Graphic overrides: background fill transparent to opaque

Bruce — Fri, 19 May 2023 13:21:58 GMT

I have slabs that have a transparent background fill, that I would like to change to white on certain conditions...but it seems this is beyond graphic overrides. Am I missing something?

It seems that if your slab has a cover fill with transparent background pen, then the background pen colour in GO will have no effect.
However if your slab cover fill has any other background pen colour, then the GO will work.

I guess the logic is that there is no background colour to override.

The only way I can get it to change is to override the actual fill as well to a solid fill, but then you lose the foreground colour and pattern.

Yes - not sure I understand the logic of this. Seems like an oversight to me.

Also if you set the slab cover fill to use the screen background pen instead of transparent then the GO also works.
But then you lose the transparency in plan.

To me it is a bug that the transparent background is ignored.
I am sure this was brought up in either the beta or developer forum, and it was explained that as the background is transparent, there is nothing to override.

I think it's a bug too. You can force an opaque background to transparent (i.e. change a pen to 0), but you can't change a transparent background to opaque.

I like this logic. It makes sense to me as it removes the risk of obscuring things that should never be concealed.
IMHO.

Surely that should be up to the user?

I'm with Bruce
I would say because I am applying a cover fill and I am setting the pen to transparent - I should still be able to override that pen.
Just because it is transparent, it doesn't mean that I want it to always be transparent.

If I always want a transparent cover fill then I can turn the it off - then obviously there is nothing to override at all.

Maybe have an option of have NO background fill.
