AcadCalcStair is an AutoCAD add-on software that offers parametric modeling and drafting for stairs and rails. With Auto Drafting feature and parameter-based inputs, it automatically creates stair plan and elevation drawings. It also includes a calculator for easy calculations.

One of the key features of AcadCalcStair is its parametrical modeling and auto drafting capabilities. The program creates the drawing based on the parameters provided by the user, including Stair Plan and Elevation with all main dimensions. Additionally, it allows for applying different scales and the option to have a visible or hidden (behind the wall) representation of Stair Elevation.
The program is also equipped with a calculator that performs mathematical operations, such as Slope, Triangle, and Stair calculations. It supports all formats of numbers, including architectural, fractional, decimal, and AutoCAD formats, providing users with flexibility when working on their projects.
Another key feature of AcadCalcStair is its ability to modify AutoCAD objects. The program can directly perform AutoCAD commands using the results of calculations, including move, copy, scale, and array. Users can even get distances from AutoCAD and use them in calculations, which is one of the numerous options available to them while working with the program.
Lastly, the results of calculations are automatically placed in the protocol, where the user can add comments. The protocol contents can be copied and transferred through the clipboard to any text editor, making it easier to share the data with others.
In conclusion, AcadCalcStair is a powerful tool with a variety of features designed to streamline the drafting process for architects, engineers, and draftsmen. Its parametrical modeling, calculator, and AutoCAD modification capabilities make it a valuable asset for any project. Plus, its ease of use and user-friendly interface ensure that users can navigate and work with the program confidently.
