# Isocline Curve

## Isocline Curve

Be possible to create curves on bodies, quilts, surfaces, with an angle to a specific direction.

See from solidedge:

In both videos, the isocline curve is applied to a sphere. The particular case of a sphere is simple to create those curves. But for a complex part like this, is not that simple! Specially with the variable radius.

Besides Isocoline, I would also find useful to generate constant U or V curves. When I modeled in Mastercam, or previously in very Intergraph expensive CAD software, one of the most used curve generatin methods when deoing surfae modelng was generating curve on suurface along same U or same V. We can do it only in Import Data Doctor, and I used to use it in regular modeling practices. One of the workarounds is to Copy a surface with the option to untrim it, then extend inwards one of its edges, then useing the edge to generate the constant U or V curve. It would be a lot simpler for when we need it to be able to generate the curves directly, either by specifying a ratio parameter to select from 0 to 1, and the diretion, U or V (in case of nurbs curves, there are no UV curves in planar surfaces), and alternatively, also selecting a point or an existing vertex to specify the constraint where the curve needs to pass, and the software would calculate the U or V parameter to generate the U or V curve.
