Description

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 Additive 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 Additive pipe button. In that case you will not get a "Select feature' dialog.
In the Pipe parameters under Path to sweep along, 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

Section Transformation:

Select Constant to use a single profile
Select Multisection to use multiple profiles

Section Orientation:

Standard
Fixed
- Orientation set by first profile and constant throughout
Frenet
- Create minimum possible twisting of profile. For more info, see Frenet-Serret Formulas
Auxiliary
- Specify secondary path to guide pipe
Binormal
- Specify binormal vector in X, Y and Z

Corner Transition

Transformed
Right
Rounded

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.
