1. Go to the Modify tab and select Align tool (Modify panel) 
or use shortcut keys AL.
2. Select the reference element (click on the line or side of the element you wish to align the element to) and then click on the side of your element you wish to align. You can also:
- align multiple elements: press CTRL while selecting multiple elements to align.
- use Lock to apply a constraint between the elements as they are aligned. When a constrained element is moved, the other will be moved with it maintaining the constraint alignment.
- Select how patterns applied to surface will behave when aligned. Patterns can be aligned across the entire surface, or each face of an element can have a separate pattern alignment.
Example: Align the ends or centers of walls or beams with selected beams, lines, or walls, adjusting window heights, and joining endpoints of walls with a selected line.
You can find more information about Align tool here.
Note: Before selecting the side of the element, you wish to align (to), move the cursor over the element until the side of the element gets highlighted. Then click it.
3. You can control constraints of the element by using the padlock. Locking the padlock will make reference element (if you later move it) aligned with selected element. Note: I the padlock symbol disappears (is no longer displayed because you have done something else) click Modify and select the reference element to make the symbol redisplay.
4. Press ESC once, to start a new alignment.
