Use the below $2-$D piping drawing to create an isometric drawing of the hot water piping for a sink room on an isometric grid and perform a quantity take off. The room will have four sinks and a water heater as shown. The scale for the pipe is $1$ block $=1$ foot of pipe. The pipe runs will travel through the ceiling and drop down to the water heater and sinks$.$ All pipe drops will be $6$ feet. The pipe drops to the sinks will run inside a cabinet for $2$ feet and then back up $1$ foot to the sink. You can only acquire piping in $10$ foot sections. Any straight pipe runs longer than $10$ feet will require a tee or coupling.

$1.$ Draw the layout below in isometric view.

$2.$ Find the quantities of materials needed to assemble the piping.
