Úvod

Tento nástroj otáčí náčrtem nebo 2D objektem podle zadané osy a odebírá materiál z podkladu. Například, obrázek ukazuje drážku vyříznutou na hřídeli.

The Groove tool revolves a selected sketch or profile about a given axis, cutting out material from the support .

Above: sketch (A) is revolved around axis (B); resulting groove on solid (C) is shown right.

Usage

  1. Select a single sketch or one or more faces from the Body.
  2. Press the Groove button.
  3. Set the Groove parameters, see Options below.
  4. Press the OK button.

Volby

Při vytváření drážky, dialogové okno 'parametry drážky' nabízí několik parametrů, které specifikují jak by se náčrt měl otáčet. Mají stejný význam jako u vlastnosti otáčení.

When creating a groove, or after double-clicking an existing groove in the Tree view, the Groove parameters task panel is shown. It offers the following settings:

Type

introduced in version 0.22

Type offers five different ways of specifying the angle of the groove:

Dimension

Enter a numeric value for the Angle of the groove. With the option Symmetric to plane the groove will extend half the given angle to either side of the sketch or face.

Through all

The groove will extend up to the last face of the support it encounters in its direction. With the option Symmetric to plane the groove will cut through all material in both directions.

To first

The groove will extend up to the first face of the support it encounters in its direction.

Up to face

The groove will extend up to a face. Press the Face button and select a face or a datum plane from the Body.

Two dimensions

This allows to enter a second angle in which the groove should extend in the opposite direction. The directions can be switched by checking the Reversed option.

Axis

Specifies the axis of the groove:

  • Vertical sketch axis: selects the vertical sketch axis.
  • Horizontal sketch axis: selects the horizontal sketch axis.
  • Construction line: selects a construction line from the sketch used by the groove. The dropdown list will contain an entry for each construction line. The first construction line will be labelled Construction line 1.
  • Base (X/Y/Z) axis: selects the X, Y or Z axis of the Body's origin.
  • Select reference...: allows the selection of a straight edge or a datum line from the Body.

Note that when changing the axis, the Reversed option may be (un)checked automatically.

Angle

Defines the angle of the groove. This option is only available if Type is Dimension or Two dimensions. Angles larger than 360° are not possible. Nor are negative values, use the Reversed option instead.

Symmetric to plane

Check this option to extend the groove half the given angle to either side of the sketch or face, if Type is Dimension, or Through all if that is the Type.

Reversed

Reverses the direction of the groove.

2nd angle

introduced in version 0.22

Defines the angle of the groove in the opposite direction. This option is only available if Type is Two dimensions and Angle is smaller than 360°.
