Automatic Regen

[dbrblg]

Other than the FIELDEVAL command, is there any other way which can force a regen? 

What I would like is for a regen after a dynamic grip has been moved.....

Controls automatic regeneration of the drawing.
Type: Integer

Initial value: 1

Prevents automatic regeneration for commands (for example, when thawing layers)

1


Allows automatic regeneration for certain commands

The REGENAUTO command also controls this setting (not available in AutoCAD LT).

REGENMode is already set to 1 and REGENAUTO is ON.

Changing these dont seem to have made any difference.

Just making sure you know about REGEN

"...a regen after a dynamic grip has been moved..."

I assume you mean for this to be "automatic".  I don't know of any "setting" or option that would cause an automatic regen after manipulating a grip (in fact, I think this would be extremely annoying in most circumstances).

(Just curious, but why do want this behavior?)

Perhaps a simple strategy would be to create a toolbar button or define a mouse button or right-click button to run the REGEN command.

See Help for those subjects.

In my case, and I suspect there are many others too, I want to update a field in the block.

After I have moved the grip I want the value displayed to be accurate ie what position the grip is now.  I could have the situation where the user has not regen'ned after changing the grip and the previous value is displayed which could be a costly mistake. 

Would be good if as part of the actions / parameters of a dynamic block contained pre/post triggers to attach .net (or lisp at least) scripts.

"In my case, and I suspect there are many others too, I want to update a field in the block."

Yes, now I see. Thank you.

A modification to the FIELDEVAL variable, in the form of a new setting to "update on grip-edit" (assuming that's feasible), would do the trick.

"Would be good if as part of the actions / parameters of a dynamic block contained pre/post triggers to attach .net (or lisp at least) scripts."

Yes. Or simply the ability to assign a basic AutoCAD command as a sort of "chain action".

Totaly agree.

This is must have feature. I have to manually regen fields after changing grips in my dynblocks and if I forget, this might cause a serious mistake.

Of course not. That's not what REGENAUTO is for.

Just want to clear that up for future readers of this thread.

REGANAUTO is to *prevent* automatic regens from occurring when OFF.

It's purpose is not to cause additional regens to occur when ON.

How so?

Even with REGENAUTO turned off, as long as FIELDEVAL is set correctly (31), the drawing will regen each time it's opened or plotted.

You may be able to define a reactor (editor or object?) that can capture the moment your dynamic block is modified, then fire the REGEN command automatically.

You can define a reactor to keep FIELDEVAL (and/or any other sysvar) from being modified.

[dbrblg]

I think the point here is that the ideal situation for us is to have the drawing or block regen when a grip is moved.  Even with FIELDEVAL set to 31, the drawing or block wont automatically regen when a grip is moved or repositioned because the drawing hasn't been opened, saved, plotted or regen'd. 

Even if the drawing or block cannot automatically be regen'd, an alternative would be for fields within a dynamic block to automatically update when grips are repositioned which is really what this is all about.

The second to last post on this page contains code to create a reactor that WILL regen upon a grip edit stretch.

For your grip editing pleasure.....

Very interesting, thanks for this

Thank you for the link to the reactor.

I've never heard about it before. I got the meaning, but failed to get it working.

I've loaded the lisp:

(defun ss->lst ( ss flag / id lst )
(repeat (setq id (sslength ss))
(
(lambda ( name )
(setq lst
(cons
(if flag (vlax-ename->vla-object name)
name
)lst
)
)
)(ssname ss (setq id (1- id)))
)
)
)

(vlr-command-reactor "FieldUpdate"
(list (cons :vlr-CommandEnded 'Regen))
)


(defun Regen ( react data / ss )
(cond
( (and (equal data '("GRIP_STRETCH"))
(setq ss (ss->lst (ssget "_p") t))
(vl-position "airspace"
(mapcar (function vla-get-effectivename)
(vl-remove-if-not
(function 
(lambda ( x )
(vlax-property-available-p x 'EffectiveName)
)
)ss
)
)
)
)
(vlax-invoke 
(vlax-get (vlax-get-acad-object) 'ActiveDocument)
'Regen acActiveViewport
)
)
)
(princ)
)

And I was hoping it will auto trigger when I use any grips (at the moment I am using stretch and visibility change grips). But nothing happens, fields do not update.

I would really appreciate some help.

I would also like to know how to implement this lisp/reactor to work with the fields in my blocks. I have field attributes that are tied to lookup tables in my block. I would like for a "regen" to occur each time that a selection is made on the lookup table so that the attribute will seamlessly update with the selection made on the lookup table. 

I have attached an example file that contains two of my more complicated blocks. The attributes that I'd like to update are circled in the file. Just click on the block and make a selection from the lookup table and then "regen" to see the change.

Maybe what people try to do with an AUTO REGEN is the same as Using VIEWRES with fast zooms and 20000 value.

@mantsoft hi,

Are aware that this thread is seven years old?

[mantsoft]

yes

7 years after Im looking for the same answer...  Im not the only one for sure.
