Porch / Deck Stairs (Configurable)

grabcad

This is a fully automated (configurable / customizable) multibody part file. All you have to do is open it (in SolidWorks 2014 or later), and then start modifying the overall dimensions to fit your personal project. The equations within SolidWorks will do the rest. I've also included an attached drawing file that includes a complete cut list and individual detail views. I've also attached comments to the features, so use SolidWorks' Part Reviewer (available from 'Tools" drop-down menu) to review my explanations of how and why I modeled this part the way I did. Also, make sure to check out my "Lumber Weldment Profile Library" on GrabCAD to easily create models like this one out of standard 2x4's, 2x12's, etc.
