Every time I need a dashed line I have to create one from scratch and it really makes me mad, every time, that there is not a quick way to do this in Photoshop. Today, I found a way! Here is how to get a quick perfect dashed line every time you need it.
Open a new window and use the Rectangular Marquee Tool (M) to select a rectangle about as wide as you need your dashed line to be. Then screen capture this. It will capture the running ants selection rectangle showing a nice dashed line rectangle.
Open the new screen capture image in Photoshop. Go to Channels and R-Click on the RGB Channel so it selects the dashed rectangle.
Reverse the selection by going to Select > Inverse. Now use a brush to draw over the selection.
Hide the original layer and you should now have an isolated dashed-line rectangle. Select the part you need and paste it into your project.
You now have a quick way to create dashed lines when you need them.
Do you know a better or quicker way to do this? Please share in the comments.
