I have a loft using 14 spline sketch sections each on its own plane. Each spline point is driven by an external database along with the spacing of the planes. Sections 3 and 4 are not working well and need to be replaced. I cannot change the values from the database (proprietary), but I need to tweak the loft. The surface has other features built on it, so I cannot delete the surface and recreate it.
I want to create a couple new spline sketches on planes 3 and 4 with relationships to the original sketch.
Next, I want to have the same loft use my new sketches in place of the original sketchs - I won't be deleting the original sketches.
Is it possible to create new sketch sections then replace them in the existing loft?
If not, is there another way to fix it?
