| double dxf_dimension_struct::angle |

Group code = 50.
Definition at line 237 of file dimension.h.
Referenced by dxf_dimension_get_angle(), dxf_dimension_read(), and dxf_dimension_set_angle().
In addition, all dimension types have an optional group (group code 51) that indicates the horizontal direction for the Dimension entity.
This determines the orientation of dimension text and dimension lines for horizontal, vertical, and rotated linear dimensions.
The group value is the negative of the Entity Coordinate Systems (ECS) angle of the UCS X axis in effect when the Dimension was drawn.
The X axis of the UCS in effect when the Dimension was drawn is always parallel to the XY plane for the Dimension's ECS, and the angle between the UCS X axis and the ECS X axis is a single 2D angle.
The value in group code 51 is the angle from horizontal (the effective X axis) to the ECS X axis.
Entity Coordinate Systems (ECS) are described elsewhere in this documentation.
Group code = 51.
Definition at line 241 of file dimension.h.
Referenced by dxf_dimension_get_hor_dir(), dxf_dimension_read(), and dxf_dimension_set_hor_dir().
Linear dimension types with an oblique angle have an optional group (group code 52).
When added to the rotation angle of the linear dimension (group code 50) this gives the angle of the extension lines.
Group code = 52.
Definition at line 260 of file dimension.h.
Referenced by dxf_dimension_get_obl_angle(), dxf_dimension_read(), and dxf_dimension_set_obl_angle().
The optional group code 53 is the rotation angle of the dimension text away from its default orientation (the direction of the dimension line).
Group code = 53.

Dimension type.
Values 0–6 are integer values that represent the dimension type.
Values 32, 64, and 128 are bit values, which are added to the integer values (value 32 is always set in R13 and later releases).
0 = Rotated, horizontal, or vertical.
1 = Aligned.
2 = Angular.
3 = Diameter.
4 = Radius.
5 = Angular 3-point.
6 = Ordinate.
32 = Indicates that the block reference (group code 2) is referenced by this dimension only.
64 = Ordinate type.
This is a bit value (bit 7) used only with integer value 6.
If set, ordinate is X-type; if not set, ordinate is Y-type.
128 = This is a bit value (bit 8) added to the other group 70 values if the dimension text has been positioned at a user-defined location rather than at the default location.
Group code = 70.
