Tanım

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.

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.
