Parameter variation / Adaptive parameter

[Anonymous]

Hi Experts, 

I would like to vary a parameter within the sketch environment where each polygon's circumscribed radius varies as the distance from a point increases . i am able to define parameters but i an unable to vary each instance to a different value, as in this case its radius/diameter. How am i to achieve this within fusion?

i have attached here images of what would like to achieve.  Fusion: Polygon with rectangular array, uniform value for each controlled by a user parameter.Desired Result: i would like to vary the value of the radius parameter of each polygon with respect to its distance from the cross point.

Hi @Anonymous

I can't think of a quick way to do this with Fusion.

If you take a dimension parameter from the origin to the center of your circle, you could then set the diameter of your circle as a ratio of this line length (This bit is easy).

However - you would need to repeat this for every instance of your circle (!). You won't be able to use an array, because the array command creates an exact copy of each instance, no variation is available.

Perhaps you could post a request in the customisation forum for a script that could achieve this?

I'd love to find out if there is a better solution!?

Hi Paul, 

ratio of the distance, between target point and center of each circle, to drive the diameter is the right way but its a bit tedious if you have to do Hundreds of them.

In other Autodesk software with similar sketch environments there are " reporting parameters" that can be read and referred into another parameters expression to compute yet another parameter.  

A quick way i can think of is to import 2d cad from other software and convert them into a sketch, still trying to figure out a way to do this native within Fusion.

Reporting parameters are possible, but not instance parameters. There is no equivalent to Revit nested families or Inventor Sketch blocks.

This is why you are stuck with creating many, many reporting parameters...
