We’ll write “max,” and parentheses, followed by 170mm. Inside the minimum, we’ll place the maximum value of 200mm, a semicolon, and then we need to define the minimum value within the max function. The Min and Max functions require two expressions in the following format: min(expr1 expr2). Changing the parameter outside this range will break the model or make the model larger than desired.Ĭreate a new User Parameter with your desired parameter name, and I like to add the word “Limit” to the end. Working on this tea kettle design, I don’t want it to be smaller than 170mm or larger than 200mm. Number one – use min and max values to ensure your parameters stay within an expected range. Three parameter tricks you wish you knew earlier. Decimal powers round at the eighth decimal place. For example, returns 2.688E43 for 100.Ĭan construct unit valid equation that can go invalid “pow(3.0 d12)”.

The following functions are all available in Autodesk Fusion 360 to use with User Parameters. However, changing the original dimension will continue to update the parameter itself (and all areas you use the parameter). You will also find that parameters created ‘on the fly’ do not show the parameter name after you save them. Note: there are no spaces between the parameter name and equal symbol.

After the parameter name, use the equal symbol (=) and the desired value.

Within a dimension input (Sketch or Model feature), define the parameter name.

Define a parameter name, equal symbol, and define the parameter value without any spaces. In essence, you can use model parameters and user parameters in the same manner – calling the parameter name in both sketch dimensions and modeling features. Note: Parameters created on the fly are considered “Model Parameters” and not “User Parameters.” That’s because they’re derived from the model itself. Fusion 360 automatically adds “on the fly” parameters to your favorites, so that it is easy to find in the Parameters dialog. This helps you create parameters without the need to open the Change Parameters dialog.
