2.2.4 Reshape mode

Reshape mode is a general purpose object selection and edit mode. In this mode you can

• Drag an intersection rectangle to select those objects that intersect the rectangle
• Drag an intersection rectangle with the shift key to add those objects to the selection that intersect the rectangle
• Drag an intersection rectangle with the command key to remove those objects from the selection that intersect the rectangle
• Click on a deselected object to select it
• Click on an object with the shift key to add it to the selection
• Click on an object with the command key to remove it from the selection
• Click in empty space to deselect all objects
• Click on an object’s grip handle to reshape or resize it (as listed in the table)
• Click on an object’s outline, center blip, fill or on a hatch line to translate it
• Press the space bar to switch to Drag-scroll mode.

When translating, you can

• Choose as the target point for snaps the grip handle or center blip that is nearest to the cursor
• Hold down the shift key to restrict the translation to a horizontal or vertical movement
• Hold down the option key to use fast drags
• Press ESC to cancel the translation.

The cursor changes to an arrow cursor when it is on top of a grip handle. It is used for a reshape or resize, where you can

• Hold down the shift key during the drag to change the action (as listed in the table)
• Hold down the command key before the drag to change the action (as listed in the table)
• Hold down the option key to use fast drags
• Press ESC to cancel the reshape or resize.

Important
When you drag, you will notice that nothing happens until the cursor moves a few pixels. This is called drag hesitation and its purpose is to prevent unintentional drags caused by object selection.

Programming
Drags can be customized with CADSetDragPrefs, snaps with CADSetSnapPrefs.
