Requesting reflected ceiling plans and elevations is essential for selecting the appropriate lens for a front projection system because these drawings provide crucial information about the layout and dimensions of the space where the projection will take place.

Reflected ceiling plans show the location of the projector relative to the screen and account for ceiling heights, potential obstructions, and the positioning of other fixtures that might impact projection quality. Elevations provide a vertical view of the space, offering insight into how the projector’s throw distance and angle of projection will relate to the screen's location. This information is vital for determining the lens specifications, such as throw ratio, which influences how far the projector must be from the screen to achieve the desired image size and focus.

In contrast, while building sections, millwork details, floor plans, wall details, and structural or electrical plans may provide valuable information about the environment, they do not specifically address the critical aspects of projector placement and screen location needed to choose the correct lens effectively.
