I have two line segments in an Adobe Illustrator file, line A and line B.
I would like to find point C, the point where if line A were to continue down along its path and line B were to continue to the left, they would meet.
What is the best way to do that in Illustrator?
Answer
You can either use Smart Guides, dragging your anchor to-and-fro for a moment to get the “line extension” Smart guide to show up, or you can draw your own guides, snapping to the existing geometry; either approach works, and where some designers prefer one method, some designers prefer the other.
See screenshot below for smart guides line extension snapping:
Ctrl+5 with segments selected converts those selected segments into custom guides – see screenshot below for custom guides.
