Controlling the length of arcs within the RevCloud command

[mom of 3]

ok, I give up on this whole search forum thing.........
isn't there something to change the arc of a revision cloud so that it stays constant at the value I initially enter? example - I do the revcloud command, I get the arc length/object option. I change the arc length, but when I go to draw the next cloud, I have to go through that again!!!!!!!!! ideas???????? I'm on ACAD 2004...........
thanks!

Without really looking into it, what you need to do is change the arc length variable (ARC_LENGTH) from local to global. Ideally, you should probably write in a check to see if it is already defined and set it to a default if it isn't. If all that sounds like jibberish I can try to walk you through it.

Okay, I looked into it quickly and now I'm confused. When I use revcloud (which is practically never) it saves the variable as it is. Just change it in the options window and it works each time. Maybe I'm not getting the question.

Hi

RevCloud Arc length is associated with the current DimScale, below snippets come from the AutoCAD Online Help File [F1] -

<snip>
REVCLOUD stores the last used arc length as a multiple of the DIMSCALE system variable to provide consistency among drawings with different scale factors.

<snip>
Note REVCLOUD stores the last used arc length in the system registry. This value is multiplied by DIMSCALE to provide consistency when the program is used with drawings that have different scale factors.

Have a good one, Mike

Mike- That doesn't explain why it would change in between every use unless she's in the habit of changing dimstyle every time. Even then, if dimstyle has changed, she wouldn't get the desired result by re-entering the same arc chord length as before -she would have to compensate for the difference. It sounds to me like that's not what is happening.

Hi

Check out the following thread from the Autodesk Discussions Groups -

now you've all confused me, but I think I partially understand the dimstyle deal. I guess I'm wondering why my option won't stay after I've changed it on my first revision cloud, like Simon was saying that it should? I haven't done anything with the dimstyle.......

Wow, look's like -once again- Mike's found the obscure answer. I never would have picked up on that one.
Okay, what they're saying in the thread is that there's a problem in the way the program is written that causes it to forget your previous size setting if the setting is higher than a certain point. Beyond that point, the program misreads its own variable and returns to the default. I'm guessing that what's confusing you is that when they're talking about arc size they don't mean the chord length that you entered, but the resulting length after it's been scaled. I hope that helps explain it.

so basically, since it's trying to read off the dimstyle (which still doesn't make sense), I have no way of changing it to the constant that I want it to be? I'm just stuck changing it every time, then.......ok.
