Hello! I would really need some help figuring out the following:

Question: What is the most effective way to create even spacing between blocks or lines?

Bonus question: Is there a way to align blocks / lines so that they would "snap" to the same vertical or horizontal line?

Currently I make a certain length line, and use that as a "measuring stick" between two blocks or lines, and also use lines to align objects and other lines, but this is very ineffective. Is there any way to create even spacing / alignment between objects?
