Description

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

Usage

Switch to the Curves workbench (you may need to install it via the Addon Manager
There are 2 ways to use SketchOnSurface :

  • You already have a sketch that you want to map on a face:

Attach the sketch to the target face.
Edit the sketch and add a Construction (blue) rectangle around the geometries.
This rectangle will be the parametric bounds of the face. Exit edit mode.
Select the sketch and activate SketchOnSurface.

  • You have no sketch to map yet:

Select the target face in the 3D view and activate SketchOnSurface.
A default sketch will be created and attached to this face.
A SketchOnSurface object will be created upon this sketch.
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.
