# Autodesk Inventor 2011 – Line Command

Autodesk Inventor 2011 | Line Command

Line Definition : A **line segment**** **is a part of a line that is bounded by two distinct end points and contains every point on the line between its end points. Depending on how the line segment is defined, either of the two end points may or may not be part of the line segment. Two or more line segments may have some of the same relationships as lines, such as being parallel, intersecting, or skew.

A Line has an equation of the form

y = mx+c

where:

*m*is the slope of the line.*c*is the y-intercept of the line.*x*is the independent variable of the function*y*.

Autodesk Inventor 2011 has some new functionality being added in sketching.

To activate the Line Command in Inventor, you can either press L from keyboard (as shortcut), alternatively you can click on the line command from

Sketch Ribbon Bar > Draw Tab > Line Command

As you activate the line command, you will be prompted to enter the X and Y coordinates of the start point of the line followed by the second coordinate in terms of distance and angle.

The advantage of creating lines with dimension, helps in constraining the line and increases productivity. This also gives way to making the sketch parametric.

The Line can also be drawn perpendicular | Parallel | Horizontal | Vertical to a previously drawn line

Line can also be started from Point Snap > Mid Point | Intersection | Center as shown below

Line can be created using different coordinate types

- Absolute Coordinate
- Relative Coordinate
- Polar Coordinate
- Cartesian Coordinate
