Pipe Construction

To generate a Pipe in the Main Menu select New Entity - > Generation - > Extrusion along a path

Firstly, to create an extruded Pipe shape, you can define the Base Object (vertex, edge, planar wire, face or shell), which will be extruded and the Path Object (edge or wire) along which the Base Object will be extruded.
It is possible to select in GUI several Base Objects to make several pipes (using Shift button).
In this mode the default pipe generation algorithm is used. The pipe is created so that the angle between the normal vector to the base shape and the tangent to the path wire remains constant at any point of the given path.
Select unpublished edges checkbox - if checked, allows to select an edge of any other shape as the path object.
Generate groups checkbox - if checked allows to create groups of sub-shapes. For more details on groups creation please refer to this description.
The Result of the operation will be a GEOM_Object (edge, face, shell, solid or compsolid).

TUI Command: geompy.MakePipe(baseShape, pathShape, IsGenerateGroups=False)
Arguments: Name + 1 shape (vertex, edge, planar wire, face or shell) serving as base object + 1 shape (edge or wire) for definition of the path + 1 boolean parameter (IsGenerateGroups).

Secondly, you can define the Base Object (edge, planar wire or face), which will be extruded, the Path Object (edge or wire) along which the Base Object will be extruded and the BiNormal Vector (edge or wire).

In contrast to the default mode, in this mode the pipe is generated to preserve the constant angle between the normal vector to the base shape and the BiNormal vector given as the third argument.
Select unpublished edges checkbox - if checked, allows to select an edge of any other shape as the path object.
Generate groups checkbox - if checked allows to create groups of sub-shapes. For more details on groups creation please refer to this description.
The Result of the operation will be a GEOM_Object (edge, face, shell, solid or compsolid).

TUI Command: geompy.MakePipeBiNormalAlongVector(baseShape, pathShape, binormalShape, IsGenerateGroups=False)
Arguments: Name + 1 shape (edge, planar wire or face) serving as base object + 1 shape (edge or wire) for definition of the path + 1 shape (edge or wire) to set a fixed BiNormal direction to perform the extrusion + 1 boolean parameter (IsGenerateGroups).

Example:

Extrusion of a face with BiNormal parameter

Thirdly, it is possible to additionally select profiles of the pipe object to be built. For this, you can define the following parameters:

• Base Object or a list of objects (edges, planar wires, faces or shells), which will be extruded;
• Locations - a vertex or a list of vertices that specify the locations of extruded Base Objects on the resulting Path Object. The number of Base Objects should be equal to the number of Locations.
• Path Object (edge or wire), along which the Base Object will be extruded.

Additional controls:

• If With contact is checked, the section is translated in contact with the spine.
• If With correction is checked, the section is rotated to be orthogonal to the spine tangent in the corresponding point.
• If Step-by-step generation is checked, the result is created step-by-step, i.e. it creates pipes between each pair of neighbor sections and fuses them into a single shape.

Note

If Step-by-step generation is checked, With contact and With correction controls are disabled as corrections of bases are not allowed in step-by-step mode.

Generate groups checkbox - if checked allows to create groups of sub-shapes. For more details on groups creation please refer to this description.
The Result of the operation will be a shell or a solid.

TUI Commands:

• geompy.MakePipeWithDifferentSections(baseShape, locations, pathShape, withContact, withCorrection, IsGenerateGroups=False)
  Arguments: Name + list of shapes (edges, planar wires, faces or shells) serving as base object + list of locations (vertices) on the path corresponding specified list of the shapes + 1 shape (edge or wire) for definition of the path + 3 Boolean parameters (withContact, withCorrection, IsGenerateGroups).
• geompy.MakePipeWithDifferentSectionsBySteps(baseShape, locations, pathShape, IsGenerateGroups=False)
  Arguments: Name + list of shapes (edges, planar wires, faces or shells) serving as base object + list of locations (vertices) on the path corresponding specified list of the shapes + 1 shape (edge or wire) for definition of the path + Boolean parameter.
