Create Spiral
This feature creates spiral geometry which may then be used to generate spiral cuts. The geometry will be created at the coordinate specified in the dialog at a depth of zero.
X Coordinate
Horizontal coordinate of the origin.
Y Coordinate
Vertical coordinate of the origin.
Outer Radius
Radius of the outer edge of the spiral or the starting point.
Inner Radius
Radius of the inner edge of the spiral or the ending point.
Offset
Gap between revolutions of the spiral.
The Create Spiral Plug-in can also generate a Z-axis revolved spiral around X0Y0 when the Plug-in is activated with selected geometry. The geometry may be an arc, line, or spline and must be created in the XY plane. The system will generate a spiral with the profile of the selected geometry; it can then be machined with a Contouring process. Note that the geometry should not cross X0 (or the Y axis) as the shape will be revolved.
Cutting Direction
Direction of the spiral, either clockwise or counterclockwise.
StepOver
Length of the gap between revolutions of the spiral.
2D Offset
Additional distance at which the geometry will be generated. Both positive and negative values are allowed.
Full Circle at Start
A generated spiral will include a complete circle at its start point. The circle is flat and perpendicular to the depth axis. This creates a start loop on the spiral geometry.
Full Circle at End
A generated spiral will include a completed circle at its end point. The circle is flat and perpendicular to the depth axis. This creates a finish loop on the spiral geometry.
Progress Direction
Direction in which the spiral is created. Use Top Down or Bottom Up for geometry whose height (or Y values) changes. Top Down will generate the spiral beginning at the highest Y value while Bottom Up starts at the lowest Y value. Use Inside->Outside or Outside->Inside for flat geometry (such as a horizontal line). Inside->Outside will generate the spiral beginning at the lowest X value while Outside->Inside will start at the highest X value.
Lead In/Out Radius
Creates an arc of the specified radius value to function as a Lead In or Lead Out when machining the geometry.
