Then in the ruler tool Options bar click on the Straighten layer button to straighten the selected layer.Warning: two frame challenges in one answer!ġ) The guides are not moving at all - the visual precision is super-low when you are zoomed out: either zoom way in to place them precisely or use the View>New Guide menu approach so that you create them in exact places using numeric entry.Ģ) Photoshop is so deeply the wrong tool for your task that it's counter-productive to use it - I recognize that of course AutoCAD is expensive if you're not using it routinely - however there are so many CADD tools out there these days which are both excellent and either free or super-low cost that this entire exercise is moot.

Note that the ruler tool line only remains visible when the tool is selected (or you can hide it with the View Hide Extras command). Please go to Illustrator preferences > General > and select Show/Hide Rulers (refer attached screenshot). As you drag this out, the angle measurements are updated in the ruler tool options bar and Info panel. After drawing a measuring line, Option/Alt-click on one of the end points and drag out a second measuring line. The ruler tool also has a protractor mode. In the example shown here, I created a setting where 10 pixels equaled a 1 cm unit of length. This can be accessed by going to the Image menu and choosing Analysis Set Measurement Scale Custom… You can use this dialog to create a custom measurement scale setting where logical unit lengths can be given a name such as inches or pixels and you can set the pixel length for each unit of the logical scale.
