Notes About Rotational Scans

 * Rotational scans require much more time and processing than Planar scans. Factors affecting processing time include: Sample Interval, Step Over, tool diameter, and model size.  Again, rotational scans can take a long time.  Some might take 3, 5 or 10 minutes or longer.
 * For time purposes, it is better that you not recompute a rotational scan after every property change; rather, consider one of the following:
 * use the ' change all settings with ENTER key ' technique mentioned in Step 2 above, then the operation.
 * deactivate the operation with the toggle tool, make your changes to the operation's properties, then click the  icon again to re-activate the operation - which triggers a recompute internally.
 * The operation is still considered an experimental feature as of 2019-06-25. As such, it may contain a few bugs yet to be clearly identified.  Please report bugs and issues in the FreeCAD Path/CAM Forum.
 * The OCL Waterline algorithm does not support rotational scans.
 * The built in does NOT support 4th-axis simulation.  You will need to use a third party simulator to inspect or verify paths visually.  See the Resources section below for suggestions.
 * You will likely see red rotational lines around your model in the viewport. This is normal in FreeCAD for the time being.

Available Tool (Cutter) Shapes
This 3D Surface op currently uses OpenCamLib [OCL] to extract paths from the part base. As such, a tool setting translation is required between the FreeCAD tool controller and OCL in order to complete the scan with your chosen tool(cutter) shape.
