How should a CAD designer update a rectangular array to reposition the upper-right hole in a gasket design?

1. Use the MOVE command

2. Use the REFEDIT command

3. Use the ERACE command

4. Use the ERASE command

The correct answer is: Use the ERASE command

In this scenario, the adjustment to a rectangular array for repositioning a specific hole requires understanding of how arrays function within AutoCAD. A rectangular array creates multiple copies of an object arranged in a grid pattern. To reposition an individual object within that array, you generally should not erase and recreate the array. Instead, using the MOVE command is the most suitable option, as it allows for the repositioning of existing objects, which includes objects within an array. The MOVE command can directly manipulate the position of the upper-right hole without the need to erase it, thus preserving the integrity of the array setup and avoiding unnecessary rework. The REFEDIT command is used to edit a reference or an external block, which is not relevant for simply moving an object in an array. The ERACE and ERASE commands are intended for removing objects rather than repositioning them, which does not fulfill the need for updating the position of the hole in this case.
