Layout Sketches

You can sketch on a plane when you want to draw curves but have no immediate need to generate 3D objects. If you want to create a region that can be pulled into 3D right away, create a sketch instead.

You can think of a layout as a pencil drawing made on your design. If you try to pull layout lines to 3D, they do not behave the same way that sketched lines do. Closed lines are not converted to regions, so if you pull a layout line, it creates a surface, not a solid. When you are ready to use your layout to create geometry, project the layout lines to a sketch. Projecting a layout line to a sketch is like inking the line.

Layouts always appear on planes in the Structure tree.

You can use layers when working with layouts to help organize your design. For example, you can color individual lines on each layout, show or hide the lines, or put the bounding planes on a separate layer and turn that layer's visibility off to declutter your design. (When you import files, they will initially appear in one color.)
