Topic: Invisible viewport

[bbarron281]

I wasn't the original author of this CAD file. I was wrong about creating a new viewport to avoid this problem. The new one that I just created is invisible too. It's on its own "viewport" layer which is on and thawed. The color of the layer is different from the background color which is black. I created the viewport by drawing a polygon so I know it's not bigger than what's viewable on screen. Still stumped. I feel like you might know the solution, ronjonp.

Can you post your drawing ? Also .. try the code I posted in my previous response.

I don't feel comfortable posting the drawing...work related stuff, you know. Let me know if I ran the code right. I copied it to notepad, saved it as .lsp, appload in autocad, executed "foo" command.

I have limited experience in lisp routines so I think it's likely I missed or messed up a step. But after the command nothing changed, not in respect to the invisibility of the viewport anyway.

save the file with a NEW NAME

ERASE everything other than the SICK Viewport.....easy enough to remove ALL TRACE of who, or what the file is about.

Or don't you want this resolved?

[bbarron281]

Here's a stripped down version. There are two viewports. One can be seen in the bottom and the one above it is invisible.

Code: [Select]

Command: (defun c:foo ( / i )
(_>      (repeat (setq i (sslength (ssget "_x" '((0 . "viewport")))))
((_>        (vlax-put (vlax-ename->vla-object (ssname ss (setq i (1- i))))
'visible -1)
((_>      )
(_>      (princ)
(_>     )
C:FOO

Command: foo
; error: bad argument type: lselsetp nil

That's what happens when I don't test it

Code - Auto/Visual Lisp: [Select]

1. (defun c:foo (/ i ss)
2.   (setq ss (ssget "_x" '((0 . "viewport"))))
3.   (repeat (setq i (sslength ss))
4.     (vlax-put (vlax-ename->vla-object (ssname ss (setq i (1- i)))) 'visible -1)
5.   )
6.   (princ)
7. )

Although it does not fix the OP drawing.

time to delete that particular viewport and move on

[bbarron281]

Already have. This error has reoccurred with the new viewport that I created as well. The explanation I will get from my supervisor is that it's an error in the drawing. This seems like a bit of a cop-out explanation to me but that's probably because I'm stubborn and want a reason for everything. I'll figure out a way around it though. Thanks for the help, everyone.

Even when I'm clicked into the viewport, zoom moves paperspace.

[mjfarrell]

Bethrine; your issue is the viewport is LOCKED a good thing.


bbarron281

This worked here

I wblocked/deleted the viewport into a new dwg
it opens and knows it is still a viewport yet it displays
then copied with basepoint
and pasted back to original coordinates in your sample file
it displays and is a viewport once again

now trying to solve WHAT happened to it....to start the issue off

[Bethrine]

Bethrine; your issue is the viewport is LOCKED a good thing.

Ah.   

[bbarron281]

mjfarrell, I've taken the file I provided and qselected the viewport then did the wblock command with a base point. Then in the drawing I'm working with I've run the insert command to the exact base point but I'm not getting anything. I've missed a step here. I rarely use the wblock command so I bet I messed it up.

Looks like someone drew a rectangle, used the VPCLIP command to modify an existing viewport to then use the newly created rectangle, then the rectangle was deleted leaving behind the viewport. I don't know of any way to recreate the viewport outline without some sort of programming wizardry.
