Creating Drawing Lines
GRAPHIC LINES
Graphic lines are the base graphic elements that constitute the drawing image. The analogy for the graphic
lines found in conventional drafting is the lines drawn in ink. Graphic lines are created based on construction
lines and nodes. By “lines”, we mean straight or curved line entities described below.
The various types of graphic lines can be defined by:
A line segment between two nodes. The graphic line limits are defined by the location of these nodes.
A full construction entity. This graphic line can only be defined by the underlying construction entity. The
construction entity can be of any type except straight line as the latter is infinite.
A portion of construction entity between two nodes. This type of graphic entity is defined by the
underlying shape-defining construction entity and two nodes defining the line limits.
Graphic entities can be created with user-defined line types.
Creating Graphic Lines
Graphic lines are created in the command “G: Create Graphic Line”. Call the command via:
Keyboard Textual Menu Icon
“Draw|Graphic Line”
On entering the command, the following options will be available in the automenu:
,
Free mode on/off toggle
Set Graphic line parameters
Select existing Node
Select straight Construction Line
Select full circle
Select full Ellipse Contour
Select full Spline or Polyline Contour
Delete last Contour segment
Execute Edit Graphics command
Cancel selection (available only when selecting a
construction entity)
Exit command
