We will begin creation of a line pattern from the main element – the periodic part. The descriptor of the
periodic part will be the drawing depicting the cross with two strokes, on either side. The points at which this
part connects to its neighboring line pieces are marked by the named nodes, “Start” and “End”, as shown on
the diagram.
A node name is defined by the command “EN: Edit Node”, the path name – by the command
“EC: Edit Construction”.
The lines constituting the periodical part can be of
various types, color and width, depending on the
desired appearance of the custom line. In this
example, the crosses on the line ought to be blue.
Therefore, we will make the cross strokes blue,
while the lateral strokes - black.
Next, we need to decide whether to prescribe the
path for hatches. Suppose, this line may be used
in the future for creating hatches, so that the hatch
or fill lines are not allowed to overlap the cross strokes. For this purpose, we will create a named path,
“Polyline”, starting and ending in the named nodes “Start” and “End” and passing as shown on the figure.
After describing the periodical part, let’s proceed to creating the next line element – the center part. To create
it, we need to switch to another page of the pattern template.
The pattern’s center part will include the text
“Test” with two strokes on either side. The text
can be created by any text entity type (the
command “TE: Create Text”). The start and end
of the center part are defined by the named nodes
“CenterStart” and “CenterEnd”. Additionally, we
will create a named path “CenterPolyline” for
hatches based on this line, as shown on the figure.
Similarly, we will create description of the tail and
head of the line on separate pages, as shown on
the figure. We will have to use a hatch to create
the filling.
No additional paths for hatches will be created. In
this case, the contour of a hatch bounded by this
line type will follow the lines connecting the
border nodes of these line elements.
What is left to do before using the created
template is to save it in the folder …\Program\
LinePatterns under the name “Custom
line sample.grb” and restart T-FLEX CAD.
After restarting, the new line with this name will
appear in the list of line types. It can be used just
like a standard line type.
