Ellipse Arc Approx by spline flaws

[CVH]

For Tile2Hatch I reduce all entities to bare line-segment.
In some cases there are more routes to do this.
Including all routes as options....
For ellipses one is the most common form:

Code: Select all

polyline = ellipse.approximateWithArcs(options["ellipseSegments"]); 

The second option is parsing it to the splines section and handle it there with specific options for splines.
Using the inbuild method:

Code: Select all

splines = ellipse.approximateWithSplines();

The first spline in the returned set starts where the Ellipse Arc did.
The last retuned spline always overshoots the end.

What am I doing wrong?

Can't find any end treatment in 36 hits searching the Qcad project for "approximateWithSplines"

REllipse:: approximateWithSplines is highly experimental and not used at all by QCAD. As approximateWithArcs is far superior, spline approximation might be removed in a future version.

Good thing I came up with an alternative....
