Use drawing helpers to align objects
Do a right-click on the canvas. In the "view" menu there are 2 helpers for element alignment.

It is strongly recommended to use at least one of these helpers at the beginning of your project because a proper drawing will increase the quality of your final documentation.
Grid
The "grid" option allow a automatic align over the dotted grid show on the background of the canevas.

Rulers
the “Rulers” option shows vertical and horizontal ruler frames at the border of the canvas. Click on the frame to place a guide. Align all objects at the guide. When you move an object over the guide the guide will change to red to indicate that the shape of the object is aligned with the guide.
