Click the edge, edge chain, vertex, or note text you want to project into the
sketch plane.Standard edge selection methods apply, so you can
double-click, Ctrl+click, and Shift+click to create or modify your
selection.
You can also click and drag to draw a selection box
enclosing the objects you want to project, including silhouette
edges.
The edge, vertex, or text appears as a sketched line to show
that it is now a line or point in the sketch plane.
Duplicate edges
(that appear on top of each other) in the sketch are consolidated when you
return to 3D mode.
Tip If you have difficulty seeing a projected line, check that
Fade Scene Under Grid is selected on the Display
tab.
Project to Sketch in the Sketch group on the Design
tab.
Mouse over your design to highlight the objects available for projection.
