AutoCAD Dynamic Blocks :: Field Value Not Updating Attribute Value
Jan 29, 2013
I have created a rectangle whose length changes.The value of the paameter "Dist1" is this length field that I associate to the attribute value. Basically, echo length from Dist1 into the attrib value.
The problem is when I insert the block into the drawing the value is shown as "DIST1", even after regen.
Once I pull the grip point to a new length and regen it still shows "DIST1".
If I go into the ddedit and select the edit box (for multiline data field) the shown value will correct itself, but only one time.
If I change the length again, the dimension does not update.
It worked fine when I tested the block but is having issues days later.

Attached is my latest block that I'm working on. how to keep a field readable (horizontal) when rotated. What I need to do to update a field that is linked to an attribute when the attribute value is changed? The UPDATEFIELD command does not seem to work on it for me.

Fairly versed with Dynamic blocks here, so the first thing I checked was to make sure that my FIELDEVAL was set to 31 to ensure updates but this one isn't working for me and may be a limitation of the software?
I'm making a dynamic block for my users who aren't familiar with electrical wiring so I am developing a series of blocks for our typical wiring configurations. In this instance, I've setup a pair of attributes to allow the changing of wire color codes and I want to use that single attribute entry to used in multiple other locations that are also connected to that conductor in certain situations. I have setup a field within this block to be the "VALUE" of the object (the attribute) in order to accomplish this. Unfortunately it is only displaying the default value I have for the attribute and will not update either upon insertion of the block or after an edit. Is this beyond the capabilities of Dynamic blocks or do I need to take a different approach?
Find file attached.

I've got hundreds of files to convert.
In VBA, how can I batch convert field attributes in blocks to text attributes while retaining the blocks? Is there a simple way to univerally convert them all at onceusing VBA? The plotted values for the fields must be retained, too.
Explode will not retain the value of the field.
Burst will not work as it explodes the blocks as well.
You can right-click on the field and slelct "Convert to text" from the RCM. So I know that the process exists within CAD, just need to batch the process for a quantity of DWGs at a time - in VBA.

How do I manipulate a height parameter all of the dynamic blocks in the drawing from one single field? Say a field located in the drawing properties or on the drawing itself.
For example: Multiple blocks of different walls of same height with other blocks of things on located on those walls, dependant on the wall height, all linked to and changed by a single field. Possibly a Wall Height field located in the custom tab of the drawing properties.
I can pickout each of the blocks and change them at the same time in properites menu because they all share the same parameter name. I would just like to have that height parameter of every block in the drawing, that has that specific parameter controled by a single field. Which I could enter a new height at anytime that would change every block in the drawing to that height.

I wish to create a dynamic block containing some attributes. These attributes are inside rectangles that can't be modified in length using linear parameters ; but the attribute has to be always in the middle of the rectangle. So, I draw a line inside the rectangle (in a hidden layer) and insert the attribute with center justification (not sure for the translation) that I place in the middle of this line ; then I put a coincidence constraint (not sure for the translation, but it's the first one) linking the middle of the line with the middle of the attribute.
But here's the problem : when stretching my rectangle, the insertion point of the attribute suddenly changes from "center" to "bottom left".

I am looking for a way to use the ATTIN/ATTOUT workflow to bring in data from an excel spreadsheet to drive the size of each of my block's instances. The block will be simple, a rectangle, with width and length parameters. For each entity in my excel/csv file these parameter values are spelled out. I know how to display these parameters in my attributes, but I don't know how, if I were to feed in these values, to drive the geometry. If there's a better way to take a list of width and length values to generate a series of blocks each with a rectangle containing its respective size.

I have the same block repeated multiple times in a drawing, and I want to delete the last attribute in all of the specific blocks. When I edit the block in block editor, the attributes do not show up. After I explode the block, there is no text. The attached image shows the properties of the block.

I have a dynamic block.
It has length and width stretch actions activated by grips. (Works fine).
It has an attribute for the user to type in a height value. (attribute insert box appears on block insert and when double clicking block).
It has Mtext "worktop [field] High" the [field] is looking at the attribute value so in theory should return the value the user types. But no only ---- shows. regen/regenall/battman fieldeval 31
Am I missing something i have pointed the field to tag/prompt as test and they show up in the mtext.

I have a dynamic flat screen tv block. Its length flexes to match the lookup table chosen size...32" 42" (the length parameter being a defined mm length) etc i want to display the 32" 42" etc items from the lookup properties table, but i'm at a loss as to how to go about it.
currently i am using an attribute with a field pointing to lookup parameter/object/lookup description string but it's returning hashes.

I'm following this tutorial, trying to create a field in a dynamic block to show the length of a line. If I have the attribute's "constant" value checked, the field shows up in my drawing as "Length: ######." However, when I uncheck the "constant" checkbox, the field doesn't show up at all, even after I run "UPDATEFIELD" and "REGEN."
I'm using AutoCAD Mechanical 2009, SP2.

Change the 24 x 24 x 12 MLeader in this Block to Fields that read the length of the Lines that the Distance1 and Distance2 Parameters are attached to and tell me if it crashes? And if it does not crash, post a working DynBlk.

I am having trouble getting a field in a multi leader which is part of a block to reference a sheet set custom property. I have fields within mtext in paper space that are not blocked that are referencing correctly but just not in my blocks.

I'm working in AutoCAD 2010 and I would like to make the process of creating 2D documentation easier and faster for myself and my collegues, but during the process I've hit a dead end.
I would like to use fiedds (or something simillar) to partly automate the creation of 2D documentation. We have sheets organized in a specific way and I would like to create a custom field for each of the categories (eg. drawing number, number of parts, designer...) that could be edited easily like the parameters or object properties can. Basically what I would like to do is create custom fields or some other object that can be edited from a list in AutoCAD and then automatically refreshed in text boxes. Is there a possibility to do something like that using fields or perhaps a different solution?

I am unsure weather to post this in Dyn Block technical or Fields as it comprises elements of both.
I am trying to get a field to return a 'lookup properties' value...
Actually, what I am trying to do is use a field to display either a + or a - depending upon upon the state of a flip parameter.
How I have been trying to achieve that is by using a lookup table to assign:
Input Properties.....Lookup Properties
Not flipped........=............+
Flipped.............=............-
Then I'm setting a Field to look at the Object 'Lookup Parameter' and return 'Lookup Action'.
The field then displays '#########' when testing the block.
When I return to edit the field it complains 'the object referenced y the field has been erased'. Both the table and parameter are still there, so I don't know what the problem is. Is there a better way of having a field return a specific value based upon a parameter state?

I have an attribute definition and I need to add its value to an mtext. I added it in mtext insert field it is ok, every thinks work fine it is only needs a regen but it is not a problem.
The problem is when my mtext and att in a block regen does not work in model space, I had to enter block and regen. Is there any way to do it without entrance in block editor?
I attached a simple example.

How do you edit attribute tags (only) and retain the values of the attributes? When I try to redefine a block the attribute values change with ATTSYNC.

I need a rectangle block which on insertion prompts me for some data (name/tag/item number) and then displays it (this I can do). This is al pretty straightforward. But I also want to be able to fill in width and height and then have the block stretch to the correct size. So basically what I think I need is to have the value of a parameter refer to the value of an attribute. I've gotten it to work the other way around, where the attribute displays the size of one side of the rectangle (after stretching and regenerating), but I'd really like to have it working the other way.

I've created a dynamic block with two visibility states. The second state is a copy of the first state, but some of the attribute definitions have been moved, along with some of the geometry.
When I insert the block, then toggle between the two visibility states, the geometry changes as I would expect, but the attributes stay in the position dictated on the first state.
How can I make sure that the attributes move for the second state, as I need them to.

making dynamics blocks and more over utilizing the attribute feature but I have discovered some chnages tat i need to make.
My question right now is, once an attribute is created and put into the block editor is that it? Ifi need to edit it can i edit it? I don't really see an option or command right off that would allow me to do this ?

I am trying to set constraints to this block and having some issues. I want to constrain the attribute text so when I stretch the block from the grips the text centers itself automatically within itself. The constraints will not let me pick the grip on the attribute text as a point.

I've built this nifty block for holdowns, but the attributes get all goofy on me when I use the flip command. The problem is that the justification of the attributes does not change when they are flipped - so if I modify the text in the attribute while the block is in the FLIPPED state, how to modify the justification?Check out the attached file to see what I'm talking about. The block instances are numbered so you can follow along:
1. block is inserted
2. attribute text is modified in NOT FLIPPED state - everything is dandy
3. block is flipped
4. attribute text is modified in FLIPPED state - text justification is jacked up
5. block is flipped again, in order to demonstrate the continued jacked-uppedness of the attribute

What I'm trying to do is have a graphic scale with a set list of scales the user can pick from. This was easy using the Visibility Parameter.
However, I want to add a "custom" vis state where, once they select this option, the attributed definition box will pop up and give them the option to input whatever scale they are using.Check out the attached .dwg to see what I've done so far (I just have the attributes on the "custom" vis state).

I need to create a small table to ID the User, Computer name, Door Key, etc for a floor plan drawing of our office. I'd like to get this done in Excel and link it all so the bldg manager can make changes to the drawing without me. I have created the excel file and created a "name set" in excel for each room. In Autocad 2013 I have inserted a table from a data link and pointed that link to the named range of the room (the named range in excel is an 8 cel block with al the info I need repeated and uniquely named for each room.
This works great...so my next step is to create a block out of the table and make the DATA LINK a variable attribute...that's where I'm stuck. i cannot figure out how to do this. I would love to be able to INSERT BLOCK and have one attribute question...ROOM NUMBER?. That should look to the excel NAMED SET the corresponds and populate the table.

I have two visibility states. STATE1 and STATE2 used at attribute .
I only see the first (STATE1) or the default.
Changing the state works fine with objects ( a simple box and circle) but not with the attribute.

Attached is a dynamic block for a civil grid tick. It's my first time creating a dynamic block so it's probably not the most efficent use of the dynamic parameters etc.
I have it setup with 4 visibility states to allow the northing and easting attributes to "rotate" about the center of the grid tick, to give options for readablity and/or text overlap.
What I wanted to add was figure out how to make the individual attributes flip 180 degrees about a point (roughly the center of the attribute). Again this would be for readability.

Attached is a block that I use a lot. Originally I had two separate single line text attributes for the "title". I modified it to have a single multiline text attribute instead. I want this attributes text box width to stretch along with the line below it, so that long text strings will automatically adjust to single or multiple lines as necessary and not run off the end of the line. As it stands now I have to stretch the line and then adjust the width of the text box to match.
Also it would be nice if the bulk of the text would stay on the bottom line and only the "overflow" would move up to the next line.

I am very new to dynamic blocks. I am starting off learning the small stuff before I get to the larger more complex blocks to convert to dynamic.
I have a reference block I am trying to "master" all the functions we would like to see.
I have two major concerns.
1) Why can't I rotate this block (via rotate action) and have the attributes stay at angle zero? I thought I built the parameters and actions correct.
2) I haven't ran across anything that explains how to stretch 2 linear parameters at the same time with the same distance (ex: stretch both at .25, .5, .75)
