Highspeed Spiral, outside in

[Geardoman]

Hi!

 

I wounder if anyone has a solution on my problem with the surface highspeed spiral toolpath.

What I want to do is a spiral with the zigzag option that spiral outside in instead for inside out. I need to use a containment, so I will not be able to use blend.

I attach a picture that shows that I'm looking for but the path on the picture start inside and working to the outside..

Back plot the tool path. Save the Geometry and then use the chain created to run a 3D Contour.

 

Might look at the HST Toolpaths for finishing to see if they will allow you what you are after.

Keep in mind you can run the Blend Toolpath with a closed chain around the periphery of your surface, and use a "chained point" for the second chain in the middle of your surface. That will give you the outside -> in motion if you chain the periphery first.
