3D Spline question -

[jon46XEC]

Puzzled here - This spline is constrained as tangent to the projected line. Now I am trying to adjust the tangent handle but it does not want to be dimensioned and just gives a red error. Thanks - JD

Spline needs to be blue, if you make the other end tangent, does that unlock it?

[jon46XEC]

Nope - its blue before the dimension goes on, then changes to black like always - but won't adjust the length and turns red.

hi @jon46XEC 

please submit this work as an f3d file. but first try the pink line with a right click and the selection release to get the link in blue. for me it is not really clear whether the spline is tangential or just the green handle.

i am happy to see this work.

Thanks for your help guys, but I deleted the sketch and started over. Repeated all steps and it worked successfully. Not sure what caused this error before.

You don't need that many splines to define that loft. As a matter of fact, you likely only need two.
