Entry / exit
These properties apply to both entry and exit.
Enter / exit at midpoint
On a closed path, this moves the entry / exit point to the midpoint of the path’s first segment.
Closed loop overlap
On a closed path, this extends the start and end of the path to cause an overlap. Only positive values are permitted.
Use entry parameters for exit
Uses entry values as the exit parameters. The Exit option must also be enabled to use this option.
Entry and exit parameters
Type
Defines entry or exit geometry.
Perpendicular line
Entry or exit will be a line perpendicular to the base toolpath at the intersection point of the entry / exit and toolpath.
Tangent line
Entry or exit will be a line tangent to the base toolpath at the intersection point of the entry / exit and toolpath. This is useful for entry or exit on a convex curved toolpath or where the entry or exit should be aligned with the toolpath.
Arc
Entry or exit will be an arc motion, tangent to the base toolpath at the intersection point of the entry / exit and toolpath. Use Arc radius and Arc sweep angle to control size of the arc.
Line and arc
Arc entry or exit with linear extension added.
Side
Entry and exit motions can be placed on the right or left side of a path. You can use this setting to correct situations where entry or exit motions are placed on the wrong side of a path.
Height / ramp
Create an incline on an entry or exit motion. Ramp height is the offset distance from the original start point of the entry or exit, along the approach vector.
Ramp height can also be used with Arc entry or exit paths.
This option is not recommended for plasma cutting.
Additional angle
Only available for linear entry / exit types (Perpendicular or Tangent). This adjusts the entry or exit path by a specified angle.
Arc radius
For Arc entry or exit paths, this is the radius of the arc. Use this to control the size of the entry or exit.
Arc sweep angle
For arc entry or exit paths, this is the angular distance the arc sweeps from the connecting point on the tool path.
Line length
Used with linear entry or exit, defines length in mm of entry or exit motion. Negative values are not permitted.
Extend / shorten path
A positive value will extend the base toolpath by adding a line tangent to the path, at the intersection of the entry / exit. The effect would be to move the entry or exit past the intersection point, creating an overlap.
A negative value will move the entry / exit back from the intersection point, leaving undertravel or a gap in the base toolpath.
Note that on curved toolpaths, the extension follows a tangent line, it does not follow contour of the toolpath.
Normalize direction
When enabled, the vector of approach will be perpendicular to the healed surface geometry, at the start of the entry. This will ensure that the pierce occurs with the torch perpendicular to the workpiece. After piercing, the vector gradually transitions to the cut path vector, as defined with Fanning distance.
When cleared, the vector of approach will be parallel to the cut path vector.
This option is available for plasma cutting only.
Fanning distance
When the Normalize direction option is enabled, Fanning distance controls the distance of the transition from the initial pierce vector to the cut path vector.
(image)
Set this to Automatic to transition gradually along the entire length of the entry or exit.
This option is available for plasma cutting only.
Use the Apply button as you edit leads to see changes.
Notes:
Mention the setting in Parameters for Projection to control how the healed surface is used for interiors.
Disable
Automatic Runs through three below and picks
Stock - Separate geometry has to be imported and labeled. This is workpiece geometry body that is
Untrim - Projecting onto healed surface; surface that has been trimmed will be healed. Works only with closed interior profiles ( ? )
Extension - extends current geometry out, as with exterior profiles

Does RM distinguish between interior and exterior profiles for leads?
