The Break Screen Function

The Break Screen function separates an entity at, or perpendicular to,an arbitrary location.To perform the function, you select geometry inthe graphics area and click the break location.

To open Break Screen:

  • In the Break group, of the Utilities ribbon, click Break Screen.

The Parameters open in the Data Entry Manager.

The Data Entry Parameters

Break Option

Entity Selection

Selected Geometry


(Delete) - removes the highlighted item from the list.

The list box will list the entity currently selected for the function.

  • OK - finalizes the function.

  • Cancel - exits the function.

Quick Steps - Break Screen

  1. Open the function.

    The Selected Geometry list automatically has focus.

  2. Select the entity to be broken.

    A preview of an X appears on the entity.

  3. Move your mouse in the graphics area, and notice the X tracks your mouse as a perpendicular point on the entity.

  4. Put the X in the desired place on the entity and click once.

  5. The entity is broken at the location of the X.

  6. Repeat as necessary.

  7. Click Cancel to close the function.


The Break Screen function is used to break a wireframe entity perpendicularto the location at which you click in the graphics area.This functioncan be used with any wireframe entity in the graphics area.You firstselect the entity to break, and then you click any location (that is ata right angle to the entity) to break it.(For help drawing wireframeentities, view the CAD_Tutorials.)

With any wireframe geometry (lines, arcs, or splines) in the graphicsarea, use the following steps.

  1. In the Break group, of the Utilities ribbon, click Break Screen.

The Break Screen parametersdisplay in the Data Entry Manager.

  1. In the graphics area, highlight the entity you would like to break, and select it.

Notice that the entire entity is displayedin the Highlight color.This shows that the line is a single entity.

Also, notice the preview of the breaking point displays immediately after the entity is select.

  1. Move your mouse away from the selected line, and notice the break point follows your mouse.

  2. To break the entity, click any locationin the graphics area that is perpendicular to the entity.

After clicking in the graphics area, theentity is broken perpendicular to the point that you click.Notice thatthe entity is no longer displayed in the Selection color.

  1. To visually confirm the change, pointto either end of the broken entity.

Notice that only half of the line is displayedin the Highlight color.

You can repeat the process explained in thisexample to break as many entities or break one entity as many timesas you want.Be aware that after selecting the entity to break, if youclick anywhere in the graphics area that is not perpendicular to thatentity, you will receive a Failed In: Break Screen message.

  1. To end the function, in the Data EntryManager, click Cancel.

This concludes the example.
