[Sudhir]

Sorry

 

its a request

 

i dont know what is layer states manager so can u explain this topic also

[ReMark]

Sudhir:

 

I'm busy at the moment finishing up on my attributes document. In the meantime why not take a look at Lynn Allen's blog and the topic entitled "AutoCAD Gurus use Layer States". Page down past the photos of Jakarta until you see the heading. The link:

If you have further questions I would suggest posting them as a separate thread and not include them here. Thanks.

Hmmm...that's strange. I thought I posted part 3 about attributes but it appears to be MIA.

 

Well, let's try it again.

 

And now, without further ado (what is ado anyway?), here for your reading pleasure (or displeasure) is Working with Attributes - Part 3:

 

Working with attributes - Part 3.doc

 

Once again, additions, deletions and/or corrections are glady welcomed and appreciated. It's not as in-depth as I would like but I feel I'm too verbose as it is.

[Sudhir]

hey the documents which you have post is very use full for me

 

thanks for this

 

 

and also i have a new thread about layer status manager

 

if possible pls reply that new thread also

[ReMark]

You're welcome, Sudhir.

 

I'll have to check out your new thread. Personally, I do not use Layer States as we have so few layers in most of our drawings to begin with but I'll certainly look into the topic, read what may already have been posted, and try to fill in any blanks you may have about the subject. Sound like a plan?

[Sudhir]

Thank you

 

 

u have explained very well thank u

Ha ha, you want to get your invoice in ReMark, privert tuition don't come cheep.

I'm not sure my advice is worth enough to actually charge for. Usually when I try to put in my 2 cents worth the offer is declined.

Hi, sorry to bump this thread, but I thought it more worthwhile than creating a new one as my question is hopefully pretty simple really.

 

Well, it's more of a problem than a question really. I've been trying to get my head around attributes as I think it could be very useful. I'm a space planner and a while back we kept hearing talk of another programme (the name escapes me) that could compile lists of the products used in a drawing.

 

We didn't take it up as it had one major floor in its original incarnation and that was that if you used mirror to quickly duplicate a desk (thus ending up with a right handed and a left handed desk next to each other) the info wouldn't reflect this, so although you could see you had say 32 corner desks, you couldn't tell how many of them were right handed and how many were Left Handed.

 

 

Browsing the forum earlier I saw Lee Mac's Global Attribute Editor & Extractor and realised it might be able to do just this task. However I have never used Autolisp or Attributes before so I'm on new ground.

 

I don't expect you to explain the whole process for me, but my problem is this:

 

To get over the Right handed/ Left handed issue I thought I could just use dynamic blocks, with a visabilty state for LH/RH and an Attribute for each. I could then copy and flip (by changing visability state) to quickly create groups of desks. The changing visability state (as I see it will mean that if I had 8 desks set to right and 8 to left, a programme such as that above would see these correctly)

 

Will this work at all?

 

And also my test block wont show the attributes. They are within the block (can see in Bedit) but don't show in normal model space.

 

I've attached the block, sorry if this is very long winded, but I just want to know if I've got completely the wrong end of the stick before persuing this too far for no reason.

 

Thanks so much, I know some genius here will put me on the right track...

If there is no attribute for right or left, and it is just the state of visibility that indicates the orientation, how would that info be extracted? It doesn't seem possible to me.

 

Were your attributes set to be invisible?

 

What attributes should have been displayed?

[busseynova]

I had two seperate attributes - VPICD_L and VPICD_R for left and right. you can see them within the block editor. These were set just to show in the appropriate visibilty state, but your probablly right. At the very least, if the info could be extracted it would still just count both attributes I'm guessing, as one would be hidden, but still present, if that makes sense. You can see the attributes if you explode the block, they're not set to be invisible.

 

Can you think of any other way of doing it? As I say, it's not a matter of life and death, just seeing that LISP programme threw up some interesting questions in my mind about how the attributes system could be utilised in my work. Still coming back to this problem with the handing of mirrored blocks though.

 

I appreciate that if I just didn't use the mirror command then there wouldn't be a problem.

The attributes as you describe them above were not present when I exploded the block. I'm using plain AutoCAD 2010.

[busseynova]

If there is no attribute for right or left, and it is just the state of visibility that indicates the orientation, how would that info be extracted?

 

Eeeesh, I don't know TBH. I was hoping you could tell me.

 

Attached is the block exploded from the LH visability state. The attribute shows as the text at the top, not sure if this was properly associated with the block before. I think I'm gonna have to start at the start again and get my head around the basics of attributes before trying to get all dynamic block wizardry.
