Curves SketchOnSurface

Description
This tool maps a sketch onto a face. The sketch must be actually attached to a face (see Sketch.Support). The mode of the sketch has no effect on the result.



Usage

 * 1) Switch to the [[Image:Curves_workbench_icon.svg|24px]] Curves workbench (you may need to install it via the [[Image:AddonManager.svg|24px]] Addon Manager
 * 2) There are 2 methods to use the SketchOnSurface tool:
 * 3) ; You already have a sketch that you want to map on a face:
 * 4) Attach the sketch to the target face.
 * 5) Edit the sketch and add a Construction (blue) rectangle around the geometries.
 * 6) * This rectangle will be the parametric bounds of the face.
 * 7) Exit edit mode.
 * 8) Select the sketch and activate SketchOnSurface by either:
 * 9) Pressing on the [[Image:Curves_SketchOnSurface.svg|24px]] button
 * 10) Using the  entry in the Curves menu
 * 11) ; You have no sketch to map yet:
 * 12) Select the target face in the 3D view
 * 13) Activate SketchOnSurface by either:
 * 14) Pressing on the [[Image:Curves_SketchOnSurface.svg|24px]] button
 * 15) Using the  entry in the Curves menu
 * A default sketch will be created and attached to this face.
 * A SketchOnSurface object will be created upon this sketch.
 * 1) Edit the sketch and add geometries inside the blue construction bounds.

Options

 * Fill Extrusion: When the Thickness value is not null, this will generate lofting faces (the blue faces in the above screenshot).
 * Fill Faces: This will fill all closed wires of the mapped shapes into faces (the red faces in the above screenshot).
 * Offset: This will offset the mapped shapes above or behind the target face.
 * Thickness: If not null, this will create a second set of shapes, that will be offset by the given value from the first ones.
