![]() One of possible ways to create a circle when you start from a square shape is to bend each segment up to 90 degrees. While you are changing the curvature of a segment, a number near the cursor changes from 0 (straight line) to 180 (semicircle). If you move a round handle in one or another direction, the corresponding segment will bend inside or outside of the contour creating an arc. In the contour editing mode, the program also displays round handles in the middle of each segment of the contour. To remove a contour point, right-click on it and select Remove Contour Point. To add a new contour point, right-click on the contour and choose Add Contour Point. To change the shape of the outline, you can move the contour points. The program will display the outline of the opening with diamond-shaped handles at the corners called "contour points". The resize handles will disappear, indicating the contour editing mode. To modify the shape of an opening, right-click on it and choose Edit Contour Geometry from the context menu. When a staircase leads to a landing, that is below the ceiling level, and the slab opening is not needed, you should convert the object type from Stair to Furniture in the Type & Representation dialog. This can be used when a staircase should stay at the top of a platform. By increasing the Elevation, you can raise the bottom stair level. By default, staircases take the whole space between the floor and ceiling. The Elevation parameter defines the distance between the bottom of a staircase object and the floor. The Handrail Height is the distance between the floor of the upper story and the top of the 3D model. Consequently, you should indicate the handrail height in the Inspector in order to make the upper step match the floor level. When there is a handrail, the upper step is located somewhere below it. This lets the program automatically match the upper step with the floor level of the story above. If a staircase has no handrail, the upper step coincides with the top of the 3D model. The Handrail Height parameter is intended to take the handrail height into account. Nevertheless, some adjustments can be made using the two parameters explained below. This is why there is no way to change the object's height directly. The program automatically adapts the height of staircases to the story height. All of them affect the object both in the 2D and 3D views. This set of tools includes three buttons: Flip Horizontally, Flip in Depth, and Rotate 180 degrees. The Flip buttons in the Inspector let you flip or rotate a staircase. To rotate an object, use the Rotate tool in the Inspector or the rotation handle on the floor plan. The handles are not displayed when the object dimensions are locked. To resize an object on the floor plan directly, drag one of the handles on the object's selection frame. To resize the object proportionally, select the Maintain Aspect Ratio option. To resize an object, make sure that its dimensions are unlocked in the Inspector. The geometric properties of a staircase can be found in the Object Properties tab of the Inspector. Most of the staircase parameters are located in the Inspector, where you can change the object's geometric properties, or set up how the object looks on the floor plan or in the 3D view. The Applying Materials section explains how to apply materials to objects. Operations common for all object types are discussed in the Basics section. ![]() In order to apply the proper object type, use the Type & Representation dialog. If you have imported a 3D model of a staircase, the program sets it as the Furniture type by default. The Stairs object type differs from others in the ability to create an opening in the slab above it.
