ARRAYS

Some key points:

• Add modifier (Array)
• Constant offset = Object dup position on grid, Relative offset = position relative to object
• Fixed count = number of copies
• = Transform properties (Edit Mode)
• Attach empty object to array
• Click merge tab = attach where touching
• Object offset = control entire array with an object in these cases I just used an empty
• There is also a merge option in the specials menu (Edit Mode) this is a useful menu.
• If your model ever looks a bit odd you can remove doubles in special menu and press + to re-calculate normals, this often helps quite a lot.
• Ctrl + P = (Make parent) This is useful when you want one object to be a parent of another (be affected in the same way)
• When using object offset make sure the two objects have the same scale and roation arc on their transform properties
