How to create new guides from custom shapes in Photoshop tutorial
Guides are a useful feature of Photoshop for aligning layers as well as placing objects.
To show the guides in Photoshop, use the view menu and show and guides. Go to the show and you can select the guides to be on or off.
You can also use the view menu to clear guides as well as lock the guides (so avoid moving them by accident). You can also use the view to create a new guide as well as create a grid of guides.
To change the color of the guides, go to the preferences and guides and set the color to pink or green etc
You can find many custom shapes on the site such as Photoshop polygon regular custom shapes and polka dot / spots custom shapes and overlay custom shapes and texture designs for Photoshop
To use the new guides from the shapes, you can use custom shapes as well as rectangle shapes as well as ellipses etc but the key thing is that you are using the items as shapes.
It does not work with the path or pixel option. You can use the guide feature with a single shape as well as multiple custom shapes but the key thing is that the shape layers are selected.
1) Select the shapes you want (via the document or via the layers panel in Photoshop)
2) go to the view menu and the command (at the bottom of the menu)
3) select "New guides from shape" command.
The guides created will be based on the dimensions of the selected shape or shapes.
If you have an irregular looking shape such as a kettle then the guide will be drawn based on the left, right, top and bottom of the shape. If you have added a stroke to the custom shape then the stroke is also used for the dimensions so if you set a huge stroke, the result will be guides touching a long way from the original shape.
To create a quick set of guides, I generally don't use an unusual custom shape but they are fine but a rectangle shape is just as easy and you can use the alt / option to duplicate the rectangle and rapidly build up any number of guide lines, as you can use the new guides from shape command multiple times.
Select a single rectangle shape or custom shape
2) view and new guides from shape command
3) move the shape
4) repeat the new guides command and you will get an additional set of guide lines.
All kinds of complex designs can be created (sadly the guide lines cannot be turned into paths or shapes themselves though that feature is available in Illustrator, just not Photoshop)
Once you have the guides from the new guides command, you can then use them to snap layers etc to the guides etc as well as just aid in the construction of a design (use the snap to command in view menu and guides).
You can also just click on to them and move the Photoshop guides manually though that defuncts the actual relationship to the original shape. It should also be noted that there are artboard guides as well (to totally confuse)
