I swear this was awesome just prior to Rhino Crashing!  Crash had nothing to do with Exoskeleton, I just had too much stuff going on on my computer. 

Seriously nice contribution dudes!

Hi Guys,

That's very very helpful (and I like the christmassy red on the printscreens). Thanks so much for sharing your work. I just gave it a try with a basic wireframe extracted from a mesh and got the results below. What am I doing wrong?

Best wishes,

Arthur

Sorry, here are the files:

Rhino

GH

Nice tool to simplify work :)

Thanks - its odd, but that file works fine when I open it.

I notice it is saved as a Rhino4 file - what versions of Rh/GH are you using ?

Ok, just checked, and it seems there is a bug which occurs when using it in Rhino4, but not with Rhino5... we will dig into it

You are right! It works well with Rhino 5 :) Great stuff.

Awesome work! Thanks for your contribution!

Super fantastic!!!! Faster and more flexible than T Spline Pipe!!!!.... Thank you for the tool....

GREAT WORK!

Awesome tool.Thanks!!

:D ?????

amazing work guys! here is a little suggestion: wouldn' it be possible to intergrate surfaces into the exoskeleton? to combine line-like typologies with surface-like ones..

I was just thinking about a need for this. Many thanks for this new tool.

Hi David and Daniel,

Really nice component.  I noticed how the cross section is rotated along the length.  I assume this is to create nice triangulated meshes?  It would be nice to have the option to maintain the orientation of the cross section (possibly with quads), or even not require any divisions along an edge?

Just in case you did any updates!

All the best

Harri-

Yes you're right...the polygons along the struts are alternately rotated to create symmetrical triangulation.  It would be possible to allow for them not to be rotated/develop quads in the struts/not require divisions...I guess the one concern would be that quite suddenly there will be so many more options for input!  But maybe it could just be a "simple strut" boolean that implements all of these at once.  But it's totally doable...there are some other adjustments we're looking at as well, including the hulling, how the "knuckles" behave, and possibly examining "charge" options for variable thickness along the struts...Christian's request for tying in surfaces is something else that's been on my mind as well...it's a slippery slope!  We'll see what happens...

hey Guys,

as you can see in the attached picture i run into the problem that the exoskeleton component connects some parts to the 0,0,0 coordinate.

where is the problem? any idea?

I am not seeing exoskeleton in the mesh > triangulation menu. I copied the component into the special folders > components as per usual installation of new components. What am I doing wrong? I've tried Rhino4 and Rhino5 (32 and 64 bit) versions. Grasshopper is version 0.9.0014

-Thanks in advance

@ daniel: right click the file and choose "Unblock" 

Thank you Patric, that worked.

Hi Guys,

Looks like a great tool thanks for sharing! I seem to be having trouble with using it in Rhino 4 though, getting the same bug as reported earlier. I also don't have access to any Rhino 5 yet either, do you think you will get it working for Rhino 4 at some point? Seems like a sign to upgrade I think...

Great work!

Looks pretty amazing.
Any news on the Rhino 4 bug?
I am having the same issues like already reported ones, on Rhino 4 SR8

Hi djordje...haven't yet taken a close look at why it doesn't work in R4...I'll try to get to it soon if possible!

Understood. Sorry for disturbance.

Hello

Is there a solution to patric guenther's problem?, I am running into the same problem repeatedly.

Thanks

http://www.grasshopper3d.com/forum/topics/exoskeleton-lines-to-origin

I tried using this on edges from a diagrid created with lunchbox, but when I add the curves (that comes from a dupborder on the panels) to Exoskeleton I get the following error. Error: Solution exception: Arithmetic operation resulted in an overflow." I tried with closed curves, exploded curves, fewer curves.. Any idea what could be wrong?

Hi,

Is Exoskeleton ever likely to work with Rhino4? It looks really useful and something I'd really like to experiment with, I just can't afford to upgrade to Rhino5 at the moment :(

I get the same problem as described in this post re: flattened meshes http://www.grasshopper3d.com/forum/topics/exoskeleton

Keep up the good work!

GREAT JOB!!! The combination with Topologizer .... great!

Very nice tool! thanks alot!!

Are there plans in the near future for an update that allows different thickness per line? I'm using offset mesh right to change the thickness but the results aren't very good.

Nevertheless, great plugin.

Hi Vicente-

I am working on just such an update this moment...In the short term I am looking at making it possible to locally alter both strut thickness and node offset distances, and hopefully will have something in the next several days.  Additionally, a key component to this update is that node thicknesses will be better adjusted...currently, the node size is determined by either the node depth assigned by the user, or by the minimum offset required by the narrowest angle between struts in a node as a function of the strut thickness.  The update will allow for the node offsets to shrink locally for each strut. In the longer term I am also interested in looking into mesh self-intersection for the purposes of making more organic meshes...but that's not for right now.  So you can expect an update soon...

Unfortunately, we won't be actively supporting V4...we haven't been able to identify what the bug is, and we are working to support 0.9.0050+.

I also hope during this update to address the issue of the lines running to the origin.  The reason for this error is pretty simple: the nodes are generated using a convex hull, and when these hulls overlap...which is to say, when any hull engulfs one of its struts entirely, the mesh breaks down.  One way to help prevent this from happening is to use Daniel's topologizer, but that won't always work.  I am hoping to implement some changes that will either generate "super nodes" that combine the input struts between highly proximate nodes, or at the very least generate a detailed error message that illustrates where the input is causing the breakage.

Is there something wrong with my sets? The left is the original lines set, the right is the exoskeleton result, which add some lines from 0,0 point to some of nods.Where are the lines from?

Hi Kyle. Check this topic.

Well done mates. :)

Hi guys,

This is such an amazing tool, I've had absolute nightmares in the past trying to do this type of thing! I'm having an issue where some nodes separate from their struts, do you have any idea what I'm doing wrong?

I am very new to grasshopper and am trying to make these lines into meshes. Although I seem to only be getting triangles and the corners of the lines which is not what I want.

I don't know if Arthur Mamou-Mani or anybody else is able to help. Thank you. 

Hi,

Thank You for sharing this awesome tool. Unfortunately, I can´t get good clean results. It computes strange exploded surfaces, which do not connect to each other. What am I doing wrong? I have tried a lot of values settings and still get somtehing like this:

Here is a definition and source file.

Thnx in advance for respond,

with respect,

Ondrej

Excellent tool,from a visual standpoint.

 I've had issues with a model when trying to create a 3D printable object.

Basically, I had a 2D wireframe mesh  and used Exo on it, looked really good, but, once imported into Shapeways, most of the elements disappeared and I was left with a very "skeletal" model.

What I ended up doing was much simpler, I split the mesh into lines and then used the Pipe tool.

Hi Mihai-

With this release of exoskeleton there is an issue with lines that are located in the world planes...so if you have a 2D wireframe that is located in the XY plane, the mesh will look fine, but it will have several naked edges. This is an odd artifact, I think having to do with decimal places and translating between Point3d geometries and mesh vertices...but basically, if you want to make the mesh airtight, you just need to move your base wireframe network out of the World XY plane. Hope to fix this in a later release.

Thanks David, I will give it a try in the future on more complex and three dimensional meshes.

Hi,

First of all thanks a lot for your work!! Ive been struggling to print a diagrid on a building, and joining each pipe was giving me a hard time, as that wouldn't work.

When i enter all the curves into the script I get an overflow error.  Is there a way to get through it?  Joining lines maybe?

Thanks a lot for your time

Maximo

really impressed with this! thanks for sharing your work!

Dear Daniel and David,

I would like to ask, did You figured out the overlapping nodes issue allready?

Thanks in advance,

Ondrej

any idea to solve patric guenther's issue? Same thing with me.

Dear Daniel and David,

I would like a sphere like the first image that you posted.

Is it possible to send me some key words to help me.

thank you in advance

Hi Lina- There is actually an updated version of exoskeleton that allows for a little more control of a few parameters: http://www.grasshopper3d.com/profiles/blogs/exoskeleton-cytoskeleto...

Also, you will find some example files there for download...in the complex examples package there should be one for a Radiolarian that you can play with. Good luck!

For download and support for the latest version of these components, please go to the Exoskeleton group page here:

http://www.grasshopper3d.com/group/exoskeleton

Thanks, I will definetely download it.
