To design a steel ladder in Revit, you will first need to create a new project or open an existing one. Once you have your project open, follow the steps below:br br Create a new family: Click on the "Family" button under the "New" section of the "File" menu. Choose "Metric Generic Model" as the template.br br Draw the ladder shape: In the family editor, use the "Line" tool to create the basic shape of your ladder. You can create the shape by drawing individual lines or by using the "Rectangle" tool.br br Add dimensions: Once you have drawn the basic shape of your ladder, use the "Dimension" tool to add dimensions to your design. These dimensions will ensure that your ladder is the correct size and shape.br br Add rungs: Use the "Line" or "Rectangle" tool to create the rungs of your ladder. You can use the "Array" tool to quickly create multiple rungs at once.br br Add connection points: To make sure your ladder is properly connected to other elements in your design, add connection points to the top and bottom of the ladder. These connection points can be added using the "Point" tool.br br Add materials: To make your ladder look like steel, you will need to add a material to it. You can do this by selecting the ladder shape and then choosing a steel material from the "Materials" library.br br Save and load the family: Once you have completed your ladder design, save the family file and load it into your project. You can then place the ladder into your design by selecting it from the "Family" section of the "Insert" menu.
