Figure 17.20 Reference line and its planes
Reference lines can be dimensioned when a family is placed into a project,
and they also have a parameter that allows you to set them as a strong or
weak reference or not as a reference at all. You cannot use reference lines to
define the origin of a family.
Solid geometry can be aligned to reference lines in the same way they
are aligned to reference planes. Using reference lines and planes is the
most effective way to create parametric behavior of solid geometry within a
family.
Mastering the tools for creating solid geometry will make content creation
an efficient part of your Revit MEP 2015 implementation. Practice creating
different types of solids by completing the following exercise:
1. Open the Ch17_Solid Geometry.rfa file found at www.sybex.com/
go/masteringrevitmep2015 .
2. Click the Extrusion button on the Forms panel of the Home tab. Select
the Circumscribed Polygon drawing tool from the Draw panel. See
Figure 17.21 .
