Layered Viewports????

Thank you remark and I apologize for any frustration I may have created.

No frustration was created in the making of this thread. Intentional or otherwise. We're cool.

I may have to take a walk around the block though.

When you XREF a drawing from another file that file is brought in along with all of its layers. Personally I do not need these layers for my access is there anyway I can combine all these to eliminate the large quantity of layers in my file? Say by layer merging. And if I do will this affect the ability of the file to revise itself?

Explanation: What I am doing is taking a bunch of engineering drawings, XREF them into my file, then creating seperate viewports for each drawing referenced in. But the key is I need these files to adjust automatically when the engineers make changes (This is done through the XREF command from what I gathered from one of my previous posts).

I don't believe you can use the large merge command on the layers of an xref but I am not 100% sure. I do not use xrefs.

Remark I have a question as far as the application of Viewports within Layers.....Say I want to use 1 "Layout" or paper space for my model space. My model space is six XREF drawings. I make six seperate rectangluar viewports on my paperspace and assign each one to a seperate layer "Viewport 1" - "Viewport 6" I align the each viewport and lock them. My goal is to use each of these viewports seperately so I turn of viewport layers off but when I turn "viewport 1" on it will appear on the paperspace and so on for each of the rest of the viewports.

My question is I guess when I turn layers on and off will the viewports that are assigned to them "Turn" on or off as well meaning "appear" or "disappear" with the application of the layer.
