Any way to tweak Sweep option -> ends?

Hi

Does anyone know if it is possible to tweak how aggressively MOI forms the pointy ends if you select that option when performing a sweep?

I like the merging in effect, see 'cowlings' on attached image, but it would be great to have it apply more gradually or restricted more to the end region.

Thanks
Andy

Hi Andy, can you post the rail and profile curves you're using to do the sweep, and also the main body surface that they're on?

A couple of possibilities might be to put in a scaling rail to guide the shaping instead of using "pointy ends", or maybe draw in some curves from the side view of your body, use Construct > Curve > Project to project them onto it and then use 2 rail sweep instead of one-rail sweep.

The endpointselect option is sweep factory input 4, with the factory in C code, so the simple answer is no, IMHO.

However, the sweep has history, so after the pointy sweep is made, either or both ends of the rail(s) can be extended to
a newly placed object. History then widens the tapers, so the new sweep can be trimmed to its original length, with a
larger radius. This is one simple possibility, with only limited testing.

Hi Michael,
Attached is example of what I used. Projected line on to spheroid to use as rail. I initially tried the scaling rail approach but found it very fiddly, as if you duplicate and rotate the main rail there will be small sections at either end that aren't covered by scaling rail so you get a step. If you try and adjust for that I ended up distorting the curve shape.

I have had a quick go with your suggestion of a 2 rail sweep, with maintain height off and a bit of tweaking I think that may do the trick!

Thanks
Andy

Thanks Andy, if you can't get a good result from the 2-rail sweep please post the 3DM model file of those objects in it too. That makes it easier to maybe try out some different approaches.

In case anyone else is looking at the same thing I had chance to go back and try a two rail sweep properly and it works a treat! see image.
