Will Fusion 360 add "Minimize thermal distortion" similar to SheetCAM?

SheetCAM has a setting when creating a toolpath for plasma that optimizes the 2d contour order for the least thermal distortion cased by cutting. Here is a description from the SheetCAM manual.

“Minimise thermal distortion
This option tries to avoid cutting outlines that are close to other recently cut outlines.
This helps to spread the heat over the sheet and minimize distortion. Increasing
‘Preferred distance between cuts’ controls the minimum distance between adjacent cuts.
Increasing this value spreads the heat more evenly but increases overall cut time
because of the extra rapid moves between cuts.”

Is there anything on the roadmap for Fusion 360 to adopt this feature?

It is a little more work, selecting geometry, but how about using the "Preserve Order" option under the Passes tab.

@jhackney1972 I had considered using "preserve order" while taking these steps/rules into account a guideline while picking the order but I was hoping for something more automatic.

 

    • .
  1. Divide the sheet into sections.
    • Divide the sheet into smaller sections, such as quadrants, to optimize the cutting order.
    • For example, you might cut the rectangles in one quadrant before moving on to the next quadrant.
  1. Start with the shapes closest to the edge.
    • Cut the rectangles closest to the edge of the sheet first to minimize the amount of heat that is absorbed by the surrounding material.
  1. Cut the rectangles with the largest area first.
    • Cut the rectangles with the largest area first to minimize the amount of time that each cut is in contact with the material.
  1. Cut rectangles with similar dimensions and spacing together.
    • Group rectangles with similar dimensions and spacing together to minimize the number of tool changes and reduce the amount of heat that is absorbed by the surrounding material.
  1. Minimize the number of pierces.
    • Use a strategy that minimizes the number of pierces required to cut all of the rectangles, such as a common line cutting strategy or a bridge strategy.
    • This will help to minimize the amount of heat that is absorbed by the surrounding material and reduce the potential for thermal distortion.

This feature would be very useful. The preserve order option works, but it's tedious and wastes time, especially if you're doing large quantities.
