Drawing regular lines
A regular line is a straight line connecting
two points in a plane. You can draw a regular line by defining its starting
and end points. Then they are automatically connected in a straight line.

Dy).

Attributes
- Length Appears as L in the contextual edit bar and
as a read-only Length field in the
- Angle The angle between the line and the x-axis. Appears
as Angle in the contextual edit bar and as a read-only field
(the Data column) in the .
- Absolute Dx
The horizontal distance between the projections of the starting and
end points of the line along the x-axis. The Dx value is the x-axis
coordinate value of the line's end point less the x-axis coordinate
value of the line's starting point.
- Absolute Dy The vertical distance between the projections
of the starting and end points of the line along the y-axis. The Dy
value is the y-axis coordinate value of the line's end point of less
the y-axis coordinate value of the line's starting point.
- Relative Dx
and Dy Appear on the contextual edit bar only when you are
dragging a line to reposition it. Dx/Dy is the relative horizontal/vertical
offset distance between the line's original position and the line's
new position as projected on the respective coordinate axis. The Dx/Dy
value is the Ox/Oy coordinate position of the repositioned line less
the proportional Ox/Oy coordinate position of the original line.
- Style For more about styles, see Formatting styles, colors
and templates.
- Id A system-generated, unique object identification number.
Appears in the Id column in the tabular area.
NOTE: For help on how to use the Select Quadrant
buttons on the contextual
edit bar, see Automatic computation of angles.
Control
points
A regular line has two control points: starting
and end. During drawing, he following pointers appear:
About to draw the first point
of a line.
About to draw the second
point of a line.
Tabular presentation
When you have finished drawing a regular line,
its object type, Id number, length, angle and style appear in the Objects
tab in the tabular area.
The data in the Layers & Objects tab is
unavailable for direct editing.
Switching modes: line to arc, arc to line
You can switch
from the mode of drawing a regular line to that of drawing a tangent arc,
and vice versa.
To draw a regular line
- Do any of the following:
- On the , click
Line
.
- On the Objects menu, point to Lines, and then click
Line.
- Press CTRL+D+L.
- (Optional) Snap the starting point of the line to another object
or point.
- Click where you want the line's starting point to be.
- (Optional) Snap the end point of the line — or the line itself
as an object — to another object or point.
NOTE: You can use all snapping modes except Concentric-to.
- Do any of the following:
- Click where you want the end point to be.
- In the contextual edit bar, enter values for L, Angle,
Dx and Dy, and then press ENTER or click in the graphical
area.
NOTE: When you are drawing a series of connected lines,
the end point of a line is the starting point of the next line. When you
point to an object, all its control points are highlighted, and you can
choose a point from which to draw the next line.
To modify a line by changing its attributes
- Select the line.
- In the contextual edit bar, modify the values, and then press ENTER.
To reposition a line by dragging
- Select the line.
- Do any of the following:
- Drag the line to where you want it to be, and then click.
- In the contextual edit bar, in Dx and Dy enter offset
distances relative to the line's original location, and then press
ENTER.
NOTE: If a line's control points coincide with the control
points of other objects — for example, when the line is part of a design
or is connected to another object — EngView repositions the line and modifies the connected objects according to the
direction and distance at which you drag the line.
