Wipeout wipeout

Well I'm stumped again - that didn't take long.

Is there a way to add a Wipeout object using VL ActiveX functions?
If so, how? Or must one fall back to (command "WIPEOUT" ...) in order to
accomplish this?

(I am ultimately trying to define a block with the wipeout subentity first,
followed by more stuff 'on top')

I've searched the ng, without finding much other than via 'command'...

Any thoughts?

 

This is not a direct response to your query, but you should be aware that
wipeout does not work correctly all the time. There have been many users
reporting in these discussion groups that in using wipeout, there are problems
in printing, i.e., sometimes the frame is printed and sometimes the items that
were to be wiped out are printing.

 

WHAT! WIPEOUT DOESN'T WORK CORRECTLY ALL THE TIME?!
- yeah, I know they've had 'issues' - and I've had a few with them, myself.

I'm trying to define a simple detail bubble symbol with a wipeout 'behind' -
fwiw. In this particular case I think I'd be able to live with it not
working 100% of the time - as my *other* option would take yet more time
(manual trimming and/or excruciating re/positioning) - and *still* probably
wouldn't be complete 100% of the time, either. If a few things get missed -
well, so be it. I usually try to position the bubble in the least intrusive
manner, anyway - but sometimes it's not too easy to do, and that's where a
wipeout would be pretty handy.

And as for the frame printing - well, I've been using wipeouts with frames
visible (gads I hate trying to track down invisible things) but setting them
to an 'invisible ink' plot style in a .ctb. So far I ain't seen 'em -
except on screen.

I know I can store the block drawing in a folder, but I'd prefer to do this
programmatically, as it's 'cleaner' IMO. I really can't see any way to
create a wipeout other than via (command...) - but, though I haven't
attempted this yet, my idea is to create the wipeout that way, adjust it's
properties (plot style, color, etc.), then put it in a selection set, and
convert the selection set to an items collection. Then begin the block
definition via the 'Add method, and then copy in the wipeout via 'AddItems.
(This is the main part I'm not convinced will work - but I'll be quite happy
if it does.) Add the other 2 objects (a circle and lwpolyline). And -
finally - go back and erase the original wipeout.

Again, I haven't had a chance to try this - so I don't know if this will
even work. I'll post some code if (when) I get stuck - unless someone
already knows its hopeless and would mind informing me before I get too
banged up... Otherwise, off I go...

GERONIMO!

 

Dave:
I did a little research for you this am. Seems as though only the Copy method
is available, not Add. To learn more, create a WIPEOUT and do a
(vlax-dump-object Object 1) to see your available ActiveX properties/methods.

As to making WIPEOUT work better, I include "WIPEOUT.ARX" in my acad.rx file so
it's loaded every session.

 

Well... I guess we can *'ADD* ANOTHER ISSUE to the pile regarding these
stinkin' things! I thought wipeouts went 'native' in 2004. As if.

C'mon Autodesk! Grumble, grumble... ...and don't do anything to enhance
access to MLINES or MLINESTYLES EITHER by ANY means! Might as well throw
that in, while I'm stewing.

Crumb. Well, I got a little ways with the code, but looks like
(command -block ...) or the ilk will have to suffice - unless someone has
found a better way. I can't remember where I saw it, but I *thought* I saw
some code once wherein some tricky VL- method was used to convert or add a
selection set to a block object definition somehow - but after reviewing the
object model info in the help files, I don't see the means to do that. Ah
well.

Thanks anyway, John. Especially that dump-object tip - I hadn't seen that
before. So, not a total waste after all.

Best regards,

We should run a test to see how far we can insult adeslk before they pull a post.
They seem to ignore these threads.
I love how their ADN site has this like a big resource. The fact is you have to get lucky to get in contact with
someone at adesk who gives answers. I talked to a guy through the ADN and it was great. I had to totally complain to
get that call though. I feel their support for fixing bugs with existing autocad is overwhelmed and so its super
diluted. It makes serious acad usage an exercise in dumbing things down.
I run into some api bug on every serious program I write. Every single one!
The fact is most people treat acad like hand drafting on the computer and keep on upgrading so their version does not
become unsupported. Its too bad colleges do not teach decent cad skills.
Graduates do not realize their salary for the first two years at least is determined by cad skills.
The whole industry is still in transition but seems happy to pay ever increasing prices.
