Solid Modeling
It may seem like being able to create solid models efficiently and effectively
would be more appropriate for disciplines such as architecture and structural
engineering. However, with these skills, you can create the types of
components needed to convey your design accurately. MEP families such as
pumps, condensers, valves, and even lighting fixtures can have very complex
shapes or structures, and knowing how to create these objects with a
minimum amount of effort is key to being productive while remaining
accurate with your design.
Although MEP components are often complex, it is important to keep your
families as simple as possible while still making them recognizable and
useful. This does not mean that all of your objects should be boxes and
cylinders, but it also does not mean that you should be modeling the rivets,
screws, handles, and hinges either. As a general rule of thumb, if you can see
somethingatascaleof1/8″=1′-0″(1:100),thenmodelit;treatanythingelse
as detailing. Of course, this is not a hard-and-fast rule, but as you become
more proficient with the software, you will find a balance that works best for
your workflow.
Knowing how to create solid model objects that are accurate to the specified
components is as important as making them recognizable. Allowing for
parametric changes will make your families universally applicable to your
projects and design standards.
In this chapter, you will learn to do the following:
• Model solids and voids
• Orient geometry by using reference planes and lines
• Ensure the parametric change capability of models
• Determine optimal visibility settings for solids
• Create in-place Mass objects for analysis and documentation
