Measurements
Measurement mode of DG Kernel views allows
adding items, which display distances between points, coordinates of a selected
point and angles. A measurement can also be modified programmatically to display
a single line of text so that it will act as a text label attached to the
specified surface.
To enter the measurement mode, make sure the view has focus (click into
the window) and press 'm' key. The measurement mode has several sub modes
and a "delete all" command. The component exits the measurement mode
automatically when the current operation is either completed or interrupted.
The Advanced > Measurements > Add context menu (right mouse click) options offer
a user interface for entering the mode.
DG Kernel components have two styles of measurements: Persistent measurements
and Transient (default) measurements
Transient measurements disappear once the measurement mode is exited. They can be
used to quickly check distances and avoid adding extra items obscuring the scene
Transient measurements style (default) can be re-activated programmatically by setting the
MeasurementsStyle property of
DG Kernel Context to 1.
Persistent
measurements are part of the model. Once added to the scene they persist during
viewing manipulations: rotations etc
To switch between the modes at runtime got to Advanced > Measurements > Style in
context menu (right mouse click)
Persistent measurements style can also be activated programmatically by
setting the MeasurementsStyle property of
DG Kernel Context to 0.
See Persistent Measurements topic for
more details
When MeasurementsShowOnMouseMove property of
DG Kernel Context is set to
true (false is the default) the component displays distance between the first
point of the measurement and the current position of the mouse during movement
from the first to the second point. The distance is measured along plane
parallel to plane of the screen and recalculated precisely after the second
point has been selected.
