Add Line

Geometry toolbar


Left-side of the graphics-area


Add menu > Geometry sub-menu> > Add Line

What to do:

1.Edit a Part
2.Click Add Line in the Geometry toolbar.
3.Drag in the graphic-area to specify the Line's start-Point and then its end-Point.

'Drag': mouse-button-down [start-Point], move your mouse-pointer, mouse-button-up [end-Point].

The Line is now in the graphic-area.

There are two ways to add the start-Point and end-Point of the Line.

As you 'mouse-button-down' or 'mouse-button-up':

Add the start-Point or end-Point, or both, as 'Free Points'

Add constraints and dimensions to the start and end-Points later [which you can also delete, if necessary] to position a joint, or for other construction geometry.

Merge the Points with different-Points

Do this to construct a 'sketch-path', for example.

See: Hover+Drag , merge-points.

More details

1.A Line (and a CAD-Line) has an Origin and a positive X–axis direction.
The Origin is its start-Point.
The positive X–axis is from the Origin to its end-Point.
2.Use the Origin and X–axis direction of the Line to:
Give the positive direction of a Slider. See Add Motion-Dimension FB
Give the Origin and +X–axis of a Plane. See Add Plane

To identify which is the Line's start-Point and/or end-Point when it is constrained to other Points.

If the Line is coincident with other Points, then do:


1.Click on the Line so that it shows in the Selection-Window
2.Right-click the Line in the Selection-Window
3.Click 'Show element references...' in the contextual-menu

Take a note of the Point numbers in the dialog. The lowest Point number is the start-Point and Origin of the Line.


1.Click the Line's two Points in the graphic-area

The Point with the lowest Point number, as noted in STEP 1, is the start-Point of the Line.
