Build Lock And Nudge

Lock a build preview in place, then nudge it into position.

Hold the Build Mode: Toggle key to enter Enhanced Build Mode; its default is H held for half a second. With a valid build preview selected, tap the Hold Placement key to lock it. The direction keys move the locked preview by 1 metre, or by 0.25 metre and 0.10 metre with the small and tiny nudge modifiers. The defaults are arrow keys plus Page Up/Down, Ctrl for small nudges, and Shift for tiny nudges. Hold Confirm to build; placement range, materials and normal placement restrictions still apply. The helper panel shows your current bindings.

You can change the nudge distance in Configurations.
