Projection Line Text

Projection line text (PLTX) is set and manipulated in a similar way to dimension line text. For example, the commands:

PLTX ’PUMP /1501A’

PLTX ’PUMP /1501B’

(each at the appropriate dimension point level) can be used to produce text.

Note also:

Projection line text axes are oriented relative to the projection line. The orientation is controlled by setting the PTOF attribute.

Example

PTOF -5 -5

The example illustrates the projection line text offset.

Other options are:

Projection line text is justified ‘towards’ the appropriate dimension point by default, but can be justified ‘away’ from the dimension point or can be centered on the projection line, using the commands:

PJUST AWAY

PJUST CENTRE

The initial value of PJUS is cascaded down from LAYE level.

Projection text angle can be controlled using the PTANGLE attribute. The attribute is available both at dimension and dimension point level. Possible settings are:

PTANGLE HORIZ

PTANG VERT

PTANG STAN

PTANG DEF

The HORIZONTAL and VERTICAL settings cause the projection line text to be drawn respectively horizontally or vertically in the VIEW. In these cases, the projection line is not extended automatically to underline the text but only overshoots the dimension line by the distance specified by the OSHT attribute.

The STANDARD setting gives the projection line text parallel to the projection line, the default value for Dimension elements.

The DEFAULT setting is only available at Dimension Points. The PTANG setting can be taken from the Dimension element (LDIM or ADIM). Otherwise the setting at the Dimension Point is used, which is the default setting for Dimension Points.

The standard character height for dimension line and projection line text is 4mm (cascaded from LAYE level), but this can be varied by commands, for example:

Initial settings of these attributes are cascaded down from LAYE level.

Other text attributes (present at Dimension and Dimension Point level) are:

Initial settings of these attributes are cascaded down from LAYE level. Refer to Miscellaneous Text Facilities for further information.

Dimension line and projection line text can be modified through use of the EDTEXT command. In the examples, the target string is ‘ACCESS DPACE’, = ‘ACCESS SPACE’ mistyped:

Note:
When modifying intelligent text the intelligent text code itself must be specified, not the resultant text. The EDTEXT command is described. Refer to Miscellaneous Text Facilities for further information.
