A slimmed down drawing is attached (the eTransmittal was too large). Thanks for taking a look!
Well it's Transpearancy after all.
First thing done was select the top VP & open Properties Palette (which revaels) 90% Trans. is applied to the VP's.
Go to Transp. icon & Toggle it off and things appear normally.
I would change the values to zero at VP object level in Properties though.
BTW, All of the light grey objects in dwg have a 90% Trans. applied at the object level when viewed in Properties.
Thanks for the solution, Jay!
As far as I can tell, all the VP Transparency values for the viewports are 0 already.
Another engineer in my office put this drawing together (I'm just troubleshooting) so I'm not sure how this issue would have come about. Would someone have to select the objects and set the Transparency value?
I also see in Properties that the Transparency value for some objects is "ByLayer". How are objects set to "ByLayer" after a numerical value has been entered?
Your welcome, glad to help.
As far as how they got that way, check the Setting Variable CETRANSPARENCY which when set to -1 (default) then Transparency will be "Bylayer"
on all newly created objects.
To change the existing object Transparency "Bylayer" Use the Change command (note the dash before -CH)
-CH>select objects key in ALL>Enter>P>Enter>TR>Enter>Bylayer.
Do this twice, once in Model Space and once in Paper Space as there are objects in both at 90%.
