-//! -//! 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). -//! -class AIS_Dimension : public AIS_InteractiveObject -{ -protected: - - //!

PrsDim_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 PrsDim_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). +class PrsDim_Dimension : public AIS_InteractiveObject +{ + DEFINE_STANDARD_RTTIEXT(PrsDim_Dimension, AIS_InteractiveObject) +protected: + + //!
