Setting and Updating Attributes

Home > 19 Dimensions > Setting and Updating Attributes

The dimensions are managed by styles, there are two toolbars:

Short

This toolbar alows to set the current dimension style.

The first icon allows to change all parameters of the dimension style.

The second icon sets the current style to one entity or to the selection group.

The pull down menu allows to select the current dimension style that would be used to create a new dimension.
Extended

This toolbar alows to set the main parameters.

1. Allows to change all parameters of the dimension style.

2. Sets the current style to one entity or to the selection group.

3. The pull down menu allows to select the current dimension style that would be used to create a new dimension.

NOTE: Options 4 - 11 are only available when the dimension style is set to nostyle.

4. Sets font of the text dimension

5. Size of text dimension (in Meter)

6. Colour of text dimension

7. Tick mark setting

8. Size of tick mark

Set the attributes of dimension lines and text.

\uadim

You can select entities to update with the current dimension style.

\adim

It consists of 4 tabs Appearance, General, Text, Format. The details of their contents are given below.

General Attributes (General tab)

The parameters of the Appearance tab are:

Attribute

Description

line

By Distance

Color: Click on the color rectangle to access the color selector.

You can choose between the 255 colors of ARC+. Click on the color of your choice and then click OK to select it.

color of the dimension line

Click on the color rectangle to access the color selector. You can choose between the 255 colors of ARC+. Click on the color of your choice and then click OK to select it.

The parameters of the general tab tab are:

Attribute

Description

entities to dimension

Choose between the three options: all, walls only (wall entities only) or selection (selected entities only)

openings

You can specify how wall openings should be dimensioned:

none: do not dimension openings

+ width: indicate width only

+height: indicate width + height

+Sill Ht. indicate the width + height + sill

wall details

Dimensions of wall faces, wall axes, or both

Sill label

Set label text (e.g. Sill=) if any

LAYER

You can click the Layer... button to set the default placing layer of dimensions. This will open the following layer selector below.

$image\ebx_1923521523.gif$

Specify the desired layer in the list. If it does not appear, you must add it by clicking on the $image\ebx_31633124.gif$ icon, and then specifying its name and number. The $image\ebx_713262271.gif$ icon enables you to create a new layer group.

If you want the dimensions to be placed on the current working layer instead of the specified layer, click on the Current button.

Setting Wall Elements for Dimensioning

The entities to dimension parameters determine the type of entities to dimension - all entities, walls only, or the openings also. You also specify which wall details to dimension—faces, axes, or both. When you dimension openings, you can include:

Width

Add height of the opening

Add sill height

(You can specify a label of up to five characters for the sill height, for example Sill=or the abbreviation S. Remember to add a space character if you want a space between the tag and the sill dimension).

When you dimension walls, the system uses the parameters you set to create a dimension line from wall ends, at junctions with walls as well as openings (if you chose this option). If you set a dimension line along wall faces, and the two sides of the wall are of unequal length, the side closer to the dimension line is dimensioned. Dimensions of a T-junction are displayed when the dimension line is on the same side of the wall as the junction.

sill

The parameters of the text tab tab are:

Attribute	Description
Font	Choose the name of the font of caracters (see Setting text attributes (\atext))
Style: Italic, Bold	Display parameters of the caracters (Font TrueType™ only)
Justification	Horizontal alignment of text when it is too large to fit in between the two extension lines.
Location	Vertical alignment of text with respect to the dimension line
Color	Click on the color rectangle to access the color selector. You can choose between the 255 colors of ARC+. Click on the color of your choice and then click OK to select it
Height	Text size
Text mode	fixed or scaled
proportional	Specify text spacing by entering a value from 1 to 32: proportional distance between characters
Width of text	Indicate value greater than 0.1 (ARC+ fonts only)
Slant	Set text angle between -45 and +45 (ARC+ fonts only)

You can also customize the automatic repositioning of the dimension text. To display the Automatic Repositioning dialog box, click the Parameters... button.

$image\ebx_-726553584.gif$ HINT: Refer to the chapter 19 of volume 2 to familiarize yourself with the automatic repositioning parameters.

Dimension format (Format tab)

The third tab manages the format of the dimension text.

Attribute	Description
Unit	Measurement unit: millimetres, centimetres, or metres; decimal inches or feet; feet & decimal inches; fractional inches; feet & fractional inches.
Accuracy Preferences	Number of digits displayed after the separator. This parameter concerns all the decimal dimensions (millimetres, centimetres, metres, foots, decimal inches).
Display trailing zeros	Activated, the trailing zeros are displayed. e.g. 1.500 instead of 1.5, if the accuracy is of 4.
Mix meters and centimeters	This parameter concerns the meter unit only. Activated, the zero of the whole part is not displayed if the distance is less than 1 meter. e.g. 5 instead of 0.5 for 50 cm
Display zero inches	Activated, displays zero inches. e.g. 1’ 0/16’’ instead of 1’.
Fraction	Controls the fractional accuracy. The permitted values are: none, 1/2, 1/4, 1/8, 1/16, 1/32 or 1/64. This parameter can be used for the fractional units only (feet, inches).
Extra accuracy	Enables the display of additional digits after the separator for the accuracy certain values. The permitted values are:.01, .25, .5, .1, Off. These digits are displayed in superscript. e.g. 30.55
Big superscript digits	Controls the type of superscript for additional accuracy. (ARC+ font only).
Sill on the wall	This parameter enables to decide whether the sill label (e.g.: sill=90) should be placed close to the wall (checkbox checked) or close to the dimension (checkbox unchecked)
separator	Choose dot or comma

Automatic Repositioning by Settings

When you dimension entities automatically, there may certain situations in which there is not enough room to locate all of the dimension text on the line. If a dimensioned segment is too short to insert the text (according to the current settings), the system will automatically align the text differently from the settings—for example, to the right or up instead of centering it. A new option enables you to control the priorities used by the system to relocate the text (refer to priority settings in table above).

Operation

In the Dimension Attributes dialog box choose the text settings option. Use the text location and priority options in the Dimension Text Attributes dialog box to set the parameters for placing dimension line text. To display the Setting Automatic Reposition dialog box choose the automatic repositioning option.

$image\ebx_1993070522.gif$

In cases where text will not fit on the dimension line, you can set up to four priorities for text displacement. The system will attempt to reposition the text according to the priorities.

If the text cannot be repositioned according to any of the settings, it will be displayed in a different color (indicating that it is overwritten by adjoining texts).

When Automatic Repositioning is on, it overrules the location and priority settings.

When the automatic repositioning option is off, text is displaced according to the priority selection in the Dimension Text Attributes dialog box: left, center, or right. (See Moving dimension text command \dimmt.)
