Topic: Invisible viewport

[bbarron281]

I think this is my first time posting here. My problem involves a viewport that I cannot see the boundaries to. All layers are thawed and on, frame value is set to 3 (I don't know how because it says from 0-2). I can select the viewport by using the qselect command but even when I have it selected I cannot see the selection. I can, however, edit the attributes of said viewport in properties. I can easily just add another viewport to avoid this problem, I suppose, but I was wondering if anyone knew why I couldn't see it. Any help is appreciated. Thanks in advance.

be sure all layers are ON and THAWED
perform a regen

and perhaps place your VIEWPORTS on a unique VIEWPORTS layer to control them better

My guess is that it is the same color as your background.

If you could post a file exhibiting the behaviour, we could bypass the guessing.

the guessing is the fun part of this

My guess 

VP is so large it is outside your current view.
Zoom Extents perhaps?

What bit me one time is that I had the Light on, Thaw on, but the 'freeze and thaw in current viewport' option in my 'Layers' Toolbar.

You mean like this ?

Okay, I'll bite. How did you do that?

I'm Stumped so far.

I am going to ignore the rest of the responses in this topic until Monday to see if I can figure it out over the w/e.

That explanation is above my head. Is there a layman's way to do/undo it?

[mjfarrell]

vla-put-invisible 

I would think that would 'only' work for block attributes?    hmmmmm

That's what I got out of it, too, but "apparently" not the case.

Like this, yes.

Wrong link LOL .. updated above. vla-put-visible NOT vla-put-invisible.


See if this fixes it:

Code - Auto/Visual Lisp: [Select]

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