Inventor 2019 3D Sketch Spline Path Smooth Sweep

ZaC-04 — Thu, 09 Aug 2018 17:07:15 GMT

Hi,

How do i make the 3D Sketch path the same as the image attached?

The Spline sits above the construction line. The Straight End line & Spline & Coil should be level until the coil starts to move up/down

What changes would i need to make?

Thanks

Your coil must transition from helix to flat. Back in a few...

Q. Do you want an abrupt change or a smooth change in the curve?

Smooth change .. thanks

See Attached.

It is a bit of trial and error - keep in mind realistic manufacturing tolerances.
