Using Surface Grids

Surface grids are used as guides to place objects or surfaces along the grid lines. Any surface can have grid lines, however the surface must have planar texture mapping to setup the grid lines. To set grid lines on a surface select 1 Surface A then use the Surface Grid: Set Surface Grid menu command to set the grid line size. The surface grid can be positioned and resized on the surface using texture transform. The grid lines rendered on the surface plane show the visible part of the grids that extend across the entire scene.

Note: To disable surface grid lines change the base map texture of the grid surface.

Surface Grid line color codes

● Bold blue lines are the Surface S vector direction planes.
● Bold yellow lines are the Surface T vector direction planes.
● Red lines are ½ the grid size
● Dark grey lines are ¼ the grid size

Aligning and Translating in Surface Grid Vector Directions and Increments

Objects and surfaces can be aligned and translated along the surface grid lines in ¼ grid distances by enabling grid align movements button on the control panel.  When in translate mode the ← →,↑↓ PgUp/PgDn keys and the x, y, z control panel keys correspond to surface S, N, T direction vectors. The grid surface needs to selected as Surface B and Solid A(s) or 1 Surface A needs to be selected to translate in grid increments.  Grid alignment uses Object centers or nearest surface vertex in case of Surface A.

Note: Selected Surface A takes precedence over Solid A(s) when both are selected for grid alignment.
