How to create a sweep with short path?

[Sleepingfish_Kuo]

this is orginal model, And I want this below.

Is there any other method except rewriting it as an extrusion component?

Hello,

How about using swept blend? If you have two different cross sections and a path, you can create using swept blend. You can also use void for cutting unrequired parts from the top or section views. 

I hope it helps!!
Happy Optimizing!!

Create overlapping two sweeps and join them.

The problem isn't the path, but the direction of the profile - it folds in on itself and that's a problem.

When the length of transition/path is less than 1xProfile Width (ie: a=b or a>b) you are less likely to be able to use a sweep.

Your best bet would be to work with 2 sweeps and joining them as suggested by Toan.

I got a shape with this part lost when using two separated sweep.

... I'll use extrusion to instead some of them until find a easier way.

Considering that you have used Pick Path, you can simply do the following:

• Switch to Wireframe to see the lines you have used to pick path
• Stretch or Align and lock as needed
• Use Join Geometry
