2 Rail Sweep question

Post by Onetrack »

Hi all, I have created an object using a two rail sweep and I'm wondering if this can be modified to produce this curve also. At the moment the edge is vertical, not curved (see attached file).

Thank you, Onetrack.

I'm not sure about your question. Maybe something like this? I used the same rails as you did with 2 profiles. One at each end.

I created a fin/tail using a 2 rail sweep as per the attached file. Can the 2 rail sweep, or another method, produce the curve as well per the screenshot?

You can do it by adding a second sweep with a multiply combine mode. Please see the attached file. I set the rails at the end of the shape and created a sweep vector that is exactly 1mm tall except at the end where it needs to slope down. The way it works is that when you combine the components, the height of the existing fin component is multiplied by the height of the multiply sweep. Since most of the sweep is 1 unit tall, it is multiplied by 1, until you get to the end where it fades off.

For what it's worth, this can also be done by making a second sweep with the "Low" combine mode. It will probably leave some extra bits of component that will need to be cut away, but that's not difficult. Often more than one way to do things in Aspire.
