G2 constraint for 3d sketch spline

[mikkoYWYF7]

Hi,

Trying to learn Fusion and having hard time with 3d sketches.

Is it possible to have a g2 connection along Y-axis and still keep corner on Z-axis? Curvature constraint affects both axis. This is between 2 spline sketch.

Thanks.

Here´s couple of pictures. trying to get smooth side along Y-axis and stil keep that corner on Z-axis.

Here´s the file.

Thanks.

yes, you can do this.  To keep the corner on the z axis, create a construction line along the z axis, the constrain the point to that line using Coincident.  Then, just add a Curvature constraint between the two curves.  If you want one of them to react to the other, you can Fix the tangent handle of one of them.

Thank you. This helped. It´s still impossible to get the shape I would like to. Those Bezier handles are pretty useless.

Thanks.

For a 3D spline, the handles can only be manipulated using the Move command.  You cannot just drag them, unless they are 2D splines in the sketch plane.
