Surface CurveOnMesh/de

Beschreibung
erstellt angenäherte Spline-Abschnitte auf der Oberfläche eines ausgewählten Netzes.

Ist das Objekt kein Netzsondern eine parametrische Form oder Fläche, muss es als erstes mit in ein Netz konvertiert werden.

Diese auf der Oberfläche des Netzes erstellten Kanten können später genuzt werden, um die Oberfläche parametrisch nachzubauen mit Werkzeugen wie und.





Anwendung

 * 1) Make sure you have a 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) 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 . Depending on how smooth the original mesh is, one spline or multiple splines will be created in the tree view.
 * 6) Repeat the sequence  → Pick →, to add more approximated splines.
 * 7) The new spline will be created, and will appear in the tree view, immediately after choosing ; the task panel will remain active.
 * 8) Press  to close the task panel, and terminate the command completely.

After pressing, the context menu (right-click) in the 3D view shows various 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.
 * : it will erase the tentative points that have been picked on the mesh, and will allow you to pick new ones.
 * : it will erase the tentative points that have been picked, and will stop the picking operation. Press again to pick points once more.

Optionen
section:
 * : it defaults to ; it indicates the minimum distance between one point and another when picking with the pointer.
 * : it defaults to ; it indicates the angular deviation from one point in the mesh to another point necessary to create a new spline instead of extending the previous spline.

, if it is, it will create spline objects, otherwise, it will create simple straight line objects (polyline).
 * : it defaults to . It is a parameter that takes into account the imperfections of the mesh; the smaller this number the more precise it will consider the mesh, particularly if it is a very fine mesh.
 * : it defaults to . It determines the continuity of the spline; it can be (touching),  (tangent),  (curvature), and  (acceleration curvature).
 * : it defaults to . It determines the maximum degree of the spline to approximate the surface; it can be a value from to.

Eigenschaften
If is unchecked, the Curve on mesh tool creates a basic Part Feature.

If is checked, the Curve on mesh tool creates a  ( class) which is derived from the basic Part Feature ( class), therefore it shares all the latter's properties.

In addition to the properties described in Part Feature, the Part Spline has the following properties in the property editor.

Ansicht

 * : it defaults to ; if set to, it will show an overlay with the control points of the surface.
