Description
Subtractive Pipe creates a subtractive solid in the active Body by sweeping one or more sketches (also referred to as cross-sections) along an open or closed path. Its shape is then subtracted from the existing solid. SubtractivePipe is often used in connection with Part Helix and PartDesign ShapeBinder to create a thread; see the Thread for Screw Tutorial for details.
Usage
- Press the Subtractive pipe button.
- In the Select feature dialog, select a sketch to be used as first cross-section and click OK.
- Alternatively, a single sketch can be selected prior to pressing the Subtractive pipe button.
- In the Pipe parameters under Profile, press the Object button.
- Select the sketch to be used as path in the 3D view:
- Alternatively, edges of the body can be selected by pressing Add Edge and selecting edges in the 3D view.
- To use more than one cross-section, under Section transformation set the Transform mode to Multisection; press Add Section then select a sketch in the 3D view. Repeat for each additional cross-section.
- Set options if needed and click OK.
Options
Properties
- DataLabel: name given to the operation, this name can be changed at convenience.
- DataRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
- DataSections: lists the sections used.
- DataSpine Tangent: true or false (default). True extends the path to include tangent edges.
- DataAuxiliary Spine Tangent: true or false (default). True extends the auxiliary path to include tangent edges.
- DataAuxiliary Curvelinear: true or false (default). True calculates normal between equidistant points on both spines.
- DataMode: profile mode. See Options.
- DataBinormal: binormal vector for corresponding orientation mode.
- DataTransition: transition mode. Options are Transformed, Right Corner or Round Corner.
- DataTransformation: Constant uses a single cross-section. Multisection uses two or more cross-sections. Linear, S-shape and Interpolation are currently not functional.
Limitations
- Sketches used for cross-sections must form closed profiles.
- It is not possible to use a vertex as cross-section.
- A cross-section cannot lie on the same plane as the one immediately preceding it.
- To better control the shape of the pipe, it is recommended that all the cross-sections have the same number of segments. For example, for a pipe between a rectangle and a circle, the circle may be broken down into 4 connected arcs.
