Defaults to twice the arrowhead-width

Style for arrowhead on end of leader-line. Currently supported values are :none, :wedge (the Default), and :double-wedge.

Style for arrowhead on end of leader-line. Currently supported values are :none (the Default), :wedge, and :double-wedge.

Defaults to half the character-size.

The left front bottom and right rear top corners, in global coordinates, of the rectangular volume bounding the tree of geometric objects rooted at this object.

Size (glyph height) of the label text, in model units. Defaults to 1.

Determines the text which shows up as the dimension label. Defaults to the dim-value, which is computed specially in each specific dimension type.

Indicates where to position the text in the case when outside-leaders? is non-nil. Defaults to :center

Determines where the text will start. Defaults to halfway between start-point and end-point.

. The dim-text-start is offset by this vector, in model space. Defaults to #(0.0 0.0 0.0)

2D distance relative to the base-plane-normal. Can be over-ridden in the subclass

This names the DXF font for this general-note. Defaults to (the font).

The start of text will be offset by this amount for DXF output. Default is 2.

The scale factor for DXF character size vs PDF character size. Default is 0.8

Adjusts the character width for DXF output. Defaults to the text-x-scale.

Indicates which direction the witness lines should take from the start and end points. The Default is NIL, which indicates :rear (i.e. ``up'') for horizontal-dimensions and :right for vertical-dimensions

Font for the label text. Defaults to "Helvetica"

Indicates the length of the full leader when outside-leaders? is nil. This defaults to nil, which indicates that the full-leader's length should be auto-computed based on the given start-point and end-point.

Indicates whether the object should effectively be a hidden-object even if specified in :objects. Default is nil.

Points to a pre-existing image file to be displayed instead of actual geometry for this object. Defaults to nil

. For multi-line dim-text, this justification is applied.

Indicates whether the first (or only) leader line should be displayed. The Default is T

Indicates whether the second leader line should be displayed. The Default is T

Indicates the length of the first leader for the case when outside-leaders? is non-NIL

Indicates the length of the second leader for the case when outside-leaders? is non-NIL

Amount of gap between leader lines and dimension text, when the dimension text is within the leader. Defaults to half the character-size.

This is synonymous with the orientation.

If non-nil, this function gets invoked when the user clicks the object in graphics front-ends which support this functionality, e.g. SVG/Raphael and X3DOM.

Indicates the absolute Rotation Matrix used to create the coordinate system of this object. This matrix is given in absolute terms (i.e. with respect to the root's orientation), and is generally created with the alignment function. It should be an orthonormal matrix, meaning each row is a vector with a magnitude of one (1.0).

Currently can be :bubble, :rectangle, or :none. Default is :none.

Indicates the default length of the outside-leaders as a multiple of arrowhead-length. Defaults to 3.

Indicates whether the leader line(s) should be inside or outside the interval between the start and end points. The default is NIL, which indicates that the leader line(s) should be inside the interval

The root-level node in this object's ``tree'' (instance hierarchy).

All objects from the :objects specification, including elements of sequences as flat lists. Any children which throw errors come back as a plist with error information

Determines how the name of objects of this type will be printed in most places. This defaults to the name-for-display (generally the part's name as specified in its parent), followed by an index number if the part is an element of a sequence.

Indicates whether the text is to the right or above the leader line, rather than in-line with it. Default is T.

Where applicable, determines whether text direction follows leader-line direction

Adjusts the character width for the dimension-text and currently only applies only to PDF output

GDL

View object which will use this dimension. Defaults to NIL.

Additional objects to display in Tatu tree. Typically this would be a subset of hidden-children. Defaults to NIL.

Indicates whether to display a witness line coming off the end-point. Default is T

Distance the witness line(s) extend beyond the leader line. Default is 0.3

Distance from the start-point and end-point to the start of each witness-line. Default is 0.1

Length of the witness lines (or of the shorter witness line in case they are different lengths)

Indicates whether to display a witness line coming off the start-point. Default is T

Indicates in global coordinates where the center of the reference box of this object should be located.

May contain keywords and values indicating display characteristics for this object. The following keywords are recognized currently:

:color

color keyword from the *color-table* parameter, or an HTML-style hexidecimal RGB string value, e.g. "#FFFFFF" for pure white. Defaults to :black.

:line-thickness

an integer, defaulting to 1, indicating relative line thickness for wireframe representations of this object.

:dash-pattern

(currently PDF/PNG/JPEG only). This is a list of two or three numbers which indicate the length, in pixels, of the dashes and blank spaces in a dashed line. The optional third number indicates how far into the line or curve to start the dash pattern.

Z-axis dimension of the reference box. Defaults to zero.

Y-axis dimension of the reference box. Defaults to zero.

X-axis dimension of the reference box. Defaults to zero.
