Hatches and Fills
If you would like to use already created construction entities as a contour, make sure to be in the constrained
drawing mode rather than in free drawing. See that the icon appears in the automenu.
The first step in the manual definition of a hatch contour is selection of the start point. One can select an
appropriate 2D node, or create one by clicking at an intersection of construction lines. Next, define the
contour sequentially.
The following options become available after selecting a node:
,
Free Mode On/Off toggle
Close Contour
Change arc direction (available when making contour
along a circle)
Select Graphic line (available after selecting a node)
Select Node
Select Line
Select Circle
Select Ellipse
Select Spline
Find contour automatically (made of graphic lines).
The option becomes available after selecting a node,
and terminates if more than two graphic lines meet in
the node.
Delete last Contour segment
Cancel selection
The simplest way of defining a hatch contour is using the bar that will let you traverse the contour
by following graphic lines. Note that this way can only be used when the hatch contour follows graphic lines.
In the case of multiple choices, the cursor should point at the desired graphic line when pressing the
bar.
For faster selection, use the option that automatically searches for the next contour line until the contour
is closed or a dubious situation is encountered (such as branching lines).
