qtvismach, a axis toolpath was created by MarkoPolo

I did simulations of my xyza machine and I have a problem with the tool trace in the A axis. I would like the entire tool path to rotate around the A axis, which would result in drawing a milled solid.
Does anyone have a qtvismach file with a similar configuration as an example that would help me configure it properly?

The second problem is the transparency of the solid.
e.g. "solid = Color([1, 0.6, 0.6, 0.5],[solid])" I think the third parameter 0.5 should be the color opacity or transparency value, but it doesn't work.
Is it possible to make semi-transparent objects in qtvismach?

I needed to modify primitives.py Color class for transparency:

Code:

class Color(Collection):
    def __init__(self, color, parts):
        self.color = color
        Collection.__init__(self, parts)

    def apply(self):
        GL.glPushAttrib(GL.GL_LIGHTING_BIT)
        GL.glMaterialfv(GL.GL_FRONT_AND_BACK, GL.GL_AMBIENT_AND_DIFFUSE, self.color)
        if self.color[3] < 1:
            GL.glEnable(GL.GL_BLEND)
            GL.glBlendColor(0, 0, 0, self.color[3])  # rgba

    def unapply(self):
        GL.glPopAttrib()
        GL.glDisable(GL.GL_BLEND)

The the alpha setting is honoured.

Does mill turn not help with the A axis?

If you mean the tool path to be drawn wrapped around a zylinder, this is currently not possible. All the logger, that is used to draw the toolpath history, does is collect collect coordinate values. It has no concept of a rotational center at all.

I modified the primitives.py file, but it didn't change anything, there is no transparency. I tested on various configurations. Is there anything else that needs to be modified?

As for the tool trace, the lathe configuration does not change anything either.
In this video you can see that the tool path rotates around the C axis, so I think it can be done.

well aside from setting the color opacity of the part like you showed, but the opacity is 1.0 most clear - 0 solid.
that does seem back wards so you could change the code a bit to do the opposite.:

Code:

        if self.color[3] < 1:
            GL.glEnable(GL.GL_BLEND)
            GL.glBlendColor(0, 0, 0, 1 - self.color[3])  # rgba

You can see the A axis spindle is see through.

Well, it actually works for you.
I check on two virtual machines and one real machine, but it doesn't work on either of them.
This is not a fourth value problem, because I have different values entered in different objects.
In the /usr/bin/millturngui simulation I also changed the fourth value, with no effect.
I don't know what the problem could be

edition
Yes, /usr/bin/millturngui is in TK, but qtvcp vismach_millturn doesn't work either
