Modelspace viewport count by activex ...

[Anonymous]

Has anyone else found the results bogus or unreliable?

(vla-get-count
(vla-get-viewports
(vla-get-activedocument
(vlax-get-acad-object)
)
)
)

I have a drawing with 4 modelspace vports; *NO* viewports in paperspace (
aside from paperspace itself ), yet the above code reports 27. I've toggled
the active space back and forth, re-opened the dwg. Done an audit / recover
etc. No change.

Other drawings correctly report the modelspace vport count.

Is it a flaky method or am I misinterpreting the results / failing to
understand the vla-get-viewports method ( collection of all
viewports in the drawing )?

PS: I initially encountered the problem using objectdbx, ie:

(vla-get-count
(vla-get-viewports DBXDOC)
)

but the same values ( one would hope ) are realized opening the dwg in the
editor and using

(vla-get-count
(vla-get-viewports
(vla-get-activedocument
(vlax-get-acad-object)
)
)
)

Thanks for any enlightening thoughts fellow lithpers.

Michael.

So what's new, yeah that's not the only screwy function.

Seems to be something missing...not your code.

Just so you know, I'm not trying to be funny, but doesn't seem everything is
running as smooth as it should.

They (Autodesk) wrote a disclaimer regarding the functions they found to be
flawed, leaving us the rest to find.

didn't test for long but here's what i noticed:

tilemode 1, vports from 1 to 4 - function returns 1 (last state)
tm 0 - function returns 4

so the function only returns the correct count when switching tilemode
(vanilla 2004 e-international)

same with saved viewport configurations.
tilemode 1 - vports saved & changed
after switching tilemode correct count of sum of all viewports (active
plus saved)

and: reliable so far (10 minutes ;-).

btw has nothing to do with LAYOUTREGENCTL

As much as I might enjoy jumping on the "bash Autodesk" wagon, it appears that
the dwg does have 27 vport objects:

I ran this:

(vlax-for viewport
(vla-get-viewports
(vla-get-activedocument
(vlax-get-acad-object)
)
)
(print
(vl-remove-if 'null
(mapcar
'(lambda (x) (if (member (car x) '(-1 0 5)) x))
(entget (vlax-vla-object->ename viewport))
)
)
)
)

and this was the result:

((-1 . ) (0 . "VPORT") (5 . "A1E2"))
((-1 . ) (0 . "VPORT") (5 . "A1E3"))
((-1 . ) (0 . "VPORT") (5 . "A1E4"))
((-1 . ) (0 . "VPORT") (5 . "A1E5"))
((-1 . ) (0 . "VPORT") (5 . "A1E6"))
((-1 . ) (0 . "VPORT") (5 . "A1E7"))
((-1 . ) (0 . "VPORT") (5 . "A1E8"))
((-1 . ) (0 . "VPORT") (5 . "A1E9"))
((-1 . ) (0 . "VPORT") (5 . "A1EA"))
((-1 . ) (0 . "VPORT") (5 . "A1EB"))
((-1 . ) (0 . "VPORT") (5 . "A1EC"))
((-1 . ) (0 . "VPORT") (5 . "A1ED"))
((-1 . ) (0 . "VPORT") (5 . "A1EE"))
((-1 . ) (0 . "VPORT") (5 . "A1EF"))
((-1 . ) (0 . "VPORT") (5 . "A1F0"))
((-1 . ) (0 . "VPORT") (5 . "A1F1"))
((-1 . ) (0 . "VPORT") (5 . "A1F2"))
((-1 . ) (0 . "VPORT") (5 . "A1F3"))
((-1 . ) (0 . "VPORT") (5 . "A1F4"))
((-1 . ) (0 . "VPORT") (5 . "A1F5"))
((-1 . ) (0 . "VPORT") (5 . "A1F6"))
((-1 . ) (0 . "VPORT") (5 . "A1F7"))
((-1 . ) (0 . "VPORT") (5 . "A1F8"))
((-1 . ) (0 . "VPORT") (5 . "BA6E"))
((-1 . ) (0 . "VPORT") (5 . "BA6F"))
((-1 . ) (0 . "VPORT") (5 . "BA70"))
((-1 . ) (0 . "VPORT") (5 . "BA71"))

Why there are 27 in the dwg when modelspace only sports 4 (and none in
paperspace) is a mystery at this point. Residual artifacts from earlier vport
command sequences?

Hmmmm ...

why not use: (vports)

So what you're saying is that there's 23 hidden vports or stored?

Michael,
Do you want the number of paperspace viewports? If so then
you don't want vla-get-viewports. Viewports are objects that
contain the view settings of vports in model space. Each saved
viewport configuration has a number of viewports associated with
it. The active viewport configuration also (I think) has a copy
of the viewports that have been saved. There is also a relationship
between layouts and model space viewports but I don't know
the specifics.
Does that help?

Also,

I run the -vports command and save the configuration to "test"

then...

(tblnext "vport" "test")
(setq vla_vport (vlax-ename->vla-object (tblobjname "vport" "test")))

(vla-delete vla_vport) <= but does not work....

Hi Doug,

What I'm trying to do is get the modelspace vport count.

But - your info helped. Lots. Said drawing has 12 named viewports in
modelspace ( including the *Active* Viewport, which sports 4 ).

Between all of the named viewports there are precisely 27 possible vports.

THANKS 🙂

( and thanks to Luis and Rudy who prompted me to think of other things too ).

Michael,

return the number of viewports in model:

(setvar "tilemode" 1)
(length (vports))

Oops, Ruul too 🙂

Look at the object model for more "good" info and you might
find this revealing:

(vlax-map-collection
(vla-get-viewports
(vla-get-activedocument
(vlax-get-acad-object)))
'vlax-dump-object)

While this may not be pretty it works ...

(setq Count 0)
(vlax-for vport (vla-get-viewports OBJDBX)
(if (eq "*ACTIVE" (strcase (vla-get-name vport)))
(setq Count (1+ Count))
)
)

I use 'vlax-dump-object quite extensively, it is most useful. Between it, the
object model map and my little atoms.vlx app there are not too many secrets 🙂

Thanks again Doug.

That seems the best technique. The current configuration is a
viewport and if split into other viewports, each viewport has
the same name, "*ACTIVE"....

You're welcome.
