Set Parameters for New Dimensions (3-D)

3-D Dimensioning + Text > Tools > Dimension

When you specify the dimensioning settings with the functions

Set parameters for new general dimensions

Set parameters for new parametric dimensions

Set parameters for new constraint dimensions

, the Dimension parameters window is displayed. It consists of the following tabs:

These tabs enable you to define all dimensioning parameters individually.

  1. Choose the desired settings or enter the desired values.
  2. Click OK to exit the window.

The settings will be regarded as the default settings for all subsequently created dimensions.


Dimension lines

In this tab you define parameters for the dimension lines and the projection lines. These are

Please note:


Dimension line terminations

In this tab you can preset the symbol, length, width and colour of dimension line terminations. The settings can be applied separately for


Dimension figure

Here you define the representation and properties of the dimension figure, e.g.

The font parameters of the superscript numbers correspond to those of the dimension figure, apart from one value for superscription and font size. Superscription and font size depend on the font size of the dimension figure. The calculation factors (superscription 50%, font size factor 66%) are pre-programmed, fixed values and cannot be changed.

 

Use the same-named function to

 

Please note:


Dimension texts

Auxiliary texts can be assigned to the dimension figure, being either placed in front of it or appended to it. In the Dimension text tab, you define whether you want these auxiliary texts to be displayed and you specify the properties of the auxiliary texts. These are:


Tolerance

Here, you define the tolerance parameters. These are:

  • the colour, font, encoding (character set) and height,
  • the number of decimal places and the representation of non-relevant places,
  • the position of the tolerance in relation to the dimension line and dimension figure
  • the arrangement of the tolerances (1 line or 2 lines)


(1) 1st tolerance, (2) 2nd tolerance


Symbol

Dimensioning symbols, e.g. the diameter sign, can be assigned to each dimensioning. In this tab, you define the size of the symbols and their position in relation to dimension figure and dimension line.

Use the Edit dimension figure function to assign a symbol to a dimension figure.


Grid

When placing dimension figures and dimension lines and rotating circle, radius and diameter dimensions the grid specified in this tab will be used.

If you want to use other grid line spacings or switch the grid off, change the settings accordingly.


Further Settings

Use this tab to specify further dimension parameters, such as:

When you dimension an object, it can occur that dimension figures collide with part edges or dimension lines of a different dimension. If you activate the corresponding checkboxes, HiCAD will automatically create exclusions in the corresponding dimension line or part edge in order to improve the legibility of the dimension figure. The size of the exclusion is normally automatically determined by HiCAD. If the exclusion is too small, you have the option to additionally set an allowance for the height and width of the exclusion rectangle. The allowance is absolute and scale-independent. It can also be applied if the dimension lies on a hatching.

If the option Dimension figure interrupts body lines is active, you can determine on the System tab, in the Printed representation area, that dimension figures will be shown with white rectangular backgrounds in printouts.

With and without allowance for exclusion

Shortening of the dimension line by setting its maximum length for large radiuses in order to shorten the dimension line from the centre point; can be lengthened by moving of the dimension line.


System

Use this tab to specify settings which will globally apply to the current workstation and will be used for all subsequently created dimensions.

Dimension figure representation

Use these options to specify which separator for decimal places (point or comma) you want to use and according to which rules you want to round the dimension figure up or down. If you select "mathematical", the dimension figure will be rounded according to the common mathematical rules. If required, the dimension figure can also be generally either rounded up or down. Default setting is: Point, Mathematical.

Printed representation

If the option Dimension figure interrupts body lines is active, you can determine on the System tab, in the Printed representation area, that dimension figures will be shown with white rectangular backgrounds in printouts.

This setting will be applied immediately. A restarting of HiCAD will not be required.

Behaviour during creation

Here you specify what you want HiCAD to do if a processing plane is active, or if a selected dimension point is not clearly identifiable (e.g. because of overlapping points).

Example of an arc projection. Left: Without processing plane; Right: With projection onto processing plane


If the checkbox is not active, the foremost point is always selected.

 

Behaviour when changing scale

Here you can specify the behaviour of the dimension lines in case of scale changes:

Option

Effect

Do not adjust

The points of the dimension line are scaled in the same way as the corresponding part.

Scale

The points of the dimension line are adjusted scale-independently.

Scale selectively

This is the default setting. The points of the dimension line are only adjusted scale-independently if they are located outside the part. Otherwise, HiCAD proceeds in the same way as with the first option (Do not adjust).

(1) Original, Scale 1:1, (2) Scale 1:5, Do not adjust, (3) Scale 1:5, Scale

The following image illustrates the Scale selectively option. The dimensions belong to the left cuboid, with the base point highlighted in red lying outside this cuboid. If the Scale selectively option is active, the length of the projection line starting from this base point remains unchanged, while the other lines are adjusted accordingly in case of a scale change.

 

Settings for parametric dimensions

These options are available for parametric dimensions and HCM dimensions. They enable you to define the behaviour of the dimension line and dimension figure during zooming, via the checkboxes

 

The System tab is not shown if you want to apply subsequent changes to settings for individual dimensions or dimension elements.
