Simulation»Grid (Ctrl Alt G)

Activates the Grid dialog, which defines the boundaries and appearance of the world. The Reset button resets the grid appearance and size to reasonable values.

Grid Units can be set to any convenient value and need not match the units used when the model was created. For optimal display and control, the Min/Max grid value dimensions should exceed the dimensions of the model itself. The Grid subdivision size defines the spacing of the grid for visual clarity only (excessively small spacing can greatly increase the CPU requirements during scene rendering). The Snap to grid checkbox and associated input field define a rounding factor that can optionally be used when interactively constructing objects using the mouse pointer.

Select Grid color to set the color of the grid lines (the background color is set in the Simulation»Options dialog Misc tab).

The main axis (model origin), grid contour boundary and grid subdivision lines can all be toggled visible or invisible using the Display Show checkboxes.

The coordinate frame marker size, color and style can also be controlled from the Grid dialog. Three horizontal sliders control the size of the arrow. Colors for each axis of the marker can be set in the Colors area. The arrow style can be set using the Arrow type selection.
