really want.

Exactly, yes that's what mine does. Very frustrating.

yes, I can type it in, but this is not as useful as there is no real-time feedback/deformation. If its possible to change it I would love to know how.

Also, possibly more urgent is that fact that in target mode this 'jump' prevents the operation from occurring at all. Neither draging the handle, or typing in parameters produces a result when scaling in this small range.

Perhaps its a script issue?

@gaieus said:

Can you share the model file (or at least the problematic part) you are working with?

I could upload a file, but Im not sure it would help. This is the behavior all the time. There is not particular file or problem area. It behaves like that all the time.

Should I upload a file? Will that help?

Again, its only with the Fredo Scale, not the native scale.

Let me know if you think it will help ill post one, but it appears to be the script, not a particular file/operation.

Thanks for the help guys

@gaieus said:

Hm. I tried both with the native Scale tool and FredoScale and I can easily move my mouse in a way that it smoothly "grows" the numbers by 0.01 increments.

When I use the native scale tool it scales by .01 increments. But, when using Fredo Scale it jumps to 1.05, and then scales up from there at .01 increments. Very frustrating. There is a similar issue when using target mode with small (not minute, but small) distances.When using scaling handles I can type in the values between 1 and 1.05, but with target mode there is no way to get the scaling through the small distance.

If anyone has any ideas please tell me what you think. There didn't seem to be anything in the settings to correct this.

Hello all,

This is my first post, but I have spent countless hours reading this forum and it has been the the most amazing SU resource. Im just learning, and I would have a fraction of my current knowledge/ability without this forum, not to mention the developers who make scripts for SU (thank you Fredo!!!) Im amazed how much effort and energy the individuals in this community are willing to give. Truly amazing!

I now have my first question, or at least a question I could not answer simply by reading. I tried to search for the answer, I did not find it, but im sure its simple.

Using Fredo scale box scaling, when I grab/drag a handle and scale it jumps from 1.0 to 1.05, and I can not get it to scale in this range (1.0-1.05) without typing the values. It would be very nice to stop this, and have it scale in this range without it jumping from 1.0 to 1.05.

Is there a way to change this?

thanks...
