Default parabolic result


Super Moderator
The online Help explains the Conic command fairly well.

If the Default Parabolic Result is on (orange), the conic curve will be a parabola (not a hyperbola or ellipse)

The type of conic arc depends on the value of the parameter or other constraints that we have used to define it. According to the online help:

Parameter: ratio ranging from 0 to 1 (excluded), this value is used to define a passing point (M in the figure below) and corresponds to the OM distance/OT distance.
If parameter = 0.5, the resulting curve is a parabola
If 0 < parameter < 0.5, the resulting curve is an arc of ellipse,
If 1 > parameter > 0.5, the resulting curve is a hyperbola.

Do you think that we can get a parabolic arc by setting the parameter value > 0.5 and highlighting the default parabolic result option? I don't think so.

Afrouz, I agree with you, and I think you've discovered a software bug. I guess the parameter value is used to define the conic curve, and the "parabola default" option is ignored.

When I'm using conic curves for design, I don't care what kind of curve I'm using, provided the curve does what it's supposed to do.
