Fills+window background

[Anonymous]

Hi I'm having a little issue with fills.

The attached image shows two fills side by side,
- both are 25% Pen 1 (Black)
- Left is set to window background colour, Right has the background set to a white pen.


Obviously the background of the window is white - so any ideas why the fills look so different? (did I miss an override somewhere?)


Thanks!

There is no image attached.

Are both your white pen and bacground colour RGB 255, 255, 255?
Or at least the same values as each other?

I just change my background to white and could see no discernable difference.

I just check the "Automatic pen colour visibility adjustment in model views" option in the Work Environment (on screen options).

This makes a slight difference as it will be changing the white pen to grey if you have that option turned on (I always thought it went black on a white background but there you go! - that's one reason I don't use white as a background).

Thanks for the reply even though the image did not attach.

I didn't know about that automatic adjustment, thats useful. However, that only makes a slight difference to the colour. As you can see the difference is quite substantial.

Two more images (I can't seem to add images to the previous post)

My workaround at the moment is to:
- toggle the background fill override
- chose a colour,
- chose the window background again
- toggle the override back off

that seems to get the "-1" to appear

The brick material fill on the left is how it appears as default, and the right is after the background has been toggled on and off.

I see you are using a cut fill with Building Materials.
Does the same thing happen for a regular cut fill or drafting fill?

Go into your fill (surface) settings and make sure the background pen is set properly there.

Hi Barry,

It happens to all fills (cut/building material - anything that uses the background pen).

Whenever the fill background box doesn't display "-1" beside it then the background colour comes in as a dark grey.

This is working just fine for me.
I could only achieve a difference when I turned on the "Automatic pen colour visibility adjustment in model views" option in the Work Environment.
Otherwise both fills looked the same.
I am wondering if this might be graphics card driver related.
Could you save these fills as a PLN and share it on Dropbox or something similar and post the link? I would like to look at the file. If it works on my computer but not on your, then it may be hardware or driver related.
