From FreeCAD Documentation
  1. Make sure you have at least two objects in your document; the "source" object that you wish to project, and the "target" object where the projection will be made.
  2. Click on Projection on surface to launch a task panel with various options.
  3. Click on Select projection surface, and then click on the "target" surface where the projection will be created.
  4. Then click on the specific button to choose the type of subelement that you want to add to your projection object.
    • Add face: select a source face.
    • Add wire: select a source edge. The tool will extract the entire wire to which the edge belongs. For example, by choosing a single edge of a polygon, it will project the entire polygon.
    • Add edge: select a source edge. The tool will only project the selected edge.
    • Once a button is depressed, pick a subelement in the 3D view. If you wish to deselect it, pick the same element again.
    • When you are satisfied with your selection, press the same Add... button to leave the selection mode.
  5. Then click on the specific radiobutton to choose the type of projection shape to create.
    • Show all: it will show all types of closed wires and edges on the target surface. If a "face" subelement was selected in the previous step, a preview of a solid object extruded from the projection will be shown, depending on the value of Extrude height.
    • Show faces: it will show a preview of a filled face on the target surface. This will only work if you selected a "face" subelement in the previous step; if you selected a closed "wire", only the edges (no face) will be created as projection; if you selected "edges", only those edges will be created as projection.
    • Show edges: it will show a preview of the edges on the target surface. This will work whether you added a "face", "wire", or "edge" subelement in the previous step; even if you added a filled "face", only the edges will be created as projection.
  6. Press the OK to complete the operation and produce the new projection object.
