Sketch-Loops.
Key Terminology
Sketch-Loop: the derived name of a closed chain of sketch-elements.
Merged-Points: two Points are merged to become one Point.
Objectives:
This topic shows a video of example sketch-loops in the Part-Editor.
•Sketch-elements are added, end-to-end, to form a single, continuous loop - see exceptions below.
•The Points¥ at each end of each adjacent sketch-element are merged.
•You do not need to add Constraints to any of the sketch-elements in a sketch-loop.
A sketch-loop is not an element. It is a derived element name.
We can add a Profile only to a sketch-loop, We can also add a Hole only to a sketch-loop.
¥ start-Point or end-Point of each sketch-element.
EXCEPTIONS - these are NOT Sketch-Loops:
•three(3) or more(3+) Points cannot be merged to one Point – this is a Branch Point
•sketch-elements cannot cross over each other - this is a Figure-of-Eight
•sketch-elements cannot touch each other - this has Zero-Thickness
