Guiding Curves
Overview
Capabilities
• Guiding Curves is a surface milling operation where
the pattern is driven by one or two sets of curves
(Guides)
• “Morphing” – the pattern is evenly interpolated
between the two guides
• “Constant Offset” - offsets the guide with
Constant stepovers
• Pattern is highly controlled by the user. He can drive
the pattern to follow his intent
Customer Benefits
• Smooth toolpath
• Better surface quality

Merge Path By Contour Count / Concatenation
Why
• Attempting to satisfy complex specific rules in a native
operation highly mess the UX
• Competition has merging and editing capabilities uses as part
of the base workflow
What
Merge 2 or more operations
Merging rule – by Contours count
Lag to satisfy shift of the count for the first set
Merge into one “level” (?)
