Try it: Garden trellis panel with a name-plate area

A 175 x 255 mm plywood trellis for a climbing plant, with a solid patch in the middle for a plant name plate. Build a full grid of openings, then ERASE the four in the middle.

  1. Frame: REC, 0,0, @175,255, Esc. First opening: REC, 15,15, @30,30, Esc.
  2. Click the opening and type ARRAYRECT 4 40 0. You get a row of 4.
  3. Drag a window around the 4 openings and type ARRAYRECT 6 0 40. You now have 24 openings.
  4. Drag a window from about 50,90 to 130,170 so it holds the four middle openings (rows 3 and 4, columns 2 and 3). Type E and press Enter. The result reads Erased.
  5. Screw holes for the name plate: C, 65,130, 2.5, Esc, and C, 115,130, 2.5, Esc.

Challenge: Erase one more opening by mistake, then type OOPS. It comes back, and your screw holes stay where they are (UNDO would have removed them first).
