How do I add a Sketch-Loop?

Add a sketch-path or sketch-loop

A Sketch-Loop is a series of sketch-elements that does not have breaks and the Points that join the sketch-elements are merged into one Point.

Add a sketch-loop to add to it a Profile/Extrusion (Solid) or a Motion-Path FB.

About Merge-Points and Coincident-Constraint

Each Line, Arc, Blend-Curve has a Point at its ends. We call these Points the start-Point and end-Point.

To join different sketch-elements, you can:

make their Start-Point/ end-Points coincident - see Constraints toolbar > Add Coincident

Add Coincident does not remove a Point.

- or -

merge their Start-Point/ end-Point - see Geometry toolbar > Merge-Points

Add Merge-Points does remove a Point

Why Merge-Points?

You can use a closed sketch-path (sketch-loop) for a Profile.

You can use an open or closed sketch-path for a Motion-Path FB.
