Geometry | CAD-Line

Why use Add CAD-Line?

There is a CAD-Line from the start-Point to the end-Point of each Part you add to the model.

Use a CAD-Lines to:

Import DXF Drawings


Import STL File

Specify Mass & Inertia Properties

You can also do Add CAD-Line to add more CAD-Lines. Then you can import more CAD files onto one Part.

Add CAD-Line

Geometry toolbar

Toolbar :

Part-Editor : Geometry toolbar

Menu :

Part-Editor : Add menu > Geometry sub-menu> > Add CAD-Line

To Add :

1.Part-Editor: Click Geometry toolbar > Add CAD-Line

2.Part-Editor: Drag in the graphic-area to specify the start-Point and then its end-Point.

Drag: mouse-button-down (start-Point), move your mouse-pointer, mouse-button-up (end-Point).

The CAD-Line is now in the graphic-area.

To Edit :

See CAD-Line dialog-box


Add with Free-Points* to locate a joint or add as a layout-sketch.

Do NOT HOVER above a Point* before you mouse-button-down or mouse-button-up.

Add with Merged-Points* to construct a sketch-path or sketch-loop

Do HOVER above a Point* before you mouse-button-down or mouse-button-up.

See: Hover+Drag , merge-points.

Point* : start-Point, end-Point, center-Point.

CAD-Lines in an Added-Part

CAD-Lines in an Added-Part

In the Graphic-Area:

CAD-Lines are GreenRed-14-1b (default color)

CAD-Lines have a Coordinate System:

+X–axis: from its start-PointRed-14-3 to its end-PointRed-14-4

+Y–axis: at +90º from the +X–axis

+Z-axis: perpendicular to the Mechanism Plane (towards you in the default view (Front-View))

The Coordinate System is important to orientate the CAD files that you import.


In the Assembly-Tree:

CAD-Lines are the only sketch-elements that show in the Assembly-Tree.


Note :

You can open the CAD-Line dialog-box from the:




Model-Editor (when there is a Solid linked to the CAD-Line)






Drag from the start-Point to the end-Point of CAD-Line


The CAD-Line shows in the Assembly-Tree.
