-
-//! 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.
-//!

-//! flyout | +++

-//! o---flyout---
-//! center ^

-//! line
-//! </pre>
-//!
-//! 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).
