Trouble controling a T-Spline with sketches

[CGPM]

I am creating a "worm" with T-Splines and the tail is created by sweeping a sketch profile along a sketch spline.  I then connected the tail to the body with Bridge and modified the other end of the tail to close it.  Now I want to change the tail by modifying the sketches used to create it, but this is not working.  Is it possible to control the T-Spline body through the sketches?  If so what am I doing wrong?

Thanks in advance for everyone's help.

Hi @CGPM,

Unfortunately, no, it is not possible to do this.  TSplines are not "parametric" features in Fusion (although Pipe is kind of associative to the sketch until you change the pipe with Edit Form).  A TSpline body is really a "direct modeling" feature.  So, the only way to change a TSpline is to use Edit Form (and the rest of the TSpline tools).

You could try to create the tail shape with a sweep along a spline and then use a number of lofts between profiles to create the head. then you have very nice control over the tail through the spline.

Thanks but there is way more going on with the body than my example, think salamander with legs and the lot.  This is a soft bait for fishing so the tail action is critical.  Rebuilding the tail to make adjustments isn't a big deal, I have already done it a few times.
