Описание
Субтрактивный трубный профиль создает субтрактивное твердое тело в активном теле, перемещая один или несколько эскизов (также называемых поперечными сечениями) по открытому или замкнутому контуру. После чего созанная форма вычитается из существующего твердого тела. Субтрактивный трубный профиль часто применяется совместно с инструментами: спираль и связующая форма для создания резьбы; подробности см. в руководстве по созданию резьбы.

Применение

 * 1) Press the  button.
 * 2) In the Select feature dialog, select a sketch to be used as first cross-section and click.
 * 3) * Alternatively, a sketch or a face of a 3D object can be selected prior to pressing the Subtractive pipe button.
 * 4) In the Pipe parameters under Profile, press the  button.
 * 5) Select the sketch to be used as path in the 3D view:
 * 6) * Alternatively, edges of the body can be selected by pressing and selecting edges in the 3D view.
 * 7) 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.
 * 8) Set options if needed and click.

Section Transformation: Section Orientation: Corner Transition
 * Select Constant to use a single profile
 * Select Multisection to use multiple profiles
 * Standard
 * This keeps the cross section shape perpendicular to the path. This is the default setting.
 * Fixed
 * Orientation set by first profile and constant throughout. This deactivates the alignment to the path normal vector. That means that the cross-section shape will not rotate with the path. Sweep along a circle to see the effect.
 * Frenet
 * Create minimum possible twisting of profile. For more info, see Frenet-Serret Formulas
 * Auxiliary
 * Specify secondary path to guide pipe.
 * For each point along the sweep path, there will be a corresponding point  on the auxiliary path.
 * As the profile is swept, it will be transformed such that the line is the normal of the sweep path.
 * If is set, then the  points are scaled proportionally along the sweep path, regardless of is length.
 * Binormal
 * Specify binormal vector in X, Y and Z
 * Transformed
 * Right
 * Rounded

Свойства

 * : name given to the operation, this name can be changed at convenience.
 * : true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
 * : lists the sections used.
 * : true or false (default). True extends the path to include tangent edges.
 * : true or false (default). True extends the auxiliary path to include tangent edges.
 * : true or false (default). True calculates normal between equidistant points on both spines.
 * : profile mode. See Options.
 * : binormal vector for corresponding orientation mode.
 * : transition mode. Options are Transformed, Right Corner or Round Corner.
 * : Constant uses a single cross-section. Multisection uses two or more cross-sections. Linear, S-shape and Interpolation are currently not functional.
