I am copying a 2d veiw and pasting to a 3d scetch plane then trying to print. The line weight defaults to one size and all angular lines are hatched. Any one know how to correct this?

Looking at your attachment it is still not easy to understand the end goal.  So you develop the package geometry, or at least parts of it (ribs, etc?), in 2d and want to overlay it on the 3d model?  When you say "print" are you saying drawing or just pictures with views?  My off-the-cuff remark would be that it is easier to make 2d (drawing) views of the 3d model and overlay your 2d package geometry over them.

Also, I believe that in 3d sketch mode, the line weights and types are kept, but when you exit it they default to a solid line type with the same weight (at least they do for us).

Like Gary, I don't understand the picture that was attached to the original post, so I'm not sure what you're trying to do.

Is it something like the picture below?:

If so, check out these tutoriald on how to use 2D images with the Sketch Tracer tool

I still don't understand what it is you want to print.  But, if you just want to print the 3D image on the screen, use File + Print. (it sounds like you might be using Image + Capture ?)

File + Print works differently when printing drawings and 3D parts/assemblies. Drawings are printed by processing the drawing to create actual plot data. 3D parts & assemblies are printed based on the screen image itself. If the screen resolution is poor, the print will be poor also.

To improve the quality, you might want to make the 3D as big as possible before you print it, Also, you might want to try different text fonts. Also, try changing the screen resolution on your computer settings.

If none of those provide the quality you want, you could make a drawing and use the ISO VIEW to project the 3D onto the drawing. Now you can change line types and line thicknesses and get good quality prints.
