metric A standard of measurement that is based on the meter.
When you install Revit Architecture, you specify whether you want to use imperial units (feet and inches)
or metric units (meters and centimeters). You can also change the type of units used in a project. See Project
Units on page 502.
mirror To reverse the position of a selected model element, using a line as the mirror axis.
For example, if you mirror a wall on a reference plane, the wall flips opposite the original wall. You can pick
the mirror axis or draw a temporary axis. Use the Mirror tool to flip a selected element, or to make a copy
of an element and reverse its position in one step.
The following image shows the results of mirroring and copying a door, using the center wall as the mirror
axis. See Mirroring Elements on page 380.
miter A joint at a 45-degree angle, or evenly angled between the joined elements. Mitering can apply to
walls, wall sweeps, railings, structural floors, roof fascia, curtain wall mullions, and other model elements.
When 2 walls join, you can edit the wall join using a miter joint or other joint styles. See Editing Wall Joins
on page 653.
