Parametric Modeling in Revit: Tips and Tricks for Creating Complex Shapes

Revit is a powerful tool that allows architects and designers to create complex shapes and designs with ease. One of the most popular features of Revit is its ability to create parametric models, which can be used to design and simulate real-world objects. In this article, we will explore how to use Revit's parametric modeling capabilities to create a radius that is controlled by the number of corners in a polygonic form.

To start, open up your Revit project and create a new family. Draw a simple shape using the lines tool, such as a rectangle or a circle. Then, select the shape and go to the 'Edit Family' mode. From there, you can access the parametric modeling tools by clicking on the 'Parametric' tab in the ribbon.

Once you are in the parametric modeling mode, you will be able to see all of the different parameters that are available for your family. To create a radius that is controlled by the number of corners in the polygonic form, you will need to add a new parameter and then use it to control the shape of the radius.

To do this, click on the 'Add Parameter' button in the parametric modeling mode and choose the 'Number' option from the drop-down menu. Name your parameter something like 'Radius Corners' and set its value to 6. This will create a new parameter that can be used to control the shape of the radius.

Next, you need to add a nested component to the family. To do this, click on the 'Add Component' button in the parametric modeling mode and choose the 'Line' option from the drop-down menu. Name your component something like 'Radius Lines' and set its value to 6. This will create a new line that can be used to control the shape of the radius.

Finally, you need to add a DC (dimensional constraint) to the family. To do this, click on the 'Add Constraint' button in the parametric modeling mode and choose the 'DC' option from the drop-down menu. Name your constraint something like 'Radius DC' and set its value to 6. This will create a new dimensional constraint that can be used to control the shape of the radius.

With all of these steps complete, you should now have a parametric model that is controlled by the number of corners in the polygonic form. To see how it works, select the family and go back to the 'Edit Family' mode. From there, you can adjust the value of the 'Radius Corners' parameter to change the shape of the radius.

For example, if you set the value of the 'Radius Corners' parameter to 8, the radius will change to have 8 corners instead of 6. You can also use the parametric modeling tools to create more complex shapes and designs by adjusting other parameters and constraints in the family.

Overall, Revit's parametric modeling capabilities are a powerful tool that can be used to create complex shapes and designs with ease. By following these steps, you should now have a good understanding of how to use Revit's parametric modeling tools to create a radius that is controlled by the number of corners in a polygonic form.
