■ Single arrows ( ) display as shape handles in elevation and 3D views when movement is
constrained to a line, but the outside direction is unambiguous. For example, a massing shape with no
dimension constraints displays with single arrows. Single arrow controls on a selected wall in 3D views
can also be used to move the wall. Place the cursor over the control and press
TAB to change the control
from a shape handle that lengthens or shortens the wall to a drag control that moves the wall without
resizing it.
Drag controls on massing form
■ Double arrows ( ) display when the shape handles are constrained to move along a line. For
example, if you add a labeled dimension to a family and make it an instance parameter, it displays with
a double arrow after you load it into a project and select it.
TIP You can right-click the wall end controls and use an option on the shortcut menu to allow or disallow wall
joins.
Flip Controls
Click a flip control (double arrows) to change the orientation of an element. For example, when you flip a
compound wall, you reverse the order of its component layers. Doors with a swing have 2 flip controls: Flip
the Instance Facing (which controls whether the door swings in or out) and Flip the Instance Hand (which
controls whether the door swings right or left). Flip controls display only when practical.

TIP You can also flip a selected element by pressing the SPACEBAR.
Pushpin Controls
A pushpin is a user-placed control that provides a quick way to allow or prevent changes to an element’s
position. After you place a pushpin, you cannot move the element until you unpin it (by clicking the pushpin
control). When the element is unpinned, a red X displays on the control. After moving the element, you
