To mirror more multiple objects, group the objects together and make the
group a child of the Symmetry object.
Construction Plane Object
The world grid is the default construction plane. The disadvantage of the world grid is that it cannot
be moved or rotated. When you create a construction plane, the world grid is switched off. The
construction plane (Objects > Modeling submenu) is an aid to object placement. You can place
objects, splines and points onto the construction plane. For example, you can move and rotate the
construction plane so that you can place tiles straight onto a slanted roof.
So that objects, points, surfaces etc. come to rest on the construction plane, activate the corresponding
options in the tool’s Snap Settings. For example, if you activate spline snapping and draw the spline in
the 3D viewport, it will be drawn straight onto the construction plane. Note that the mouse pointer
must remain below the horizon line in the process.

Type
The construction plane can be on the local XY, ZY or XZ plane.
Grid Spacing
Denes the distance between grid lines.
Lines
You can use this to set the number of grid lines in both directions. 100 is the default setting. Enter a
higher number if you need to increase the size of the construction plane.
Major Lines Every nth
Major lines are darker than normal lines. Use this setting to determine the frequency of major lines.
