Improved Stair Functionality in Revit 2014

Throughout the Ideate series of Revit 2014 Blogs and Videos Ideate has introduced a number new functionalities within the Revit product. In continuation of this series Ideate brings you an improvement to the component stairs introduced in Revit 2013. Stairs and railings are a continuing multi-year project with this year's improvements being made to seven areas within the component stairs.

Additional Location Line options: Revit 2013 introduced the ability of sketching component stairs by selecting a location line other than the center of the run. Specifying the left or right side of the stair run allowed designers to sketch a run of stair along a wall. New to Revit 2014, two additional location line options are available and the three existing location lines readjusted. Location lines now include Exterior Support: Left, Run: Left, Run: Center, Run: Right, and Exterior Support: Right. Now designers are able to sketch on the exterior sides of stair support elements, on either side of a run, or down the center of the run, opening up a number of options for sketching stair runs. Figure 1.

Modify the run width before or after stair creation: Prior to Revit 2013, the width of a stair run could be set in the Properties Palette. In Revit 2013, the minimum run width was set in the stair's Type Properties. In Revit 2014, the width of the stair can be set in the Actual Run Width option in the Options bar. Additionally after a run is created, it can be selected in it's sketch mode and the width of the run modified with grips or by using a width temporary dimension. Figure 2.

Modify the Landing Shape: Automatic Landings include new control grips to modify the landing leg length. This is the point where the landing connects to the run. Figure 3.

Automatic Landing Reshaping Behavior: Initially when an automatic landing is created, the edge of the automatic landing remains flush with the edge of a stair run. In Revit 2014, control grips are available along the edges of the landing to change the shape of the landing. Additionally modifying a run will also modify the landing shape . Figure 3.

Automatic Landing Creation: When creating a U-shaped/switchback stair that includes varying run widths, the automatic landing is initially created with a depth equal to the width of the narrowest run. The landing depth can be modified after the stair runs and landing are created through the control grips along the edges of the landing.

Accurate Modifications: Temporary dimensions are now available when modifying a run's width, the landing depth on a U-shaped/switchback stair, the radius of a spiral stair, and the distance between stair components. At the time of run creation, listening dimensions are available for both straight runs and arc runs. Figure 4.

Snapping reference Improvement: More snapping capabilities are available during the creation and modification of stair components. For example, run to run vertical, horizontal, parallel, and perpendicular snapping is available when dragging the stair path end point. Figure 5.
