Whereas in a conventional hand drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2D CAD system allows a copy of the original to be modified, saving considerable time. 2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide ...

[1] [2] There are newer glass blocks injected with argon gas and having a layer of low-emissivity glass between the halves, which increases the insulative (U) value to 1.5 W/m 2 ·K, which is between triple glazed windows (1.8 W/m 2 ·K) and specialty double glazed windows with advanced frame and coatings(1.2 W/m 2 ·K).
