T spline API in Fusion 360

[moistwood_cao]

Hi guys! I want to create a script in Fusion 360 to control my T spline model, but I cannot find any API about T splines in Fusion Help...... Can you guys do me a favor?  Thanks a lot!

By the way, is there any NURBS tools in Fusion 360?

Hi @moistwood_cao 

Below I am quoting one of the Fusion 360 members from 2021.

"Unfortunately, I don't think the API for operating the T-spline Body is open to the public.

In the past, there was a discussion in the Japanese forum about using the API to manipulate the vertices of a T-spline body.

At that time, I searched the web and found this document.

It was too difficult for me to understand.

Also, I found this package on github.

https://github.com/GrapeTec/T-SPLINE 

There is a tsm file in the rhino folder.
I imported it with this add-in that I have published, and it seems to import correctly.

https://github.com/kantoku-code/Fusion360-TSplineBodyDoorway 

I think the format of the tsm file in Fusion360 is the same as the one in this package, so I think it may be possible to use it."

Hope this helps in any way.

Wow thanks a lot! I am reading a lot of documents about T spline and NURBS. Say, the T spline Tools seem hard to parametrize the model. In github I found the GrapeTec T spline too. This project focuses on the T spline kernel based on 3 layers and used in Rhino. 

Maybe the github is a solution temporarily，or tuse parametric modeling to control points on the T spline 3D Mesh.

Anyway, thanks for help!!!!

I am glad that we found a solution (at least temporary).

Have a great day.
