In addition to the arrowheads, I should be able to choose solid or broken line. If the broken line is selected the user would have the ability to change the segment (line) and gap (breaks) colors (could use foreground and background by default) and width of each. By adding width of the segment and gap, the user is able to control whether it appears as a dashed line (4px segment + 2px gap) or dotted line (1px segment x 1 px gap). You could add additional features for staggered gaps to produce interesting effects.
I would like to create geometric figures with just outlines and no fill in photoshop. And also be able to write in the exactly size of it. As it is now I have to make a vector figure in Illustrator and then import it in Photoshop. It would be more easy to do it in photoshop while I ́m already working there. Maybe in CS6? 🙂
Hate to bump this back up, but definitely want to support this notion. The process that @2306023 uses works as a great work around (for dotted lines), but if I want to create any sort of real dashed line, the process is a lot more upsetting (such as creating a brush pattern), or outright opening illustrator, which i'm lucky enough to have the luxury to do.
Real dashed line implementation would allow me to set the size of the dashed (the length of the dashes) at the very least, if not the full implementation similar to illustrator (where I can set up a dash/gap/dash/gap/dash/gap pattern).
This would be great under the individual brush settings next to scatter, and possibly an option under the stroke for blend modes.
That's definitely a very nice tip and a clever way to do it. But it would be wonderful if there was actual support for dashes like there is in Illustrator.
On the effects menu under Strokes.
You can create dashed strokes by increasing the Spacing on your Brush (under the Brush panel>Brush Tip Shape). If you increase the Spacing to about 200% (or whatever fits your needs), you can then stroke paths or selection marquees with a dashed (or dotted) line.
