![]() Indeed, you can create the array directly from an extrusion. Ideally, in a family, you need to make the rung as a family and then load it to the main family. Place the first rung from the bottom, then create an array. But before we can use the formula, we need to prepare a few things. To calculate the number of rungs, we need to use a formula. Here I created two parameters to control the ladder.ĭon’t forget to flex the parameter to test if they work correctly. This family’s basic parameter usage is controlling the ladder height and width. We are going to use it in a yes/no parameter. ![]() According to OSHA standards for fixed ladders, a ladder more than 20 feet height must have a cage for safety.You need to calculate the number of rungs with a formula. The number of rungs follows the ladder height.We need to use parameters as labels for the dimension to control the ladder size, such as the width and height.If you want to develop it further, you can edit it to add more details.Ī few parameters you need to pay attention to are: The case that we use is a ladder with a cage. This post assumes you are familiar with creating families and parameters to control the dimensions. We will use formulas and conditional statements to control array and element visibility. In this post, we will see how to use parameters in a Revit family for more advanced usage. We can control the size, provide information, ensure standards, and much more. One benefit of using the Revit family is the parametric capability. Associating Main Family Parameter with the Child Parameter.
