Strange entry behavior for Engrave.

Here are three curves: The bottom one is a circle at Z=0. The top right curve is irregular, with varying Z. The top left curve is the same as the top right curve, except projected onto Z=0.

In all cases, cut depth is 10mm, with steps of 2mm.

======

In the first picture (order 1.jpg), the top right curve is chosen first, then the top left curve, then the circle. In this case:

At the first curve the first entry is as described by the Entry choice, in Parameters, and is tangent to the curve. All later entries are simply vertical.

At the second curve, all entries are as described by the Entry choice, in Parameters, and are tangent to the curve.

At the circle, all entries are as described by the Entry choice, in Parameters, and are perpendicular to the circle.

In the second picture (order 2.jpg), the top left curve is chosen first, then the top right curve, then the circle. In this case:

At the first curve all entries as described by the Entry choice, in Parameters, and are tangent to the curve.

At the second curve, no entries are as described by the Entry choice, in Parameters. All entries are simply vertical

At the circle, all entries are as described by the Entry choice, in Parameters, and are perpendicular to the circle.

Sorry about the missing pictures. Maybe you can sketch them for yourself.

It used to be easy to upload a picture to this forum. Not any more.

After an hour or so preparing this example, I'm not willing to spend more hours putting these pictures on a web site, figuring out how to use BBC code to point to them, etc.
