MiniCAD Sample
MiniCAD sample demonstrates runtime modification of deprecated 3DS and SOR types of geometories based
on arc/line splines.
Running MiniCAD Sample
MiniCAD application loads by default MiniCAD.mdg model, which has two
top level objects the first object is a 3DS. The
second object is a Surface Of Revolution. The user can
load and save any DInsight model.
User Interface
Top Level Objects group of the dialogue allows switching between entities of the model.
Name edit box displays name of the current entity. Note that for simplicity
only top-level objects can be made current. ObjArray Sample
demonstrates browsing child objects.
Current joint edit box displays index of the current joint and segment next to it,
properties of which are displayed in Joint and Segment groups. For
3DS objects joints
are numbered normally in counter clockwise direction when looking from the end of z axis
(blue) starting from the joint nearest to positive X axis (red).
Depending on the type of the current object the dialogue displays either "Cross
Position" group (3DS) or angle range for SOR.
When "Knot" check box in "Cross Position" is off, edit box of
cross position group allows changing the current cross position, where all parameter
values will be applied. To enter the new position press Tab key
or otherwise switch focus out of the edit box. The relevant data in the dialogue will
be updated immediately. Turning "Knot" check box on sets cross
position to value of the current knot. Current knot index will be visible
in Cross Position group in this situation. When "Knot" check box is on,
switching focus will change value of the current knot. This allows changing z
dimension of the entity.
Angle range group for SOR objects is quite
straightforward.
Edit boxes of "Joint" group allow to change coordinates of the
current joint for both types of objects.
Segment group displays radius or curvature of the arc
which has the current joint as its first end. Segment Group is available only when
current segment is an arc.
Move Entity group allows changing position and orientation of local frame
of the entity and hence position of the entity with respect to other entities.
The Options dialogue allows to increase or reduce
Geometrical resolution.
Modifying the model
Segment group displays properties of
the segment which is next to the
point (in CCV direction for closed strip).
To enter a new value of properties, press "Apply" button. If entered values are
valid, the model will change in 3D.
Cross position is important for modifications. When cross position coincides with a
knot all changes apply to ends of 3d edges. Otherwise if it is a straight line,
the whole 3d edge will be
translated.
To view or modify z axis knot values turn "Knot" check box on in the Cross Position
group.
To use Move Entity group, enter values in edit boxes and press the Move Button. The
entity will change it position relatively to global axes.
