Step 4.1: Sketch-Loops and Merged-Points
Contents
Sketch-Loops.
This topic describes how to use the Part-Editor to obtain a sketch-loop, with Merged-Points.
A Sketch-Loop is a closed chain of sketch-elements. The sketch-elements are added end to end , all Points are Merged-Points*
A sketch-loop is not an element. It is a derived name.
We can add a Profile to a sketch-loop, and a Hole through a Profile.
A Point at the end of one sketch-element must be merged with a Point at the end of a different sketch-element: we say the Points are Merged-Points.
These are NOT Sketch-Loops
| • | When you merge three or more Points as one Point – this is a Branch Point |
| • | When the sketch-elements cross each other - this is a Figure-of-Eight |
| • | When the sketch-elements touch each other to give 'zero' thickness between two sketch-elements. |
Example Sketch-Loops
