Пожалуйста, подскажите, кто знает, как перевести single drawing и multiple drawing.
Контекст:

An erection drawing is a single drawing (?) indicating the position and connection to one or more assembled parts in the construction. These drawings provide a general overview of the construction indicating the cohesion of individual assembled structural parts, including all details and information for proper erection.

The assembly drawings are a package of multiple drawings (?) indicating the cohesion of individual fabricated parts in a pre-assembled part of the construction.
Assembly drawings indicate the exact positions, dimension, material quality and welding details of individual parts in the (larger) assembled part of the construction.

Заранее спасибо
