Parameter Help - Equidistant spacing

bryce.remington — Mon, 16 Oct 2023 15:47:47 GMT

Hey all,

Newer to Fusion 360 and trying to think of the best way to do this.

I have a circle, currently in this photo is 50mm. But it could change depending on the parameter CircleDiameter.

Within the circle, I have 3 lines that are spaced at 120 degrees from each other (equally spaced in the circle).

I am going to have a point on each of the lines that needs to meet this condition:
The points must be on the line so that the spacing between each point is the same distance (or as close to) as the spacing from each point to the outside of the circle.

I know this is likely a simple(r) math formula, but I am struggling to think about how to approach this. Right now I have a formula that is very clunky and requires manual hand holding to get right.

PointSpacing = (Circle Diameter / 4) - SpacingPadding

Spacing Padding is a flat number like 4mm that I manually enter to get the spacing to align. But I would like to automate this so just updating the Circle Diameter is enough to adjust the points correctly.

Hi,

If you say what you want to achieve in the end it might be possible to recommend a more targeted approach.
