[How do I create reference viewports of line drawings in Elevation views?]

I am looking for the best way to set up views of elevation drawings in my orthographic model views; front, rear, etc.  These are drawings from a designer with different; CAD, workflows.  I hoped I might do them as viewport references in a vertical working plane so that when he makes an update change in elevation in 2D, I can then compare to with the model, and ensure its coordination.

 

Thanks!

Mmm... I just deleted them.

[Layer Links in 3D views]

When trying to select objects in isometric views, layer links prevent direct selection, unless I "Force Select".   How do I prevent/negotiate this?  I have no use for layer links in this context.

[Snapping to invisible classes]

If there is a newer thread please direct me.  I have just started in VW16 and I have this problem as well.  I have done the unstucking process recommended by Jim. 

 

It seems the only way to prevent this is to activate the class I want to snap to, and change the class options to Show Others.  This however still yields phantom snaps to wall components.

 

Advice?  Scripts to fix it?
