Marionette - Nurbs Curve

[gonzalezj]

Hello,

 

How does the Nurbs Curve node work in Marionette? I currently have an ordered list plugged in, a Bool to make the Nurbs Curve tool false so that it interpolates between the provided points, and a Real node with the value of 3 for the curves degrees. When i run the script I get an error with the Nurbs Curve node. Are these the incorrect inputs? Any recommendations welcome. 

 

Thanks!

Can you provide a file, if not, could you provide a screenshot of your error message?

 

Thanks!

Sure! Screenshot attached below.

Alright, so at a first glance, the most glaring issue I'm seeing is that you're using "Point2" nodes instead of "Point3".

 

I can work on getting a change in where that won't matter later on, but for now try using Point3 nodes with your Z set to zero (assuming that's what you want), and let me know if that works any better.

It worked! Thank you so much for your help and prompt responses!

No problem! We're usually pretty quick on the forums  

 

Let us know if you need any more guidance!

... Just as a quick followup, the Curve node in this file should accept 2D points as input...

Great thank you! Follow up question... I created 3 Nurb Curves and am now trying to loft them using the Loft Surface node. I am able to run the script but no resulting surface appears. Is there a node I am missing? 

[Marissa Farrell]

If you haven't already, you need to include a "group" node in your network.

 

In my following example, I didn't use the ordered list node, but if you have a particular order you want your curves to be lofted I would advise using one.

Oh! Placed the links in the wrong input. Great! Thanks again!

Hi, attached are a few lofting examples that may assist. HTH
