Use Parameters to Make Quick Changes in Fusion 360

By Poppy Mosbacher. Posted

If you use Fusion 360, you’ll be familiar with specifying dimensions to create basic shapes. Setting parameters is an extra step, that speeds up the design process.

Perhaps you want to change the diameter of all the circles in your design, or increase the width of a box by a third. Learning how to add parametric constraints and applying them at an early stage creates another level of freedom to experiment.

Change Parameter Tool

To discover just how useful the Change Parameter tool is in practice, we designed a cardboard construction kit for children. We added lots of User Parameters, so when we want to make a change, we just edit the value in the dialogue box and all the measurements that have the same name, automatically update. This turned out to be important when we used recycled cardboard to laser cut the design. The packaging boxes were of different thicknesses, so all the connectors needed to be adjusted to make all the pieces fit together. Without preset parameters this would have been time consuming and we might have given up, but they were changed in an instant.

Here's a video that walks you through the process of adding User Parameters:

Taking this feature even further, Andy Clark gives a detailed tutorial on how to use parameters to create moving mechanisms in issue 20.
