What do we call a pictorial drawing that is not flat in the front , and is projected back on two axis?
Isometic
200
Which are more expensive to install and operate, passive or active gain systems? Why is this so?
Active systems are more expensive to install + operate bc they have moving parts, which are expensive to buy. They also require more maintenance than passive systems do
