an old dog needs a new trick

Jim Yadon:
This was originally written before the 'Garden Path' tutorial was made available to me. I am sure there is a much more elegant way to go about this. The layer control calls will need to be commented out prior to anyone trying to use this.

I already have some ideas for refining a few things but I wanted to submit it for speculation by you wizards before proceeding with any more changes.

I seem to be missing the finer points on a few things with LISP so here is a list of what I am lacking the skill to handle -

* passing variables between subroutines
* handling and escape form the command
* ghosting of the viewport outline for placement in paper space
* some other functionality of LISP I could use to accomplish this?
Once complete, I already have a menu, tool bar & pallette that go with the code that I can post in our collection.

edit by JAY - commented out the layer control code that could cause a burp

Jim Yadon:
:? hmmm... no takers?

T.Willey:
How much are you planning on rewriting? and how much to you want to simplify calls? I can help tomorrow, or maybe tonight, but I don't have cad at home so I can't test anything.

ronjonp:
You will also need to include all of your subroutines. I do not see (viewport_layer) in your post.

I commented out the view port layer routine in the code example. That's a legacy item that is called and some of the code is not mine to post.

I am actually going to integrate a windowing feature that allows for selection of the window from any crossing points rather than the lower-left to upper-right that it's set up for. I am really looking for some ideas from you guys how to improve what's there while keeping that basic command call structure intact. I currently have somewhere in the neighborhood of 75 people using this and don't want to break other things that link to it.
