many people know that there is a “Parallel” osnap, but do you know how to use it?
Here’s how…

With the Parallel osnap turned on:

• Specify the starting point of the line
• Hover over the line that you want to be parallel to (reference line)
  • the parallel icon will stick to the reference line
• Move the cursor in the direction you want the new line to go
  • when your line is parallel , there will be a dotted line that appears
• Enter the length of the line or pick to specify the end of the line
