Need to get centre curve from dumb solid?

Hi there,

1. Extract your surfaces from the solid.
2. Create a parallel curve on the surface extracted above.
3. Create center points on the edges of the extract on either side.
4. Create two lines outward from the created points.
5. Create a connect curve using the "base curve" option selecting the parallel curve as the base curve and the lines as first and second curve.

The connect will be your center curve for the solid.
Hope this helps.

Another option.

Extract the face of the duct (cross section)
then extract an isoparam from the duct, and use it as a guide for the sweep.

thats assuming you have GSD module.
