Customizing Drawing Direction. Defines the itemization direction for zones: left to right or right to left, top down or bottom up. First displayed symbol. Specifies, which of the zone-defining symbols, (the one of the X or Y axis), will come first in its marking. Orientation. This parameter defines the orientation of the drawing format. The orientation can be Portrait or Landscape. Origin. The following parameters define the location of the origin of the drawing coordinate system. X. Defines the X coordinate of the drawing lower-left corner. Y. Defines the Y coordinate of the drawing lower-left corner. The coordinate values are defined in the same units as used for creating the drawing. These are defined under the “Units” item. Scale. Defines the drawing scale. An arbitrary value of the scale can be defined, or otherwise be selected from the list. It is recommended to use scale only when actually necessary. In most cases, scaling is not necessary for the following reasons: 1. When outputting to a plotter or printer, the drawing size is not a concern. 2. Special tools are provided for scaling dimension notations of the whole drawing or a portion thereof, as described below. If it is still necessary to set a scale, it is better be done before starting creating the drawing. Changing the scale setting on an existing drawing may require manual editing of some of its elements. This is because scaling does not merely a proportional modification of all drawing element sizes. The scale in T-FLEX defines only the drawing lines locations, while, for instance, the size of dimension arrows and text will stay unchanged. Units. Defines the measurement units used by T-FLEX CAD. This parameter is selected from the list. This parameter affects several issues, such as the following: - Calculating dimension tolerances that is done differently in metric and inches systems; - The menu settings when defining roughness parameters and GD&T symbols for surfaces; - Output to a plotter; - Exporting different formats; - The way of converting dimension values, if a conversion system is assigned to the “Dimension scale” or ”Alternative scale" parameter on the “Dimensions” tab. When defining document parameters, one can use variables that will be stored in the drawing file. To do so, enter a variable name instead of a particular parameter value, whether numerical or string. The variable name must be entered in {braces}. If it is a string variable, its name must begin with “$” character. Pressing while in the intended input box allows selecting the variable from the list of already created ones. The variable values can be modified using the variable editor. 159
Fundamentals. Two-Dimensional Design “Font” Tab 160 This tab defines font parameters for all standard detailing elements unless already defined within the detailing elements themselves. These detailing elements are text, dimensions, roughnesses, leader notes and tolerances. Name. This parameter defines the name and type of the font. T-FLEX CAD supports two types of fonts: TrueType fonts ( ), that are standard for Windows, and vector fonts in SHX ( ) format. The TrueType and SHX fonts are distinguished in the font menu by the respective icons before the names. Size. Defines the vertical size of the font by capital letters, as, for instance, the height of the character “A”. Any font size is allowed, except 0. Line Spacing. This is the distance between two neighboring lines of a multi-line text. Line interval is set in relative units. To calculate the absolute value of the line interval, multiply this parameter by the font height. Character Spacing. Defines the additional distance between two neighboring characters in a string. This parameter value is also relative. To calculate the absolute value of the additional interval, multiply this parameter by the font height. Stretch. Defines the scale factor for the width of the font symbol. It is possible to specify any value for this factor except 0. Index scale. Defines the scale factor for calculating the size of the subscript and superscript fonts from the normal font size. Subscripts and superscripts are used, for example, for dimension tolerances and other indexes. Oblique Angle. This parameter defines the font slant angle. Any slant value is allowed, except for 0, 180, 360, etc. The normal (upright) font has the slant angle value of 90 degrees. Line Width. This parameter defines the thickness of the character contour lines. Fill. If set, then the characters are filled with color when applicable. Otherwise, they are drawn by contours only. The “Oblique Angle”, “Line width” and “Fill” parameters affect only vector fonts of the SHX format. An additional parameter for TrueType is Style. Defines the font style. This is a standard parameter of fonts and assumes the values supported by Windows, namely normal, semi-bold, italic, semi-bold italic. The settings on this tab affect the size of all detailing elements of the drawing (dimensions, text, roughnesses, GD&T symbols, leader notes), whose “Font” tab settings are “Set as default”. The elements will not be modified whose “Font” tab settings are explicitly defined.

“Font” Tab<br />
160<br />
This tab defines font parameters for all standard<br />
detailing elements unless already defined within the<br />
detailing elements themselves. These detailing elements<br />
are text, dimensions, roughnesses, leader notes and<br />
tolerances.<br />
Name. This parameter defines the name and type of the<br />
font. T-<strong>FLEX</strong> <strong>CAD</strong> supports two types of fonts:<br />
TrueType fonts ( ), that are standard for Windows,<br />
and vector fonts in SHX ( ) format. The TrueType<br />
and SHX fonts are distinguished in the font menu by<br />
the respective icons before the names.<br />
Size. Defines the vertical size of the font by capital<br />
letters, as, for instance, the height of the character<br />
“A”. Any font size is allowed, except 0.<br />
Line Spacing. This is the distance between two<br />
neighboring lines of a multi-line text. Line interval is<br />
set in relative units. To calculate the absolute value<br />
of the line interval, multiply this parameter by the<br />
font height.<br />
Character Spacing. Defines the additional distance between two neighboring characters in a string. This<br />
parameter value is also relative. To calculate the absolute value of the additional interval, multiply this<br />
parameter by the font height.<br />
Stretch. Defines the scale factor for the width of the font symbol. It is possible to specify any value for this<br />
factor except 0.<br />
Index scale. Defines the scale factor for calculating the size of the subscript and superscript fonts from the<br />
normal font size. Subscripts and superscripts are used, for example, for dimension tolerances and other<br />
indexes.<br />
Oblique Angle. This parameter defines the font slant angle. Any slant value is allowed, except for 0, 180,<br />
360, etc. The normal (upright) font has the slant angle value of 90 degrees.<br />
Line Width. This parameter defines the thickness of the character contour lines.<br />
Fill. If set, then the characters are filled with color when<br />
applicable. Otherwise, they are drawn by contours only.<br />
The “Oblique Angle”, “Line width” and “Fill” parameters affect only vector fonts of the SHX format. An<br />
additional parameter for TrueType is<br />
Style. Defines the font style. This is a standard parameter of fonts and assumes the values supported by<br />
Windows, namely normal, semi-bold, italic, semi-bold italic.<br />
The settings on this tab affect the size of all detailing elements of the drawing (dimensions, text,<br />
roughnesses, GD&T symbols, leader notes), whose “Font” tab settings are “Set as default”. The elements<br />
will not be modified whose “Font” tab settings are explicitly defined.
