How do you do the engineer glitch in command and conquer 3 tiberium wars?

At the start build a CRANE then build a power plant in the crane and a REFINERY in the COMMAND CENTER, when the POWER PLANT is built, drop it down then build a BARRACKS and build an ENGINEER from it. When the REFINERY is built drop it down and build a COMMAND POST. When it is built drop it down. Build POWER PLANTS in both COMMAND CENTER and CRANE, and use the radar to see over the enemy base, use the ENGINEER to capture an enemy building, before it goes out of the build radius drop both POWER PLANTS on top of the ENGINEER and the ENGINEER will disappear and capture the enemy building auto-matically.
