Introduction
These commands allow to define overlengths for the input and the output of the tool in the material.
Start and Final Overlengths
Open ProfileStart Overlength (1)The first element of the profile is extended by the defined value. If the value is negative, the profile is shortened. For an open profile, the overlength follows the same nature as the first element:
Tangency with the profile is always maintained. Final Overlength (2)The last element of the profile is extended by the defined value. If the value is negative, the profile is shortened. For an open profile, the overlength follows the same nature as the last element:
Tangency with the profile is always maintained. |  |
Closed ProfileStart Overlength (1)The start overlength is generated tangent to the last element of the profile. For example, if the profile starts on an arc and ends on a segment, the start overlength will be linear. Final Overlength (2)The final overlength is generated tangent to the first element of the profile. For example, if the profile starts on an arc and ends on a segment, the final overlength will be circular. |  |
Linear Overlengths
Cycle: Contouring
Unlike the Start and Final overlengths, which extend or shorten the profile while maintaining tangency with its elements, the Linear overlength parameter extends or shortens the toolpath strictly in a linear direction at the start or end of the profile. This parameter can be used in combination with Start and Final overlengths. | ▶️ Watch a video about Linear Overlength.  |
