Additive Pipe creates a solid in the active Body by sweeping one or more sketches (also referred to as cross-sections) along an open or closed path. If the Body already contains features, the additive pipe will be merged to them.
On the left: cross-sections (A) and (B) to be swept along path (C); resulting Additive pipe on the right.
How to use
- Press the button.
- In the Select feature dialog, select a sketch to be used as first cross-section and click
- Alternatively, a single sketch can be selected prior to pressing the Additive pipe button.
- In the Pipe parameters under Profile, press the button.
- Select the sketch to be used as path in the 3D view:
- Alternatively, edges of the body can be selected by pressing and selecting edges in the 3D view.
- To use more than one cross-section, under Section transformation set the Transform mode to Multisection; press then select a sketch in the 3D view. Repeat for each additional cross-section.
- Set options if needed and click .
- Select Constant to use a single profile
- Select Multisection to use multiple profiles
- Orientation set by first profile and constant throughout
- Create minimum possible twisting of profile. For more info, see Frenet-Serret Formulas
- Specify secondary path to guide pipe
- Specify binormal vector in X, Y and Z
- 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.
- 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.
