Some Blocks Display Properly, Some Don't...How Do I Fix It? Where Did I Go Wrong?

[keirvan]

Greetings!

I recently replaced my 2012 Mac Mini with a 2018 Mac Mini.

2012 Mac Mini2018 Mac Mini

Some of the blocks created on the 2012 in AutoCAD for Mac 2018 no longer display properly on the 2018 using the same version.

ACAD 2021 on 2012 Mac

Above: AutoCAD for Mac 2021 on 2012 Mac Mini - All blocks look fine

ACAD 2021 on 2018 Mac

Above: AutoCAD for Mac 2021 on Mac Mini 2018 - Most of the Electrical Components (Green) are very faint, despite being the same block composed of nested blocks.  It looks the same in the Block Editor.  Actually, all of the blocks look faint in the block editor except for the composite block shown above.  It looks exactly as above, even though the enclosure which is bright in the composite is faint when viewed alone as its own block.

AutoCAD for Mac 2023 looks the same.

Even more perplexing is that it looks fine when plotted to PDF.  But this is really hard to work on.  It really strains the eyes!

I'm very new to AutoCAD, so please be kind.  I'm completely baffled by this and have no idea where to start.  The only thing I've tried is switching graphics engines between Metal and Open GL, which did nothing.

I've attached the file.  Any help would be greatly appreciated!

Forgot to attach the file....sorry!

Hi @keirvan ,

Objects inside nested "SE 100kW" block have 90% Transparency property:

In AutoCAD on the old Mac "Show transparency" option is turned OFF on the Status Bar:

That is why the block looks "bright".

But on the new Mac "Show transparency" option is turned ON on the Status Bar:

That is why this block looks "very faint" on the new Mac.

Thank you SO much, @maxim_k!!!

I had a feeling it was something very simple, but I completely forgot about the transparency button in the status bar.  I had tried playing with the transparency, but not in the block editor so of course it had no effect.

Thanks again!
