AIS_Dimension is a base class for 2D presentations of linear (length, diameter, radius) and angular dimensions.
The dimensions provide measurement of quantities, such as lengths or plane angles. The measurement of dimension "value" is done in model space "as is". These "value" are said to be represented in "model units", which can be specified by user. During the display the measured value converted from "model units" to "display units". The display and model units are stored in common Prs3d_Drawer (drawer of the context) to share it between all dimensions. The specified by user units are stored in the dimension's drawer.
As a drawing, the dimension is composed from the following components:
- Attachment (binding) points. The points where the dimension lines attaches to, for length dimensions the distances are measured between these points.
- Main dimension line. The which extends from the attachment points in "up" direction, and which contains text label on it with value string.
- Flyouts. The lines connecting the attachment points with main dimension line.
- Extension. The lines used to extend the main dimension line in the cases when text or arrows do not fit into the main dimension line due to their size.
- Arrows.

Being a 2D drawings, the dimensions are created on imaginary plane, called "dimension plane", which can be thought of as reference system of axes (X,Y,N) for constructing the presentation.
The role of axes of the dimension plane is to guide you through the encapsualted automations of presentation building to help you understand how is the presentation will look and how it will be oriented in model space during construction.
Orientation of dimension line in model space relatively to the base shapes is defined with the flyouts. Flyouts specify length of flyout lines and their orientation relatively to the attachment points on the working plane. For linear dimensions: Direction of flyouts is specified with direction of main dimension line (vector from the first attachment to the second attachment) and the normal of the dimension plane. Positive direction of flyouts is defined by vector multiplication: AttachVector * PlaneNormal. For angular dimensions: Flyouts are defined by vectors from the center point to the attachment points. These vectors directions are supposed to be the positive directions of flyouts. Negative flyouts directions means that these vectors should be reversed (and dimension will be built out of the angle constructed with center and two attach points).
The dimension plane can be constructed automatically by application (where possible, it depends on the measured geometry). It can be also set by user. However, if the user-defined plane does not fit the geometry of the dimension (attach points do not belong to it), the dimension could not be built. If it is not possible to compute automatic plane (for example, in case of length between two points) the user is supposed to specify the custom plane.
Since the dimensions feature automated construction procedures from an arbitrary shapes, the interfaces to check the validness are also implemented. Once the measured geometry is specified, the one can inquire the validness status by calling "IsValid()" method. If the result is TRUE, then all of public parameters should be pre-computed and ready. The presentation should be also computable. Otherwise, the parameters may return invalid values. In this case, the presentation will not be computed and displayed.
The dimension support two local selection modes: main dimension line selection and text label selection. These modes can be used to develop interactive modification of dimension presentations. The component highlighting in these selection modes is provided by AIS_DimensionOwner class. Please note that selection is unavailable until the presentation is computed.
The specific drawing attributes are controlled through Prs3d_DimensionAspect. The one can change color, arrows, text and arrow style and specify positioning of value label by setting corresponding values to the aspect.
Such set of parameters that consists of:
- flyout size and direction,
- user-defined dimension plane,
- horizontal and vertical text alignment can be uniquely replaced with text position in 3d space. Therefore, there are methods to convert this set of parameters to the text position and vice versa:
- If the fixed text position is defined by user, called SetTextPosition (theTextPos) method converts this 3d point to the set of parameters including adjusting of the dimension plane (this plane will be automatic plane, NOT user-defined one). If the fixed text position is set, the flag myIsFixedTextPosition is set to TRUE. ATTENSION! myIsFixedTextPosition fixes all parameters of the set from recomputing inside SetMeasureGeometry() methods. Parameters in dimension aspect (they are horizontal text position and extension size) are adjusted on presentation computing step, user-defined values in dimension aspect are not changed. But plane and flyout as dimension position parameters are changed by SetTextPosition() method according with user-defined text position. If parameters from the set are changed by user with calls of setters, it leads to disabling of fixed text position (myIsFixedTextPosition is set to FALSE). If the fixed text position is set and geometry is changed by user (SetMeasureGeometry() method is called) and the geometry doesn't satisfy computed dimension plane, the dimension is not valid.
- If the set of parameters was set by user (may be without the user-defined plane or with it), it can be converted to the text position by calling the method GetTextPosition(). In this case the text position is NOT fixed, and SetMeasureGeometry() without user-defined plane adjusts the automatic plane according input geometry (if it is possible).
