KOMPAS-3D v23

To begin building a vector, start by clicking Build Vector button . Once you click it, buttons for activating vector-building commands will appear in the title toolbar of the Parameter Toolbar.

In KOMPAS-3D it is possible to construct:

•Vector through two points,

•Vector by angle in the CS plane,

•Vector by CS axis,

•Vector by coordinates,

•Vector by two angles of spherical CS,

•Vector by edge or planar curve,

•Vector by cone axis or perpendicular to surface,

•Vector Perpendicular to Face at Specified Point,

•Basis Vector at Curve Point,

•Vector perpendicular to the screen surface.

After creating the vector, the system automatically returns to the command from which the vector building process was launched.

Vector through two points

A vector directed from one point object to another is constructed using the Vector through two points command.

After calling the command on the Parameter Toolbar, controls appear that allow you to set vector constructive parameters.

Step-by-step instructions

1.Pick first point object. The name of the selected point object is displayed in the field Starting point.

2.Pick the second point object. The name of the selected point object is displayed in the End point field.

Point features are specified in the graphics area or in the Design Tree. If necessary, you can build a point during the execution of the command. To do this, press the Build Point button to the right of the Start Point(End Point) field. Will start subprocess of plotting a point. After creating the point, the system will return to the vector building process.

In the graphics area displays a vector phantom, directed from the first point to the second.

3.If necessary, the direction of the vector can be reversed (from the end point to the starting point) by clicking the Change direction button.

4.To complete building the vector, click the Create object .

Vector by angle in the CS plane

The vector directed at an angle to the specified coordinate axis and lying in the SC plane is constructed by the Vector by angle in the SC plane command. After calling the command on the Parameter Toolbar, controls appear that allow you to set vector constructive parameters, and a vector phantom with default settings appears in the graphics area.

When constructing the vector plane is determined by the chosen axis:

•if the X axis is indicated, then the angle of the vector is counted in the XY plane,

•if the Y axis is indicated, then the angle of the vector is counted in the YZ plane,

•if the Z axis is indicated, then the angle of the vector is counted in the ZX plane.

Step-by-step instructions

1.Choose a coordinate system for constructing a vector from the list of SC. The list is available if there are several coordinate systems in the model. Otherwise, the vector is constructed in the absolute coordinate system of the model.
The starting point of the vector coincides with the beginning of the selected coordinate system.

2.Specify the axis of the coordinate system for reference angle vector. To do this, click the corresponding button in the Axis CS:

From axis X in plane XY,

Vector by two angles of spherical CS

The vector, the direction of which in the chosen coordinate system is given by azimuth and spherical angles, is constructed by the Vector by two angles in the spherical coordinate system command.

The direction of the vector is determined by two angles A and B. Angle A corresponds to the azimuth angle α spherical coordinate system, and the angle C – the zenith angle β. The origin of the spherical coordinate system coincides with the origin of the coordinate system of the vector. Azimuth angle α is counted in the XY plane of the vector coordinate system from the X axis counterclockwise (see figure below). In the XY plane, the OC beam is conducted at an azimuthal angle to the X axis.

In the plane passing through the Z axis and the OC half-line, the OD half-line is drawn at a zenith angle to the Z axis. This half-line determines the direction of the vector to be constructed.

Basis Vector at Curve Point

To build a vector the direction of which is set by one of three basis vectors (t, n, and b) in a specified point of a curve are constructed using the Basis vector at a point of the curve command.

The curve can be a spatial curve, a sketch line, an edge, or a broken line segment.

The position of the point and the corresponding three triples of basis vectors is given by the displacement along the curve some distance from its vertex. This point is the starting point of the created vector.

Step-by-step instructions

Two phantoms will be created on the curve: a tangent vector and a starting vertex of the curve with an offset direction arrow (U). The tangent vector starts at the point where the curve is indicated.

2.Specify the position of the reference point of the basis vectors on the curve in one of the ways:

•Set the offset from the top of the curve by clicking the corresponding button in the group Move:

In % of curve length: enter offset in percentages in the field% of curve length.

By segment length: enter the offset in units of measurement of length in the field Length.

By the central angle of the arc: enter offset in angular measurement units in the field Angle. (The option is available if an arc of a circle or ellipse is selected as the curve).

You can change the reference direction of the point offset to the opposite (from the final vertex of the curve to the initial one) by clicking the Change Direction button to the right of the field where the offset value is set.

If necessary, you can change the position of the model without changing the position of the vector. To do this, disable the option. The vector is located in the center of the screen and is directed perpendicular to the screen plane.
