Limitări și complicații asupra Profilelor
- A vertex or point
- vertex or point may only be used as the first and/or last profile in the list of profiles.
- For example
- you can not Sweep from a circle to a point, to a ellipse.
- However you could Sweep from a point to a circle to an ellipse to another point.
- Open or closed geometry profiles can not be mixed in one single Sweep
- In one Sweep, all profiles (lines wires etc.) must be either open or closed.
- For example
- FreeCAD can not Sweep between one Part Circle and one default Part Line.
- Draft Workbench features
- Draft Workbench features can be directly used as a profile in FreeCAD 0.14 or later.
- For example the following Draft features can be used as profiles in a Part Sweep
- Draft Polygon.
- Draft Point, Line, wire,
- Draft B-spline, Bezier Curve
- Draft Circle, Ellipse, Rectangle
- PartDesign Sketches
- The profile may be created with a sketch. However only a valid sketch will be shown in the list to be available for selection.
- The sketch must contain only one open or closed wire or line (can be multiple lines, if those lines are all connected as they are then a single wire)
- Part Workbench
- the profile can be a valid Part geometric primitive which can be created with the Part CreatePrimitives tool
- For example the following Part geometric primitives can be a valid profile
- Point (Vertex), Line (Edge)
- Helix, Spiral
- Circle, Ellipse
- Regular Polygon
- Plane (Face)
