[Bug?] Conic Curve Sketch + Parametric Modeling

[Anonymous]

I'm trying to create a parametric curve where the rho value is defined with a user parameter.  It takes it the first time, but appears to be static; i.e. changing the parameter has no effect on the curve once it's been initially created.

Is this working as intended or a bug?  Any idea of a workaround?

It's not a bug, exactly, more like "something we haven't finished implementing yet".  It's a reasonable request, I'd agree.  I would put it into the Idea Station.

Thank you for the prompt feedback.

Good to see, I did post it as a feature request here:  https://forums.autodesk.com/t5/ideastation-request-a-feature-or/conic-curve-parametric-modeling/idi-...

In the meantime, if anybody has any way to work around (perhaps a different type of curve?), I'd appreciate it.  

Basically, I'm trying to make a shape similar to a snow plow.  It's curved in both the xy and the xz planes.  Right now I'm parameterizing multiple fillets through a formula to get the effect I'm looking for, but this isn't really ideal to do in 3d, and it's not easy to design to a specific dimension.

P.S. I'm betting the "bend" ability could do what I'm looking for (assuming it's implemented with parametric cad in mind). https://forums.autodesk.com/t5/ideastation-request-a-feature-or/bend-body/idi-p/5291287

The parametrization of the Rho value would be great for me too.

In a sketch in which a conic curve is mirrored, when one changes the Rho value of 1 curve, the other curve with the mirror constraint attached does not change its Rho value. 

This leads to unequal sketches on both sides of the mirror line.

This while there is no visible indication from Fusion that the mirror constraint is invalid.
