T-Splines 2.3 Grasshopper component

[TomFinnigan]

So, T-Splines 2.3 is now compatible with a small grasshopper component that I made.

This is a fairly rudimentary integration compared to what is possible, but since Grasshopper is still under such active development we didn't want to spend too much time doing a deep integration.

The main file you need is TSplines.gha. This needs to go into your Grasshopper components directory. It creates a new node in the mesh tab that converts directly from a Mesh to a B-rep, via T-Splines.

I made a short video on how to install and use T-Splines for Grasshopper.

Here's a video showing a more complex example.

You'll also need T-Splines 2.3, and Grasshopper 0.6, 0.7, or 0.8.
Here are links to TSplines.gha for various versions:
T-Splines 2.3 component for Grasshopper 0.8
T-Splines 2.3 component for Grasshopper 0.7
T-Splines 2.3 component for Grasshopper 0.6

The component is very simple. In case it's helpful, the entire source project is also available for download.

Let me know if you have any questions.

If you're looking for the T-Splines v3 WIP Grasshopper component it's here.

Hi Tom

I tried your approach on a more complcated shape, and it worked perfectly.
Attached is a picture of the result.

It can also be very effective to build meshes in Grasshopper and use them as a basis for TSpline models.
In this case, I found the Rhino command AlignMeshVertices to be very helpful, since you sometimes end up with small deviances after Grasshopping
I have to say, your video example is nice, and this was very fun to try out.
For grip-patterns etc on products this is very useful.
Next thing i'll try is to import this model into Spaceclaim and see if I can work further with it there...
Keep it up!!

[TomFinnigan]

Cool.. . Let me know if there's anything that would make the component more useful.

Hi Tom
I download your component yesterday, but it didn't work. The output were allways "null".
Is there anything wrong in my files?
Hope to receive your quick feedback~!

Your network looks like it's set up properly. There are a number of things that can go wrong, and I was lazy and didn't put diagnostic error messages into grasshopper. I'll add some and post an updated component soon.

One thing that might be the problem is that you need a full license or time-limited trial to work with the grasshopper component. We recently switched to save-limited, but that didn't make much sense for grasshopper. If you want to do a time-limited to test out grasshopper let me know.

If that's not the problem, I will try to add diagnostic messages to the grasshopper component soon.

[TomFinnigan]

So I added a debugging message output to the grasshopper component. The links above are updated to the new download.

Connect a panel to the dbg output of the node and let me know what it says. Also, you might check the command history window in Rhino, because the plugin sometimes outputs errors there.

Thanks Tom!
I think you are right. My TSpline is a free trial version.
"A time-limited to test out grasshopper" sounds great !

Here is a picture from some more grasshopping.
I think this would be a nice pen-holder

Some more Grasshopper experiments today.
These are just cylinders, but I'll try to make some more fancy ones once i got the basics set up...

Very neat, Fredrik! Thanks for sharing your experiments.

hi
is there a possibility to get access to other commands maybe the bridge,tspline from control polygon
or crease,...
maybe you can guide me, btw great solution with the invoke
thx

Hi Tom,

Can you help me with wbjoin?

Where can I fount it?

Thanks

hi!
please, can you update this component for grasshopper 0.7?
it will be awesome!

[TomFinnigan]

Updated the component to grasshopper 0.7. Download links above have been updated.

One change I made was to move it from the mesh tab to the extra tab.

[fredrik]

Thanks.
This will be fun!

Tom,

with the latest version of rhino WIP v5 (09/29/2010) the component for 0.6 version of grasshopper is not working anymore. Do you have the same issue?

thanks

Hi.

I wanted to try out T-Splines with Grasshopper but am currently using a demo version of t-splines. Is there still a way to get the alternative demo version which will work with your t-splines grasshopper component?

Thanks

I bet this is due to how we find the T-Spline rhp file. I recently discovered a more robust way, let me see if I can get you an updated component.

Also, is there any error message? It would be helpful in diagnosing the problem.

I sent you a 30-day time-limited trial key, which should work with Grasshopper. I just wanted to reply here as well in case other people had the same problem - if they send me an email at tomfinnigan (at) tsplines.com and I'll send them a 30-day key.

Stephan,
I made some modifications to the plugin. See if this new version fixes the problem..

[OnOff99]

Thanks Tom for your support I think the issue was not coming from the plugin but Win7 UAC. The file has been blocked by windows. I had to unlock it just after having taken full controll on this file. However I will test your new component to see the difference with old version.

Thanks again for your support.

[TomFinnigan]

Just a quick note, updated the 2.3 component so that it works with Grasshopper 0.8

[TomFinnigan]

Another quick note, there's a more powerful T-Splines Grasshopper component available for T-Splines v3 WIP.

Are you looking for something in particular? What type of surface would you like an example of?

[steinyuer]

hi tom, i download the T-splines 2.3 Grasshopper component, and setup like you've taught in the video. But it doesn't work. It SHOWS: Error: Unable to call tsMeshToBrep, requires a full or time-limited license. Email support@tsplines.com for help. It means i need some license?? Could you please send me? Thanks,thx, thx+++
