Dynamic Component - Stairs

AndriyG81

Hello everyone. It is been some time since my last post. Here is goes:

Back in school, when I was working on concept models for my projects I always wanted to have a Staircase Tool. Sadly, SketchUp did not have one. There were various ruby scripts that would draw some great looking stairs. However, in my opinion, they all had one big flaw. You had to know exactly dimensions of your stairs. While I was “sketching” first ideas, I would move things around, make constant changes. Every change would mean I had to delete my old staircase, punch in new numbers in a ruby script and get a new staircase. I thought how great it would be to be able just grab a “scale tool”, drag it on a screen, and reshape my stairs.
Finally, Google introduced Dynamic Components. I figured it would be a perfect solution. What you see here is a result of my “attempt to learn” dynamic components. This simple dynamic stairs can be scaled and as you scale them, stair will snap to the closes dimension to satisfy riser-tread proportion. You can also “interact” with this component, each click will change amount of stair and the pitch.
This was strictly a study experiment. This component is only suited for quick study models as a placeholder of an actual stairs.

I have looked around and was not able to find similar component, so I am posting it here. Hopefully I do not repost something that you all have already. If so I am trully sorry for wasting your time. I hope you find it useful.
