Highlighted surfaces may be self-intersecting. Try modifying shape or Unwelding adjacent edges.

Hello,

This is in reference to the Fusion 360 Live - Organic Meshes in Fusion 360 excellent tutorial.

Using Fusion 360 version 2.x and not turning off the Parametric History, I was able to replicate all the steps until I got to the "self-intersecting" surfaces (welding) error and I could not find a way to use the "Boundary Fill" option without turning off the History. Is there another way with version 2.x to keep the History and use the "Boundary Fill" trick to convert the Pipe Form to a solid body?

Cheers!

Nikos
