Background changed suddenly. Can't change it back..

Jim Canale

Hi!

I was using V14.2.17 today (3D mode), and the background suddenly went from a blue/white gradient to a bright yellow gradient   At the time this happened I was not doing anything except extruding a polyline.   I can't work with the yellow.  Can someone tell me how to fix this?

 I opened the drawing explorer and double clicked the views icon.   There was only the "home" view.  The background was set for a blue and white gradient.  I changed it to something different and hit the "regen" button.  No change to the background.  I tried a solid background.  Again, no change.  

Ideas?

 I submitted a support request regarding the background gradient (BKGGRADIENTON); after opening a drawing sent by one of the Bricsys support staff I noticed that my background colours changed, my colours are set to a couple shades of grey and the colours set in this drawing are pale yellows.  As it turns out the background gradient is stored in the drawing as it is a view, which seems OK, but I think that when the drawing is opened BricsCAD should just see that the gradients are turned on and fire whatever function to show the background gradient using the current user's defined colours and not load the colours that are saved in the drawing.

Anyway, the way to switch back to your defined gradient background colours is to run the BKGGGRADIENTON command twice and then save, once to turn off the gradient display, and the second time turns on the gradient display using your colours, following this, save your drawing so that the next time you open it the gradients displayed use your colours as the colours will now be saved in the drawing.  If you then email this drawing to somebody else, when they open it they will see your background colours.

 Thanks for your reply, but I tried to run BKGGGRADIENTON, and neither program (V14 or V15 recognized it).

The background color is controlled by the Background property of the current view. Please notice that the 2DWireframe and Wireframe visual styles always use the background color which is defined by the BKGCOLOR system variable. If no saved views exist in the drawing the background color is always the one defined by BKGCOLOR, except for perspective views in a rendered visual style.

 Sorry, that should be GRADIENTBKGON, and I was wrong again with GRADIENTBKGOFF turning off the gradient background, GRADIENTBKGON does not work as a toggle.  In your case once the drawing is started, run GRADIENTBKGON to reload the colours from your settings and then save the drawing.  As Louis said, you will need to be using a 3D visualization style that supports the gradient backgrounds.

 I must not be understanding something.  None of this has an effect on the file I was working with  (the one with a yellow background.)   So for the moment, I will assume that drawing got corrupted somehow...     I created a new drawing and saved a view with a red gradient background.  I then tried GRADIENTBKGON, or GRADIENTBKGOFF.  All GRADIENTBKGON, did was give me a grey gradient.  No matter what color gradient I set in the view, the gradient I see is grey and white.

Yesterday I was finally able to "fix" the file.  I opened the drawing explorer, clicked on "Views", selected the "Home" view, and deleted it.  When I re-entered model space, I now had a black background, which is what I wanted, and started with.    I noticed today when I re-opened the file that the "Home" view has been restored, although my model space background remains black.     I'd still like to know what caused the background to change to yellow, then red, then back to yellow, but I suspect that will remain an unsolved mystery.

Thank you to the people who tried to help me with this.
