Can I design my project on a grid?
You can use grid columns in the background of your project to make laying out your elements easier.
Click the gear icon in the bottom toolbar and choose from the Columns submenu. You can choose among 12 columns, 16 columns, 24 columns, and having the grid hidden.
(Note that your grid settings are not saved with the project, so your collaborators may have different grid settings or the grid turned off entirely when viewing the same project.)
