Macro Solid Sweep/de

Beschreibung
Dieses Makro erstellt einen Körper, indem ein 2D-Profil entlang einer zuvor in der 3D-Ansicht ausgewählten Trajektorie gefegt wird. Die 2D-Elemente können mit den normalen Werkzeugen in FreeCADs GUI erstellt werden.

It should be noted that the resulting solid will not be parametric. If you decide to change your profile or trajectory, you'll need to run the macro again.



How to use

 * Create two 2D elements, one for the section and one for the trajectory, of the types listed below.
 * Select, either in the Project tree or in the 3D view, first the trajectory, then the profile. The order is important!
 * Open the Macro manager, select the macro and click "Execute".
 * A Sweep object will be created in the Project tree.

Supported 2D elements

 * Wires
 * [[Image:Sketcher_NewSketch.png|32px]] Sketches
 * [[Image:Draft_BSpline.png]] Draft BSpline
 * 2D primitives from the Part → [[Image:Part_CreatePrimitives.png|32px]] Create Primitives ... menu (circle, helix)

Tips

 * The section has to be a closed profile or the result will not be a solid.
 * The section does not need to be located on the trajectory, but it's preferable that it be normal (perpendicular) to the trajectory.
 * The trajectory can either be an open or closed profile (circle, or line and arc segments) but all elements need to be tangent or the resulting shape will be unexpected. For example, a trajectory with straight corners like a rectangle will not produce a solid.
 * If the solid gets twisted, edit the macro to change the isFrenet value to 0 (zero) and try again.
 * Setting the makeSolid variable to 0 (zero) in the macro will produce a set of surfaces with open ends.

Two examples of uses can be found in this forum topic, along with download links to the FCStd files. Using a helix as trajectory, a solid sweep can be used to create a bolt thread.
