A linear dimension is a graphic object defined by three points: the point of origin of the first extension line, the point of origin of the second extension line, the point that specifies the height of the dimension line.
Type
Specify the type of quota. The linear dimensions can be horizontal, vertical or aligned.
Value
Specify the dimension value or choose Automatic to automatically read the dimension value.
Text
Specifies the dimension text. Leave this field blank to use the format specified in the style or directly specify the format.
- Format
-
A string with the format of the dimension text must be specified in the box. The format string consists of zero or more directives and common characters. A directive is formed by the character '@' followed by a character that determines the substitution that must take place. All common characters are copied unchanged. The directives are as follows:
@V
Specifies the location where the dimension value is to be inserted.
@U
Specifies the location where the unit of measure is to be inserted.
@T
Specifies the position at which tolerance values are to be inserted.
@F
Specifies the position at which the frequency values are to be entered. This directive is used when dimension is used in diagrams. It converts the values of the time axis into frequency values and adds them to the dimension text.
Example:
If the value of the dimension is 10 and the unit of measurement is in millimetres, the following format strings will produce the following text string:
R.@V -> R.10
@V@U -> 10mm
Tolerance
Specify tolerance values or choose By Style to use the values set in the style.
- Mode
-
Select None to not enter tolerance values. Select Absolute to have absolute tolerance specifications; the tolerance values will be added to the value of the quota. Select Relative to have relative tolerance specifications; in this case the tolerance values will be preceded by the sign.
- Positive
-
Specify the positive tolerance value.
- Negative
-
Specify the negative tolerance value.
Style
Select the dimension style from the proposed list or create a new style. See Style of Dimension objects.
Start point
Specify the coordinates of the point where the first extension line begins.
- X
-
Specify the horizontal position.
- Y
-
Specify the vertical position.
End point
Specify the coordinates of the point where the second extension line begins. The coordinates can be specified in the following ways:
- In absolute coordinates
-
Specify the horizontal position in the X box and the vertical position in the Y box.
- In coordinates relative to the point where the first extension line begins
-
Specify the distance from the origin point of the first extension line to the Dx and Dy fields.
- In polar coordinates with respect to the point where the first extension line begins
-
Specify the length of the line and the angle it forms relative to the x axis in the Segment Length and Angle fields.
Height
Specify the height of the dimension line.
