I hate to boast but i am pretty good at Google sketch up 8, and i decided to share some of my talent. so i amde a model airplane to be cut out with a laser cutter.
Step 1: Starting Off
i start with a 16" by 12" by 1/8" piece of balsa wood, that is the max size the will fit in the laser printer.
Step 2: Designing the Body
i decided to do a simple blocky body, using inches as markers for the corners. after i had it done i decided to round the corners a little , so it would look more natural.
Step 3: The Wing
i made the wing the same way i made the body using inches for intersection of where my lines go. and the back wing the same way.
Step 4: Finished Design
now your design is finished and you can go cut it with your epilog zing 16 laser. i would have a picture of the actual project but i am lacking a laser cutter. :(
