Place Fixtures Matrix

Used to place a matrix of ceiling fixtures in any type of ceiling (linear, gypsum board, plaster, or lay-in for example). This tool is very useful when multiple rows and columns of fixtures, or an array of fixtures, need to be placed simultaneously. An outline of the fixture matrix dynamically displays prior to placement. You specify the number of matrix columns and rows and the distance between rows and columns for the array, prior to identifying the location.

SettingDescription
# Rows Sets the number of rows in the ceiling fixture matrix array.
# Columns Sets the number of columns in the ceiling fixture matrix array.
Row Spacing Sets the row spacing distance between ceiling fixture placement points in the matrix array rows.
Col Spacing Sets the column spacing distance between ceiling fixture placement points in the matrix array columns.
Offset Sets the ceiling fixture placement point offset mode for each fixture. The offset mode causes the placement point (controlled by the pointer) to change position. The offset does not change the position of the cell origin (which remains the same in every instance).
  • Top Left — Dynamically places the ceiling fixture to the top left of the placement point.
  • Top Center — Dynamically places the ceiling fixture to the top center of the placement point.
  • Top Right — Dynamically places the ceiling fixture to the top right of the placement point.
  • Center Left — Dynamically places the ceiling fixture to the center left of the placement point.
  • Center — Dynamically places the ceiling fixture centered upon the placement point.
  • Center Right — Dynamically places the ceiling fixture to the center right of the placement point.
  • Bottom Left — Dynamically places the ceiling fixture to the bottom left of the placement point.
  • Bottom Center — Dynamically places the ceiling fixture to the bottom center of the placement point.
  • Bottom Right — Dynamically places the ceiling fixture to the bottom right of the placement point.
Elevation Sets the ceiling fixture matrix elevation mode.
  • Space Height — Places the ceiling fixture matrix at the active space height elevation.
  • Active Depth — Places the ceiling fixture matrix at active depth elevation.
  • User Defined — Places the ceiling fixture matrix at a user defined elevation.
    • User Defined field – Enabled for User Defined Elevation mode is set to. Sets the User Defined Elevation value.
  • Active Floor/Reference Plane — Places the fixture on the active Floor Reference Plane/ACS, as defined in the Floor Selector.
