A handy reference for Fusion 360 parameter functions
Fusion 360 has an incredibly useful facility whereby you can make a model dimensions fully flexible through not entering fixed dimensions but instead make them a calculation. The calculation will be dependent on other attributes of the model in conjunction with mathematical functions.
I had two problems in a recent model. The first one was where I had a dimension that I wanted to convert into a plain value rather than being associated with mm. This would allow it to be used in an equation. The second problem was needing to round a calculation result down to the nearest whole number.
The answer to the first problem was simple and obvious – divide the value in units by one unit. So something 200mm long becomes just plain old 200 when divided by 1mm. I was a bit red faced on that one.
On the second problem I searched everywhere in the Autodesk forums and found people mentioning ‘floor’ ‘ceil’ and ’round’ but it took a lot of searching to find a tabulated reference for the workings of the Parameter functions.
Having found the lookup details on the Autodesk site I have transcribed this into Woody speak which you can download as a pdf below and I have also added it to my Workshop Spreadsheet and there is a link to the latest version also below.
