Add pattern blocks to this design so that your final object has:[br][br]1. Rotational symmetry but no reflection symmetry[br]2. Rotational symmetry with no reflection symmetry different from 1 (if possible)[br]3. Reflection symmetry[br]4. Reflection symmetry with a line different from 3[br]5. Reflection symmetry with two lines[br]6. Both reflection and rotational symmetry[br][br]Use Copy/Paste from the Sandwich Menu > Edit to make copies of the shapes as needed.
