Sketch-Loops.

Key Terminology

Sketch-Loop: the derived name for a closed chain of sketch-elements.

Merged-Points: two Points* that are merged into one Point.

* start-Point or end-Point of each sketch-element.

Objectives:

This topic has a video of example sketch-loops in the Part-Editor.

•Add sketch-elements, end-to-end, to form a single, continuous loop - see exceptions below.

•Add Constraints to the sketch-elements. Constraints are not required, but it is good practice.

We can add a Profile to a sketch-loop. We can also add a Hole to a sketch-loop.

EXCEPTIONS

With sketch-loop:

•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 (other than their merged-Points) - this is Zero-Thickness
