Linear Dimensioning, Parallel (3-D)

3-D Dimensioning + Text > Parallel

Use the functions in the functions groups Individual dimensions and Parallel to create individual linear dimensions and sets of linear dimensions the dimension lines of which run parallel to one of the axes of the coordinate system, or to a freely selectable reference axis.

Example: Chain dimension, axially parallel (left) and parallel dimension with chamfer as reference axis

• Functions for parallel linear dimensions
• Axially parallel linear dimensions
• Linear dimensions parallel to a reference axis

Functions for parallel linear dimensions

The following functions are available:

3-D Dimensioning + Text > Individual dimensions
	Variable dimension Creates a linear dimension parallel to an axis of the current coordinate system (independent dimension with only one dimension geometry and one dimension figure). The dimension is assigned to the active part.
	Linear dimension, axially parallel Creates a linear dimension parallel to a selected axis
	Linear dimension, with reference axis Creates a linear dimension parallel to a selected axis.
	Half-section dimension, axially parallel Creates a half-section dimension, i.e. a dimension whose second dimension point is created by the mirroring of the first dimension point on a symmetry axis. Half-section dimensions are normally used to show the lengths of symmetrical parts. The parts are represented as half-sections, i.e. with a projection line and a shortened dimension line. Example

	Create new chain dimension Creates a set of dimensions in which two consecutive sub-dimensions have a common dimension point. The dimensions are axially parallel. Example
	Create new chain dimension, with reference axis Creates a chain dimension with dimension lines parallel to a selected axis.
	Create new parallel dimension Creates a set of dimensions with all sub-dimensions referring to the same start point and the dimension lines of the sub-dimensions having a fixed distance to each other. The dimensions are axially parallel. Example
	Create new parallel dimension, with reference axis Here the dimension runs parallel to a freely definable axis.
	Create new running dimension Creates a chain dimension with all sub-dimensions referring to the same start point (the reference point). The dimension figures will be automatically placed in vertical direction to the dimension line at the end of each sub-dimension. The reference point is indicated by the dimension figure "0". The dimensions are axially parallel. Example
	Create new running chain dimension Creates a combination of reference dimension and chain dimension. The dimensions are axially parallel. Example
	Create new running dimension, with reference axis Creates a running dimension the dimension lines of which are parallel to a reference axis.
	Create new running chain dimension, with reference axis Creates a combination of reference dimension and chain dimension. The dimensions are axially parallel to a reference axis.
	Create new height above datum Special axially parallel running dimension used in Civil Engineering and Steel Engineering. Example
	Create new height above datum, parallel to z-axis Height above datum, referring to the XY-plane of the coordinate system Example Please note: The dimensions created with this function are individual dimensions. An allowance can be specified for individual or all dimensions of this type for this function. To do this, choose the Structure start value. You will find this function in the context menu (right-click dimension figure) or at 3-D Dimensioning + Text > Tools > Extras >....
	Create new coordinate dimension Special axially parallel reference dimension, in which the first identified point will be interpreted as reference point. From this point, the absolute dimensions between the reference point and the other dimension points will be detected. The reference point will be indicated by the dimension figure "0". Example
	Create new height above datum, with reference axis Special running dimension used in Civil Engineering and Steel Engineering, with dimension lines running parallel to a defined axis.
	Create new coordinate dimension, with reference axis Coordinate dimension, with dimension lines running parallel to a defined reference axis.

Please note:

• The current dimension parameter settings will be considered for new dimensions. Please note that (depending on the settings on the System tab) the dimensions will be projected onto the active processing plane.
• Please also read the information given in the topics Dimensioning - Procedure and Dimensioning - Element Type Selection.

Axially parallel linear dimensions

1. Activate the part to which you want the dimensioning to be assigned.
2. Choose the desired dimensioning function.
3. Identify the geometry element to be dimensioned. These can be pints, edges or surfaces. For example, the points do not necessarily need to be end points of an edge and can also belong to different parts.

or

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

4. 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.
5. Determine the next points in the dimensioning structure or end the function by pressing the middle mouse button.

Please note:

• Individual axially parallel linear dimensions can also be determined with the Variable dimensions function or the Linear dimension, axially parallel function iin the Individual dimensions menu.
• Use the Half-section-dimension, axially parallel function in the Individual dimensions menu for creating axially parallel half-section dimensions.
• For half-section dimensions you need to specify the symmetry axis before selecting the elements to be dimensioned!

6. Determine the next points in the dimensioning structure.

Please note:

For the creation of individual, linear dimensions running parallel to a reference axis you can also use the Variable dimensions function or the Create new linear dimension, with reference axis function in the Individual dimensions menu.
