Linear Dimensioning, Free (3-D)

3-D Dimensioning + Text > Direct

You use this function to create linear dimensions that lie parallel to the identified objects – irrespective of the active coordinate system.

Linear dimension

Independent dimensions with only one dimension geometry and one dimension figure.

Half-section dimension (click )

Dimensions in which the second dimension point is created by mirroring the first dimension point on a symmetry axis. Half-section dimensions are generally used to represent lengths of symmetrical parts. The representation is made in half-section, i.e. with a projection line and shortened dimension line.

Chain dimension

Dimension group in which two consecutive sub-dimensions have a common dimension point.

Parallel dimension

Dimension group in which all sub-dimensions have the same start point, and the dimension lines of the sub-dimensions a fixed distance from one another.

Running dimension

Chain dimensions in which all sub-dimensions refer to the same start point (the reference point). The dimension figures are automatically placed at the end of each dimension unit, perpendicular to the dimension line. The reference point is identified by the dimension figure 0.

Running chain dimension (click )

A combination of running dimension and chain dimension.

Heights above datum

Special reference dimensions in steel engineering and mechanical engineering.

Coordinate dimension(click )

Special reference dimensions in which the first identified point is interpreted as the reference point. Starting from this point, each absolute dimension between the reference point and the other dimension points is determined. The reference point is identified with the dimension figure 0.

You operate these functions in the same way as the Axially parallel linear dimensions functions:

Activate the part to which you want the dimensioning to be assigned.

Choose the desired dimensioning function.

Identify any two edges or points in the drawing. For example, the points do not necessarily need to be end points of an edge and can also belong to different parts.

Identify the edge to be dimensioned directly and use END (right mouse button) to end the identification.

Determine the position of the dimension. Use the right mouse button to activate the Dimensioning, Move context menu. This context menu enables you to determine the position of dimension line and dimension figure.

Determine the subsequent points in the dimensioning structure.
