Connections
The subgraph objects that contains connection points can be connected with connections.
Connections are drawn by dragging MB2 from one object to the other. The connection point that
is closest to the cursor when you press or release the mouse is selected.
Connections are characterized by type, line width, 3D and color.
Type
Type is selected from the menu under 'Connections'.
Straight
A straight line connection between the connection points.
StraightOneArrow
A straight line connection with one arrow.
Routed
Connection with horizontal and vertical lines. The route and breakpoints of the connection
are caculated to avoid collision with other subgraph objects (that don't has the attribute
NoConObstacle set).
Grafcet
There are a number of connections used when drawing grafcet sequences: StepDivergence,
StepConvergence, TransDivergence and TransConvergence. These can be used, together with the
subgraphs under the folder Grafcet in the subgraph palette, if you want to view a grafcet
sequence in a graph.
Round corners
For connections of type routed, you can choose to have rounded corners, and you can also
specify the radius of the rounding. This is chosen in the menu, 'Connections/Corners' and
'Connections/CornerRoundAmount'.
Color
The color of the connection is selected as fill color, that is with MB1 in the color palette.
Border
With 'Border', the connections is draw with black borderlines.
3D
With '3D', a lighter shadow is drawn on the upper side, and a darker on the lower side. Only
implemented for connections of type Routed and round corners.
Width
The width is chosen in the tool panel in the same way as for lines.
Ramification
If a connection is drawn from a component and released in the working area, a component of type
ConGlue is created at the end of the connection. ConGlue has four connection points and works
either as a termination, or as a ramification of the connection, or as a possibility to
influence the route of the connection. By drawing new connections from ConGlue, new connections
are created, and the ConGlue object adapts its color and shape after its connected connections.
ConGlue is also found in the subgraph palette under 'Other'.
