Hey, bellow are the rules to build a simple stairway from a rectangular base.It is very simple, and the results are nothing spectacular, but it might be interesting for some one out there 🙂The pictures show how we can parametrize the function call, and control the model through the inspector...[ATTACH=CONFIG]15682[/ATTACH][ATTACH=CONFIG]15683[/ATTACH][ATTACH=CONFIG]15684[/ATTACH][ATTACH=CONFIG]15685[/ATTACH][ATTACH=CONFIG]15686[/ATTACH]
