      Hello everyone!

      I would like to know if there is a straightforward approach for extruding along two tapered rails an object that is rather unusual in shape?

      I have two cross sections of the part, but those sections are taken not at the ends of the part. I can easily create a surface between those two faces using Curviloft, but is there an easy way to pull them further? I know how to do it manually, but it's hell of the work while curves are made of so many segments.

      Example

        Depending on what you want, you might try selecting and moving the end. Or you could extrude with Push/Pull and then scale the end. Might be that the native Scale tool or Fredo6's FredoScale would work, too. If I were going to do it I would just make it the full length from the beginning and not screw around with editing the shape after Curviloft.

          Thank you for an advice! But I tried those options already, unsuccessfully.

          I need high precision, and this part that you see already - can’t be distorted. It has to be extended in perspective. I can’t scale and move because part is not going to end up right. If I’m thinking right - ends of the finished part are not just scaled down cross section (at least one of them)

            This is a scaling approach to complete.

            If you double click the center line with Tape tool it will generate a guideline which follows the normals.

            Now you can scale your profile accurately

              I think the best approach then is to model it at the correct length from the beginning and avoid introducing errors by modifying the incorrect shape.
