Circle of Light
Catherine is working on a project that has a rotunda and requires
lighting that follows the curve of the walls. Knowing that many changes
will occur before the final decision is made on this high-profile area, she
creates a lighting fixture that represents a custom linear LED strip. She
creates a sweep with an arced path, provides a parameter to control the
length of the arc by adjusting its angle, and provides a parameter for
the length of its radius. As her architect works with the client to finalize
the design, Catherine can easily keep up with the changes by editing
parameters instead of having to re-create the fixture each time the
model changes.
Visibility Control
The visibility parameters of solid geometry provide useful means for
controlling the behavior of solids in a family that is used in a project. For
many MEP discipline families, the actual solid geometry is not shown in
plan views, but instead a symbol is used. This is especially true for electrical
devices and even some light fixtures.
If you are concerned about file performance, it is a good practice to limit
the visibility of solid geometry to only the types of views in which it needs
to be seen. Symbolic or model lines can be used to represent the geometry
in views where the solid does not have to be shown, such as plan views
or reflected ceiling plans. Setting the visibility of solid geometry to appear
in 3D views, sections, and elevations is important because it helps keep
your project coordinated by allowing you to locate items when a section or
elevation view is created, without having to draw additional linework in the
section or elevation view.
In some cases, you may also want to control the visibility of solid geometry
based on the detail-level setting of a view. For example, you may set the
