To apply a straightness control to a surface, the FCF is placed in the view where the controlled surface elements appear as lines. The FCF may point to the surface. The FCF’s shown below apply a straightness tolerance to the entire surface. The surface elements must, independently, lie between two parallel lines that 0.1 mm apart.

Use shielding and careful aiming to target the direction of the light beam so that it points downward and does not spill beyond where it is needed.

Light pollution is the human-made alteration of outdoor light levels from those ocurring naturally. It has harmful effects on:

Light where you need it, when you need it, in the amount needed, and no more. If light is deemed useful and necessary, follow these guidelines to prevent, or when that’s not possible, minimize light pollution.

Consider the surfaces of the cylinders shown. Which cylindrical surfaces are straight? In reality, no cylindrical surface is perfectly straight. How would we know if the cylindrical surface on the bottom is straight enough?

Use the lowest light level required. Be mindful of surface conditions, as some surfaces may reflect more light into the night sky than intended.

Straightness Control: Perfect straightness occurs when all points of an element lie on the same line. Straightness is a form control. The straightness control (u) defines how much each surface line element in a particular direction on a real part may vary from an ideal straight line.

Feature Control Frame: To control the straightness of a surface, a feature control frame (FCF) is used to apply the tolerance to the desired surface.

Tolerance Zone: The straightness tolerance zone is the area between two parallel lines. The distance between the parallel lines is the value of the straightness control tolerance. Each line element of the surface must, independently, lie within the area defined by the tolerance zone. The straightness tolerance does not control how cylindrical the part is.

We're going to go over some ways to use practical lighting the right way to still give off a cinematic look.

Too often, outdoor electric lighting installations at night are overlit, left on when not needed, and harmful to the environment. As a result, light pollution is a growing global issue that can negatively affect our environment and impact our quality of life. DarkSky and the Illuminating Engineering Society jointly published the Five Principles for Responsible Outdoor Lighting to prevent and reduce light pollution through the proper application of quality outdoor electric lighting.

By applying these principles, properly designed electric lighting at night can be beautiful, healthy, and functional. Projects that incorporate these principles will save energy and money, reduce light pollution, and minimize wildlife disruption.

All light should have a clear purpose. Consider how the use of light will impact the area, including wildlife and their habitats.

The straightness tolerance may be used to control the straightness of a planar surface, a cylindrical surface, a center plane or a centerline. When controlling a cylindrical surface, the straightness control (u) defines how much each surface line element may deviate from a perfectly straight line.
