1. Whether they are made of wood metal stone or mixed materials metal and wood stone and glass all stairs follow the same common design rules but their variety of shape is unlimited This is why no single software would be able to cover all the stair shapes and styles However it can analyse every aspect of a stair up to fabrication details or give at least the foundation of the more complex ones Stair examples I 1 PRESENTATION StairDesigner VI is a software that helps designing stairs to measure It was developed by BOOLE amp PARTNERS editor for professional software since 1988 whose product range benefits of the experience of thousands of licences used in more than 30 countries StairDesigner VI is available in the following 4 versions StairDesigner VI Std Standard version limited to printouts in A4 format StairDesigner VI Pro Prints out templates on a scale of 1 1 StairDesigner VI Pro DXF Prints out 2D and 3D DXF files StairDesigner VI Pro RB Optimizes concrete stair coverage PS I 2 INSTALLATION StairDesigner VI can be installed on every personal computer that runs with Windows Windows 98 2000 XP Pro Vista You can install it with the file InstallStairDesigner exe that is available on CD or the website www boole eu When you execute the file InstallStairDesigner exe the following window opens ES Installer StaiDesigner 6 06a Select Installation Langage he Starbesi2. Perpendicular Step Penetration in Stringboard Rear Offset Joint Thickness _ Priority to Risers Step rear Overlap Upper Offset Lower Offset Maximum Penetration in Newel Post Steps Assembly Steps Risers In the upper right above example There is a nosing of 40 mm There is a priority to the back of the steps on the risers The risers have an upper and a lower offset of 10 mm in the steps In the lower right above example There 1s no nosing There is a priority to risers at the back of the steps The risers do not have any offset P26 Perpendicular Penetration in the Stringboard The penetration of the steps in the stringboard allows when there 1s no offset not to increase the cutting dimensions and to machine the stringboard perpendicularly to 1ts front Step Offset Both parameters Front offset and Rear offset define the offsets on the sides of the steps that penetrate the stringboard pictured in grey below Step and Riser Joints These joints allow some space between the steps and risers and their cut string They are mainly used for the mortar in marble stairs Sh bakes A e ite P27 V 3 STEP SHAPING The step shaping corresponds to a set of curves that is applied to the nosing and the left and right sides of the step either separately or altogether In StairDesigner these shapings are created from the available curves step 5hapings Shapings Ref
