Surface CurveOnMesh

Description
creates approximated spline segments on top of a selected mesh.

If the object is not a Mesh, but a parametric Shape or surface, it must be converted first to a mesh using.

These edges created on top of the mesh may be further used to re-create the surface in a parametric way by using tools such as and.



Usage

 * 1) Make sure you have mesh object. This can be created by the Workbench_Mesh.svg Mesh Workbench, or by importing a mesh file type, like STL, OBJ, or DAE. If a solid object or solid file type (STEP) is used, it can be converted to a mesh using.
 * 2) Select the mesh, then press.
 * 3) Press.
 * 4) Using the mouse pointer, pick points on the surface of the mesh in the 3D view; pick as many points as necessary to draw a smooth preview line.
 * 5) When enough points have been added, right click on the 3D view to open the context menu, and select.
 * 6) Depending on how smooth the points were added, one object or multiple objects will be created in the tree view.
 * 7) Repeat the sequence  → Pick →, to add more approximated splines.
 * 8) The new spline will be created, and will appear in the tree view, immediately after using ; the task panel will remain active.
 * 9) Press  to close the task panel, and terminate the command completely.

After pressing, the context menu (right-click) in the 3D view shows other options beside.
 * : if at least three points have been picked, this option will be available to join the last point to the first point with a line. Then can be used to produced a closed spline.
 * : it will erase the tentative points that have been set up to this moment on the mesh, and will allow you to pick new ones.
 * : it will erase the tentative points that have been set, and will stop the picking operation. To pick points once more, must be pressed again.
