Parametric tyre builder with conditions in Fusion 360

thingiverse

I'm just starting out with Fusion 360 and came across a neat trick whereby you can implement conditional logic using math functions supported by the expression builder. The two I use are min and max. Here's a pseudo code example: if (variable_a < 10) variable_a; else 9; Sadly, if/else statements are not yet supported in Fusion 360, but the above can be implemented using min: min(variable_a,9) I have wrapped up these concepts in a parametric project that allows you to fully configure a tyre using parameter values. There are two components representing a road and off-road tyre. I have shared my fusion project file so anyone who is interested: * Might be able to learn from a functional parametric example * Create their own custom tyres based on my design and their measurements It has worked for well for my daughter's toy stroller. I'm not making great use of constraints in this project as I've found Fusion gets upset easily when trying to re-compute updates (change parameter values) in relationships established by constraints. In this project, I've used calculations and basic trigonometry to link/constrain points, and it has worked quite well. You'll be able to see everything adjust in proportion with parameter value updates which is a pretty neat outcome. If you think I could have done something different, please do leave a comment; I'm always looking to improve my knowledge. Creating a tyre I have used a naming convention that represents user-friendly parameters and parameters that belong to the model which should not be changed. To create your own tyre, simply change the values for all parameters that end in _value. These parameters are intended to provide an abstraction to the actual parameters used; they also enforce validation so that the model is not invalidated with erroneous data. I have also saved them in my favorites, and it makes things easier. Disclaimer! I'm not a tyre designer, and this may lack the foundations of a sound design, so use with caution! I am using the road variation on my daughter's toy stroller as the plastic wheels do not grip our hardwood floor. It is printed in TPU; it does what I need. <iframe width="560" height="315" src="https://www.youtube.com/embed/IStVrcMrh7M" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
