Creating a Breakout View

This task will show you how to create a breakout view. In other words, you will remove locally material from a generated view in order to visualize the remaining visible internal part. A breakout view is one not in direct projection from the view containing the cutting profile. In other words, it is not positioned in agreement with the standard arrangement of views. A breakout view is often a partial section.

Before You Begin, make sure you customized the following settings:

Grid:
De-activate the Grid icon from the Tools toolbar (bottom right).

In addition: Make sure the generated view is active. In this particular case, double-click the left view.

Open the GenDrafting_part.CATDrawing document.

Click the Drawing window, and click the Breakout View icon

from the Views toolbar (Break View subtoolbar).

Click the first point of the breakout profile.

Click as many points as desired for creating the profile.

If needed, double-click to end the profile creation and automatically close this profile.

Click on the profile first point to close and end the profile creation.

The 3D Viewer window appears and presents the 3D part corresponding to the generated view. This window allows:

	positioning the 3D part according to a view you go over (on the drawing), provided the Animate option is checked.
	visualizing view planes that correspond to some kind of a prism that allows you breaking the view. One plane is fixed and green dashed. The other can be moved either by dragging it to the desired location or by going over the circle or the edge of a perpendicular view (in this task, go over the front view that is perpendicular to the left view). This modifiable plane is plain and green.

Check the Animate option for visualizing the 3D part in accordance with the position of the cursor on a generated view.

In the CATDrawing document, go over the front view that is perpendicular to the left view.

In the CATDrawing document, go over and then select the edge or circle to be used as one extremity plane.

The modified plane is orange until you select it on the generated view.

In the 3D Viewer window, drag the plane that can be moved to the desired location.

Click OK in the 3D Viewer window.

The breakout view is created.

You can create a breakout view on a view that already contains breakout views.

	Once created, the breakout view profile cannot be modified.
	The geometry that defines the breakout view is not associative with the generated views.
	You cannot apply a breakout view and a broken view command to the same view.

You can generate the following types of views from a breakout view:

	projection views,
	auxiliary views,

	section views
	section cuts.

Once the breakout view is created, you can right-click the view, and select the Remove Breakout option.
You can also right-click the view, select the Apply Breakout To option and click another view you want to apply the breakout to.

To generate views (projection, auxiliary, section and section cut) with this breakout, go to Tools -> Options -> Mechanical Design -> Drafting from the menu bar, click on the Layout tab, and activate the Propagation of broken and breakout specification option.

Propagating a specification means generating a view (B) from another view (A) on which you previously performed an operation and including this operation in the generated view (B).

For example, (i) you create a breakout view (view A) and activate the activate the Propagation of broken and breakout specification option, you then (ii) generate a projection view (view B). As a result, the projected view (view B) will display this breakout area.

You can choose the line type you want to assign to the breakout view. To do this, go to Tools -> Options -> Mechanical Design -> Drafting , click on the Generation tab, click the Linetype switch button and select the desired line type from the Linetype for some views dialog box.
