Swept Blend Edit Vertices

[chughes]

Is is not possible to drag the vertices in the 'Edit Vertices' portion of the Swept Blend process?  I can get the individual vertices to show, but when I click to drag to reshape the blend, the open blue circles change to a solid black dot that cannot be moved.

I need to drag the upper vertices down to create a smoother transition to horizontal

I need to study adaptive families.  I do not have experience with them.  I will give them a shot.

I will need to study up on adaptive families, but that looks very promising.  I will give them a shot.

Oop, duplicated the response.

To potentially close this discussion loop, I have modeled two variants of an adaptive swept blend.  Attaching them here for critique or use.  One is based on a curve, the other on an ellipse.  Both get me very close to what I want to do, but I still do not have the control I want.  The lofting action between reference elements tends to want to smooth the curving too much, with the only remedy being to add more reference elements.  This created other control issues which tended to get exponential.

For the moment I will stick with the simple extrusion + void ellipse extrusion solution.  I may explore an option to make the blend a void and subtract it from the top of a solid.  The form of the top of the wall is ultimately the form I am trying to create.

Below is a comparison.  Extrusion + void is on the left.  Adaptive swept blend is on the right.

Thanks for all the help.  I still want the ability to grab and drag those swept blend vertices, though........

Has this ever been addressed? I am trying to accomplish something similar with a stair railing/wall at the landing, similar to attached photo. I've never been able to achieve a smooth transition at the point where it flattens out.

I still have not been able to get the full result I want.  The extrusion + void solution is nice and smooth, but you cannot achieve the gradual, swooping curve on the top edge.  The adaptive family solution doesn’t get the top right, either, and creates additional unwanted 'bubbles' in plan when trying to flatten the starting edge.

The true solution is to allow swept blends to have more than a single segment in the path.  If a swept blend were to allow multiple segments, a deliberate, measurable form could be created.  I am still searching for the best way to create the form.

By adding an angle parameter to the top of the profile, it is possible to get the top to curve nicely, but getting the start segment to not 'bubble' out is still problematic.
