How do I draw a perfectly horizontal or vertical line?
NOTE: This video shows a slightly older user interface but the instructions are still accurate.
NOTE: This solution only works on iOS devices.
Scriptation currently does not have a Snap To grid to create perpendicular lines with the Shape Tools.
But - you can still do it! Here's how...
Use the Pen tool to create a tiny dot.

Tap + drag a corner of the bounding box to expand your dot left/right or up/down. Doing so will create a perfectly straight line!

TIP: Is your line somewhat curved? Temporarily toggle off Natural Drawing, and create a new dot.
With the line created, tap Inspector to adjust the style, color, opacity and thickness of your line. You can also tap Save to create a Saved Annotation.

Want to change your line's orientation? Adjust the line thickness and the bounding box to change directions.
