Re: Pads front and F.Cu visibility, possible bugs?


Yeah, for the render tab, this seems to be what is indicated anyway. I guess this would also mean changes to all of the ElementVisible() things as well.

Still this doesnt really explain why the pads copper part is not disabled when the copper layer is disabled, the other parts for the pad is disabled with the layer setting. like the paste and mask layers.

The only difference I can think of is that the copper is a connectivity part, but I have been unable to find why this should interfere.

As you noticed, one can only define simple layer visibility dependencies
in GAL using SetRequired() method. Effectively, you can quickly disable
a whole layer when another is invisible, but it does not handle well
cases of e.g. texts whose visibility should depend both on the layer and
the parent object visibility.

Perhaps we should define visibility rules per class and not per layer,
so we can check additional conditions.

I started investigating this some more, there is much more rendering
problems here.

for example, disbling rendering of front footprints disables all the
F.Silk, F.Fab, adhesive and many more.

Disabling the rendering of Text on the front only disables text
belonging to a footprint, no other. Basically the Render tab does not do
what it says at all.

A lot of this seems to because of what is set in pcb_draw_panel_gal.cpp:417

There is a lot of SetRequired-> (layer, layer)

And that implementation seems broken, could someone shed some light on
the purpose there?

If you use legacy renderer then turn off Pads Front and Pads Back under
the Render tab on the right the pads disappear. If you are in GAL mode
they remain visible.

Given that the legacy canvas will hopefully be removed in the v6
development cycle, I guess this issue will go away.
True, but I wanted to point out that as far as I was concerned it
hasn't always been this way. I would still expect the pads to
disappear if I turn off display of front and back pads.
