My boss gave me a copy of Autocad 2012. I've messed around with architecture 2010 before so the ribbons are no surprise. One thing I have noticed that's really different is the dynamic block constraints & block table actionblock properties table? I looks very similar to the lookup property table
View 0 RepliesSo I'm creating a block with a block table and constraints. The constraints such as Geometric Constraints work just as assumed. When adding in dimensional constraints we start to have more fun. So I have dimensional constraints that use other dimensional constraints to manipulate itself.
EX. dimconC = (dimconB-dimconA)
dimconA is 12
dimconB is 14
dimconC would be 2
Now when ever dimconA or dimconB change dimconC would populate accordingly.
With this I wanted to make an attribute that could be placed in instead of a dimensional constant.
EX dimconC = ((Att1*dimconB)-dimconA)
Att1 is 02
dimconA is 12
dimconB is 14
dimconC would be 16
However when trying to place in formula that references a attribute I keep getting an error "A DEPENDENT EXPRESSION CANNOT BE EVALUATED" So I assumed it was missing an expression from the attribute, however once entering an expression in for it I still get the same error.

Is this something that is not allowed at all or have I over looked something?
I am in the process of fixing one of our dynamic blocks. It's a fairly simple fix where there was a typo in one of the names of our items in the lookup that needed to be fixed.
I changed the name of the item in the lookup table. I went and did the test block and it seemed to work fine, but when I bring the block into a drawing, it reverts back to the old lookup as if I did nothing at all.
I made sure that the path was correct and I even just dragged and dropped straight from Windows Explorer to no avail.Does AutoCAD keep referring to the old block? Did I forget to change something else?
It's about "Block Properties Table",I want to use a Block Properties Table to manage a Dynamic Block.
I have defined a Dynamic Block a and its Block Properties Table in Autocad2010,this is the screenshot of the Block Properties Table(a1:d1=100,d2=200;a2:d1=100,d2=400;a3:d1=100,d2=600.) Now I want to insert the Dynamic Block using .NET API.after I input a command,the block of a2(d1=100,d2=400) is inserted. I have the code about it, but the code is not complete. this is the Dynamic Block
this is the the screenshot of the Block Properties Table .
the result:
the code about it:
[CommandMethod("readBlockTable")]
static public void CmdReadBlockTable()
{
Editor ed = Application.DocumentManager.
MdiActiveDocument.Editor;
// select a block reference
[Code].......
The attached image shows a block of a speed ramp. I have a linear parameter in the middle of the block to stretch the block. When I stretch the block I want the triangles to be evenly spaced. I have setup constraints as shown. They are all linked back to d6 but d6 is locked. How do I unlock it so that it changes and the dims update?
View 9 Replies View RelatedI created a block (Attached).
Is there a Geometric Constraint that can keep the two lines (red and green) keep touching the blue one and look like the drawing right below the block that is Exploded?
is there a way to make a dynamic block that adapt when using with constrait...i want the block, wich will be a panel with different visibility, to adapt between 2 geometry using coincidence or colinar constraints
so when i change the parameter of the distance between the 2 geometry , the block length will ajust accordingly i'm not new to the dynamic block but to using parameters with it, never done that.
I am trying to create a dynamic block that represents a cable with an attribute attached. The block is essentially a line that runs along the Y axis. I have created a distance parameter with a stretch action attached. The line is to remain anchored at the top and the bottom end is permitted to stretch.
Problem: I have an attribute inserted to the left side of the line (offset at -2mm TC insertion) at a rotation angle of 270. When I select the stretch grip (in the drawing environment) I would like the attribute to remain centered with the line maintain the offset and maintaining the rotation angle. I have exhausted all of my options (limited experience).
So I've done a reasonable amount of work with dynamic blocks. I have a block with a rotation action and grip to arbitrarily align it. However I realized when trying to combine it with an alignment grip (which actions on the basic or fundamental block rotation angle) that there didn't seem to be a way to some how link a dynamic block rotation action or one of the custom angle properties to a the fundamental block rotation angle. Thus there are two additive rotations at work; the dynamic block one with its grip and the fundamental rotation property.
This can cause some confusion when one person aligns with the grip and another via rotating the block's fundamental property and would also be problematic in the generalized sense if one was trying to select or programmatically read back the net angle alignment.
I'm working on a drawing and I want an action to work on two diffrent dynamic blocks.
In my case, I wish to have two blocks that I can rotate by one rotation grip.
How do I manage to work this out?
I have a dynamic block, that represents a stirrup.
I inserted in the block a Block Propreties Table, that have some preset dimensions for the stirrups. The grip of this table I decided to put in the top right corner.
The problem is that I can't make this grip moveable )
See the attachement with the block
Basically, I have a dynamic block with a distance parameter attached to an array command. The array command has a column distance of 30 inches between columns. I need to edit that distance. Is there a way to do it or do I have to start over? I have to start over, I might cry a little bit. There are a lot of other actions compounded on top of this one.
I'll attach the file, but if you edit it for me, how you did it so I'll know? Tech a man to fish and all that nonsense.
Oh, and I'm using 2012 vanilla AC, which has a different block editor than most other versions, so beware. Oh, and I don't use ribbons..
Ok over the past few weeks I've got pretty much most of the Dynamic Block stuff down except this feature.
I've attached a drawing. In the middle I used VISIBILITY to have all the different weld types. I need something at the end to where Weld Tails can be added if they're needed but you can only use one Visibility per block. I'm also going to need something at the front of the block for different symbols like "Field Weld" and "All Available". If I can figure the Tails out then I can do the other one.
I've created this dynamic block for work. Its an overhead cupboard with 4 doors. My problem is that when i create a table through data extraction the value for the length and height for the doors aren't shown (The column this there with a heading, no value), the length of the cabinet and visibility is though. Do i need to assign an action or something for the value to be displayed?
View 6 Replies View RelatedIn my Project I build a static Block by inserting dynamic blocks from a template dwg and then explode them.
Actually I create a new Data Base, insert the blocks from my template, set the according Dynamic Properties, Explode the Block in the temp DB and then wblockclone the resulting Objects in my destination BlockTableRecord.
This works fine, but:
in my source dyn. block there is an associative surface defined by a Polyline(Rectangle) , attached a stretch action to change the size. I can set the Width parameter, after the Explode the polyline itself is updated, but the planar surface is not... so if I explode this block I get a well stretched Polyline and the "base" surface.
Manipulating the dynamic Block works fine... If I have stretched 3D-Meshes, they are ok as well. It seems to be something with the planar surface object.

I am attaching a rotate parameter and action to a dynamic block.
I get the "Specify base point" bit okay but I can't figure out what "Specify radius of parameter" does.
Do I have to include or exclude other parameters like Flip or Stretch? I get some weird results when I rotate an object with other parameters.
Is it possible to place the Grip in a specific place? It always seems to like to sit on top of another parameter name.
Is there a trick in using a dynamic block in a table cell? When a dynamic block is inserted into a cell, any visibility can be viewed (Properties Manager) in that cell if the visibility state has a block in it. What happens if the visibility state does not have a block. That is, if the view has exploded block so one can use parts in actions etc? Can I view ANY state in a cell regardless if it has a block or not? Or must the visibility states have blocks to be able to use it in the table cell?
View 2 Replies View RelatedI have created a dynamic block and have applied some lookup tables to it but its not working just the way I want it. I think its to do with the custom entry on the lookup tables. If I delete the custom entry when i select the block in model space the drop down select box to allow me choose a selection is no longer available. How can I remove the custom entry and still have the block working normally. I've attached the block.
View 9 Replies View RelatedI've created a titleblock with a menu to select sheet size, a single set of attributes that serve all the different sheets, but now I'm trying to find a way to add a table.
The table is to sit above the title box and include information on: New revision number
Text detailing changes since the last revision (might be single or multiple line text)
Date of new revision . The bottom line needs to sit flush to the top of the title block so the top line would be moving up the sheet as new lines are added if that makes sense?
I am attaching my dynamic block that I am having difficulty finalizing. My goal is to be able to stretch or resize the hvac block, based on the size that is provided to me (ala 24x24, 36x36, 48x72, etc) (Stretch Action), I have that figured out, and I have the symbol in the center that stays centered as the block size changes, (Move Action).
Here is my problem, I want the symbol in the center to stay centered and scale based on a ratio as the overall size gets larger. So for example: if my size is a 24"x24" I want the symbol in the center to be approx 12" dia, but if the size gets up to say 60"x60" I want it to scale accordingly (so it could be like 48" dia), specifically maintaining the size based on the x axis, so if the it gets to a 60x72", I'd like it to still be centered but size according to the 60 width, and not stretch and look awkward. I want the center symbol to scale and stay centered in the rectangle as I scale the size.
I use dynamic blocks a lot of the time and most of them have a stretch action in them. What used to happen would be that whenever I clicked on the block I wanted to adjust and then clicked on the stretch action, it would show the distance from the base point and I was able to type in the new length of the object I was stretching. But now whenever I click on the stretch action, it shows that the current length is 0 and it is asking for the distance from the current point, not the base point. How can I change it so that it is always just the distance from the base point?

View 1 Replies View RelatedI have this simple dynamic block that is to change from 4" to 6" to 8" square. I have a linear parameter, 0 grips, and a Lookup function for 4, 6 or 8. It is supposed to scale about the midpoint (insertion point). I have tried both the Midpoint and Startpoint settings for Base Location but it always seems to scale from the far left of the Linear Parameter.

View 5 Replies View RelatedI am creating some table of contents. The first column contains symbols that are inserted blocks. Now, when I've created dynamic blocks I've made them to have more visibility states. If I insert the block that has such states, only the saved state is visible. Is there any way that I can use more visibility states when inserting some block into table.
At the moment the only solution is to insert another simplified block that I've created just for this insertion. That way my blocks library is getting bigger and bigger only because of this. I don't use simplified blocks in my drawings, except for the thingy mentioned above.
I am having some troubles whit my dynamic blocks.
Whenever I add a block property table the window that should be opent doesn't open. The strange thing is that I think it actualy is open but i just don't see it on my screen. The same thing gous for the screen that allows you to ad a parameter to a lookup set. by folowing this link you can see what i mean, it gets interesting after 30 seconds.

I have a new project coming up where I need to write some simple programs to access the dynamic action parameters in some existing dynamic blocks.I have viewed what I could find on AU, but I still ave not found anything relating in-depth to dynamic blocks.
Any good Tutorials, Articles, or White Papers, on working with dynamic blocks with autolisp/ vlisp? The main function is to access a parameter and change it by entering a numeric value, updating the block. say from a linear/polar stretch, or a linear/ polar move.
i was wondering if it's possible to change the default precision of values in the drop down menu for linear parameters when using a block properties table from 4 digits to 0.
See attached file, when opening the dropdown menu, the centre-to-centre widths of the chair are displayed in a value with 4 digits "behind the comma" and i would like that to be 0.
We use a number of blocks with block tables for data extraction here, and whenever one of the blocks is modified and updated, all of the block tables reset to the default value. This happens for any block reference change, not just changes to the block table (which makes sense that it would reset).
How can we update these blocks without having to manually change all of the block tables afterwards?
What are all the block table records?
I've got Model Space & Paper Space(Or Layout Space) under control.
I've got two block reference instances of the same block on a drawing.
If I purge the Drawing the older duplicate block reference disappears.
7867 is the older reference that disappears when I use the purge command.
78A7 is the newer reference, I only want to see this one on my extraction of attributes.
What property of the block reference will tell me that it would be purged if I used the purge command?
As I want to detect what's the old block and which one is the current block reference.
The problem is I only want to extract the attributes from the newer block reference.
The old block reference is coming up... how can I filter that out of my loop results?
I know I could just purge the drawing and my problem would be done with.But I need to do this in a manner that only accesses the drawing from a read-only manner.
