Line

Draws a single line segment.

Steps:

1. Pick

   the start of the line.

2. Pick the end of the line.

3. Use object snaps to reference existing geometry.

Options

BothSides

Normal

Draws a line normal to a location on a surface.

1. Select

   a surface.

2. Pick

   the start of the line  on the surface.

3. Pick the end of the line or type a length, and press Enter

   .

Option

IgnoreTrims

No

Surface trims are taken into consideration and showing a no-access cursor

when the marker is off the visible part of the surface.

Yes

Surface trims are ignored. The no-access cursor

is shown when the marker misses the untrimmed surface.

Angled

Draws a line at a specified angle from a reference line.

1. Pick

   the start of a base (reference) line.

2. Pick the end of a base (reference) line.

3. Type the pivot angle and press Enter

   .

4. Pick the end of the line.

Vertical

Draws a line vertical to the construction plane.

1. Pick

   the start of the line.

2. Pick the end of  the line or type a length and press Enter

   .

FourPoint

Draws a line using two points to establish direction and two points to establish length.

1. Pick

   the start of the base line (reference location).

2. Pick the end of the base line (second reference location).

3. Pick the start of the line.

4. Pick the end of the line .

Bisector

Draws a line that bisects a specified angle.

1. Pick
   the start of the bisector line.

2. Pick the start of the angle to bisect.

3. Pick the end of the angle to bisect.

4. Pick the end of the line or type a length, and press Enter

   .

Perpendicular

Draws a line perpendicular to or from a curve.

1. Pick

   the start of the line on a curve.

2. Pick the end of  the line.

Options

Point

Allows you to pick
a point that is near, but not on a curve, overriding the built-in object snap.

FromFirstPoint

Forces the line to go through the first picked point on the curve instead of allowing the point to slide along the curve.

2Curves

The line will be perpendicular to two curves.

Tangent

Draws a line tangent from a curve.

1. Pick

   the start of the line on a curve.

2. Pick the end of the line.

Options

Point

Allows you to pick
a point that is near, but not on a curve, overriding the built-in object snap.

FromFirstPoint

Forces the line to go through the first picked point on the curve instead of allowing the point to slide along the curve.

2Curves

The line will be tangent to two curves.

Extension

Extends a curve with a line.

1. Select

   a curve (line) near the end you want to extend.

2. Pick the end of the line or type a distance and press Enter
   .

Lines

Draws multiple adjoining line segments.

Steps:

1. Pick

   the start of the first line segment.

2. Pick the ends of the segments.

3. When you have finished drawing lines, press Enter

   .

4. A series of unjoined, connected line segments are drawn.

Notes

Polyline

Draws a multi-segment polyline consisting of line or arc segments.

Steps:

1. Pick

   the start of the first segment.

2. Pick the next segment.

Mode

Controls whether line segments or arcs are drawn.

Line

Sets the drawing mode to line segments
.

Arc

Sets the drawing mode to arc segments
.

Direction

Center

Helpers

If Yes, turns on dynamic tracking tangent and ortho lines that make it easier to extend arcs with lines and draw arcs aligned x- and y-axes.

Length

Sets the length for the next line segment. This option is only available when the Mode option is set to Line.

Notes

• A polyline consists of line segments that are joined end to end.

• Use the Line
  command to create single-segment lines.

• Use the Lines
  command to create multiple touching line segments as separate objects.
