Notes...The arc option only works with profile files that are "flipped" parallel to the X axis. Information on the original Extruder and all this flipping business can be found in the March 2006 Bill's Corner article. If you haven't it already, download the original extruder and play with it to get a sense of how it works. You can test the new arc and ellipse extrusion feature with the "Ellipse test file.sbp" file that's in this download. There's also a file named "dish.sbp" that you can use to see how the Extruder could be used to create a bowl shape. Set the X and Y radius to 0.0 and the X and Y center to 0.0, and the rotation angles from 0 to 360 to try it out.

Project Type...Update
Additional equipment/software required...Part Wizard required to create profile file
Special instructions...For the radius of the arc to be the correct size the extruder needs to know where the original corner of the profile is, not the offset toolpathed corner. For this reason when you're doing the profile file for an arced extrusion you need to have your original profile with it's "right-hand" corner at X=0 before you toolpath it like this drawing
Known Issues...11/10/07 The Extruder currently doesn't work with Part Works and other Vectric software, because they don't allow Outside profile toolpaths on an open vector. A fix is being worked on, but the only current workaround is to generate the offset in another program like a CAD program and then generate the file in Part Works as a toolpath along the vector.
