Rotating and mirroring artwork

Lesson guide

1. Open arrow-start.lzrproj and select the arrow outline. Notice the notch on its top edge.
2. Try a curved rotation handle just outside a selection corner. Undo with Cmd + Z on Mac or Ctrl + Z on Windows/Linux.
3. Enter 90 in the degrees field in Properties and apply with Enter or Return. The arrow points down. Enter 0 to restore the starting direction.
4. Click Flip Horizontal: it points left, with the notch still on top. Undo, then use Flip Vertical: it points right, with the notch underneath.

Clear the selection and compare the final demonstration with arrow-complete.lzrproj.

Independent practice

Reopen arrow-start.lzrproj. Enter 90 degrees, apply it, then click Flip Horizontal. Do both actions in that order.

• Which direction should the arrowhead point?
• Where should the notch be?

• Start from the original arrow, not the already-flipped demonstration answer.
• Inspect the outline after clearing the selection.
• Save your own copy and compare with arrow-practice-check.lzrproj.

Explained answer

Arrowhead down, notch on the left

That is the result of the 90-degree turn followed by Flip Horizontal. The notch makes the mirror visible.

The footprint changes orientation

The starter occupies 70 × 40 mm. A quarter-turn occupies 40 × 70 mm. Turning it does not stretch the underlying arrow.

• arrow-start.lzrproj

  One unlocked, right-pointing notched vector. Use for the demonstration and your attempt.

• arrow-complete.lzrproj

  Demonstration answer after Flip Vertical. Points right with the notch below.

• arrow-practice-check.lzrproj

  Independent answer after 90 degrees and Flip Horizontal. Points down with the notch left.

If the result differs, return to the starter and apply the two actions again. A symmetrical shape can hide a flip, so use the notch to check this arrow.
