+Some arcs are composed of multiple smaller arcs.

 ==== Engrave toolpath ====
 If traces come close together, the tool will lift, cutting a thinner trace. This allows to set a relatively deep trace over-all to accommodate flex in the PCB substrate.
-  * Select the area in between traces and push it down a small amount. The depth doesn't matter. This creates a pocket we can use to select the engrave toolpath.\\ {{:isel_icv4030:fusion_pcb_01.png?400|}}\\

   * Add an engrave toolpath strategy and select the traces. You don't need to select the holes yet, but **make sure to select a contour line around all the traces**. That way Fusion knows at which side of the lines the tool need to be placed. I tested 0.3mm depth, but 0,2mm or shallower should work better.\\ {{:isel_icv4030:fusion_pcb_02.png?400|}}\\ {{:isel_icv4030:fusion_pcb_03.png?400|}}\\ Here you can see the cut is made on the outside of the traces.

   * No need to ad these to the tool list in Fusion. Simulate them with a 1mm flat endmill.
   * Take the CAM profile "PCB-Drill" from CAM Templates > PCB. This plunges the drill straight down. As it does not helix, the hole is the same diameter as the drill.
