Adding Breaks, when Creating Projections and Drawing Views

Automenu of projections and drawing views creation commands contains following options:

This option switches the 2D Projection command into the breaks editing mode. In this mode a click within the drawing window adds a break to the current projection. The type of such break depends on the direction of mouse movement at the moment right after clicking (horizontal movement adds a vertical break, vertical movement adds a horizontal break). After the first click , the manipulator of break boundary starts following the cursor movement, while the cursor itself changes the appearance to or  depending on the break type. Move the manipulator to the desired position and click again. The position of the first boundary will be fixed, and the manipulator of the second boundary will start following the cursor. Move the manipulator to the desired position and click once more. The position of the second boundary will be fixed, and the break will be complete. Next you can add more breaks in the same manner. You can use the object snapping for selecting a point, while moving a manipulator of break boundary. Snapping a manipulator to a point creates an associative link between a position of a break boundary and position of a point, i.e. upon future changes in a position of a point, a position of a break boundary will be updated accordingly.

 

Breaks manipulators may have different colors depending on condition of a break:

1 - Break base point marker is blue;

2, 3 - Breaks with no issues are green;

4, 5 - Breaks intersecting with other breaks of the same type are red;

6 - Breaks, that can not be constructed for some reason, are gray.

Active break, as well as inactive break under the cursor,
are displayed in more bright versions of corresponding colors and have thicker boundaries.

 

Colors of manipulators can be customized in system options (Options > Colors > Drawing Views with Breaks).

Intersections between breaks of the same type are ill-advised, due to extending time of recalculating the projection, but do not prevent the construction of a break.

Parameters of all added breaks are displayed in the Breaks tab of the parameters window. For the 2D Projection command this tab unfolds automatically upon calling the breaks adding automenu option. For the Drawing View command the breaks adding automenu option is available only, when view already contains graphic lines. In such case, the option launches the Edit Breaks command and opens the selected page. Then, upon finishing the breaks editing, the system returns to the creation of the view on the initial page.

A break is considered "active", when it is selected in the list of breaks in the Breaks tab. In order to edit break boundaries, move the cursor over the manipulator of the desired boundary and click. The break will become active, and the selected boundary will start following the cursor. Establish the new position of the boundary and click again to confirm the changes. Positions of breaks boundaries correspond to the Start and End parameters located in the Breaks tab. You can reposition boundaries by typing in new values of these parameters instead of using the manipulators.

The detailed information on the content of the Breaks tab is available in the Parameters of Breaks paragraph.

The break base point marker indicates the position of the breaks alignment center. By default, the center of projection/view is used as base point. The Edit Breaks command provides the custom base point selection option. Arrow of the marker indicates the breaks slope angle. At zero angle the arrow is pointed to the right horizontally.

 

Adds a vertical break with default boundaries positions. Default positions set value of the Start parameter to 40 and the End parameter - to 60 in units defined by the Measure parameter.

Adds a horizontal break with default boundaries positions similar to the previous option.

Allows applying the breaks of another projection to the current one, if there is a projection link between these projections. The option contains the drop-down list of all projections linked with the current one. Click and hold on the option's icon to invoke the list; then select a desired projection in the list. Breaks of the selected projection (if there are any) will be applied to the current projection. A short click on the option's icon copies breaks from the main view without invoking the list. Copying doesn't create an associative link between breaks of involved projections, i.e. future changes in breaks of the source projection do not affect breaks of the current one.

Breaks are either horizontal or vertical by default. This option allow to make them sloped. Activate the option, then click and hold , while moving the cursor around the base point. Breaks manipulators, arrow of base point marker and projection's bounding box will rotate following the cursor movement. The counterclockwise direction is considered positive. During rotation the bounding box will be re-sized in order to fit the whole projection. Set the desired angle of rotation and release . The angle value is displayed in the Angle input box in the Breaks tab of the parameters window. Alternatively, you can set an angle by typing in the value into the input box.
