Let's wake this discussion up again. @bobkoll @davew have reported that there is a problem with the current Picture command.
The workflow that is best for John Niebergal and other teachers is to use BackGroundBitmap Attach.
Therefore you can have the image visible in only one viewpot. And not in another.
A solution for them would be to have a "hide in viewport" and "show in viewport" for a model viewport.
Using layouts as a workaround is too complicated to be a good option.)
1. @dale Is this possible to have a "hide in viewport" and "show in viewport" for a model viewport?
2. @pascal Should it be added to only work for a Picture, not a curve, surface or solid, for example.
3. Or is there a better idea?
"While at the Kelso workshop John N. used background bitmap to trace an image . I suggested that pictureframe was better as you have more control over the image (visibility, scaling , ETC,)
John said bitmap had an advantage because you could have the bitmap show in one view port and not the other by having two TOP VEWs.
John uses Background Bitmap ONLY. Many teachers/students learning this skill each day. If Background Bitmap is going to be part of Rhino in V6 and beyond, I don't see an issue.
It would be nice to be able to control Pic Frame visibility per viewport. [maybe already available in Rhino without creating a Layout; show us]
How difficult would it be to have a hide in view (similar to Hide in detail command) I could see where it would be nice to have items hid in a view yet visible in another for comparison and alignment value as well as when tracing an image."
