Found this silly UI hack that leverages CSS to help in drawing straight lines. Yeah, there's probably a much cooler .js way to do this, but whatever.
So, you ever notice when you're using Rectangles to draw lines that they're a pain in the nethers? First you set the height to 1:
Then when you go to make it longer or shorter, you end up always resizing it's height accidentally. This would be bad:
Plus of course rotating it is a pain because it takes several adjustments to get it right:
And finally, they're notoriously difficult to select in the UI's viewer.
Instead, try the following to make working with straight lines easier:
A. Make the height of the rectangle much thicker than you'd normally want it:
B. Drop the Border Width to 0:
C. Set the Fill Style to None
D. Now grab the top edge and set it's width to 1:
E. Set the Origin to 0, 0:
F. Now it's easy to position on one element and resize and orient it to reach your desired length and angle:
G. You can then added dotted styles to it:
And of course it's easier to grab. Maybe I've been missing something simple this whole time, but this is what I end up doing ;p
