VISRETAIN and viewports question

[santhoulakis]

Maybe quite basic, but how VISRETAIN works with viewport layers?

To illustrate my question, let's assume we have  Drawing A with a layer named "Walls" coloured green.

We xref this drawing to Drawing B. With VISRETAIN set to 0, I understand that no matter what colour we assign to "Drawing A/Walls" layer, everytime we reload the xref, "Drawing A/Walls" will be coloured green in the Model. 

But what is going on with the viewport colours in layouts? If we create a layout with a viewport in Drawing B where we set the "VP Color" of "Drawing A/Walls" to be say red, next time we reload the xref the layer "Drawing A/Walls" for that viewport will have Color set to Green and VP Color set to Red? Or what?

Why not testing, better to learn and faster.

VISRETAIN simply controls XREF changes from appearing in your top file; nothing more and nothing to do with viewports.

When you turn it off, you're pretty much at the whim of the last person to save the XREF file. Pretty much your described problem.

Just did.

Colours of Viewport are also following the source drawings' layer settings. Hence, in my previous question reply would be "The VP Colour will also become Green everytime the xref is reloaded".

Which makes VISRETAIN 0 practically useless for most of the cases.

I am almost sure, though, that at some point (maybe in Civil 3d 2019 or older) VP Colours used to override the source drawings' colours with VISRETAIN being 0? Or is it just wishful thinking?

If so, then it's really an OLDer version

VISRETAIN 0 lets the XREF dictate the layer properties in the referencing drawing. If you don't want that, don't set it to 0.

Just found out. VISRETAINMODE is the command to control which of the layers properties will synchronize or not when VISRETAIN is  set to 1:
