AutoCAD Dynamic Blocks :: Stretch And Array - Visibility States
Aug 12, 2013
I'm trying to create a block for angled handicapped parking stalls.
I used an array chained to a stretch in order to increase the number of stalls. It worked but for some reason it does not work in all of my visibility states. In some visibility states the array and stretch do not stretch together. The block should end with a stall but some end with a line and no stalls above it.
I attached a drawing with the blocks. The block named "STALLS-60-HANDI" it works correctly except in visibility state 9' and in "STALLS-60-4space Handi" it only works in visibility state 10'.
rename to dwg . fire wall would let dwg posting

I have a block which I want 2 visibility states. VS1 and VS2 share some objects and not others. I have a linear parameter in each which I want to do a stretch action on. The stretch action in each visibility state acts upon entities both shared and unshared between VS1 and VS2. This doesn't seem to work..

usage of dynamic title blocks with visiblity states and defining page setup override templates which use same for quick plotting using sheet sets.
I have attached a simple dynamic block that I built which is the outter frame of our company title block, it is designed to allow users to quickly switch between Landscape and Portrait orientations.
The problem I am having is when I go to define page setups for my Sheet Set Page Setup Override Template I am unable to use the "Extents" option with auto-center because the "Extents", as defined by the page setup, includes ALL objects in the paper space regardless of visibility, so my title block ends up being centered in a stupid way if that printing configuration is used.
The only solution I have found is to use the "Layout" option when defining page setups, but this option produces other issues in other ways when printing. I don't want to use the "Window" option either for the potential for users to be using the page setup overrides to print drawings using different paper sizes or drawings that were not originally created using the current template the override is designed to accomodate.
Is there perhaps a system variable that defines whether invisible objects are included in the "Extents" setting in the page setup? I'm sure you'll all agree that Extents is the way to go in this situation, but it is not performing exactly as required.

I have been working on a dynamic block that need to look like the attached jpg. Basically it needs to be able to stretch up to 50'-0" but in ten foot segments (part size limits) +/- an additional but in 1 foot increments.
I've got two blocks that will either array or stretch. But have not been able to get it to match the actual requirements. I have attached my current block attempt. Also as you can see from the jpg, the support posts usually alternate as well and I haven't figured that out yet either .

So, while it wasn't common before, I am finding a need for multiple visibility states in blocks more and more these days, since AutoCAD can't do it I was wondering what work around and tricks people had come up with??

I use the RIBBONS when using ACAD, when creating Dynamic Blocks with Visibility States I am able to add, rename etc the states, but when I need to tell ACAD what to hide and what to show in each state I cant seem to locate the button within the ribbons to do so.
I find myself having to switch back to CLASSIC view to use them and then back to RIBBON.
See the 2 images.

This is my first dynamic block, and I am trying to make a pipe elbow that is selectable for pipe diameter, arc angle of elbow, AND radius of elbow. I got the diameter and the arc angle just fine, but I can't figure out how to do the radius of the elbow. I used a lookup table for the diameter constraints and I used my visibility state for the angle, seeing as I couldn't find a way to accomodate arc angles with a lookup table. What I'm stuck on is the radius bit.
I need to be able to select the radius or the elbow as either 1.5x, 2x, or 2.5x the diameter of the pipe. So for example, if I have a twenty inch pipe diameter, I need to be able to set the centerline radius of the elbow as either 40, 50, or 30 and then have the outside and inside radii fit proportionally. So in the case of a 20 in diameter, I would need one block with one variation that has radii of 30, 40, and 50, another variation with radii 20, 30 and 40, and yet another variation with radii 40, 50, and 60. I could easily make a reverse lookup table to do this for a single size pipe, but in order to do it for each pipe diameter I would need to be able to cross reference the other lookup table to pull the diameter value, and then have the radii respond to that value.
If this is even possible? And if it is not possible, how I could edit the arc angles with a lookup table instead of a visibility state? Because if I could do that I could use my visibility state to do the radii instead. My other options are to create a second and third dynamic block for each variation, or to add each individual radii variation to my lookup table. The latter of which I won't do because that is far too many options for a lookup table that already spans beyond the extents of my monitor. How I could accomplish all three of these tasks with a dynamic block.
Attached is the block as I have built it so far.

Is it possible to select visibilty states of a dynamic block in a drawing, for ex. to count how many of each visiblity are in a drawing?
Ex.:
I have a drawing of a big pile plan with al lot of various piles in there. I made one dynamic block of the pile in which i can select what kind of pile i want to have visible. Now i want to count how many of each pile is in the pile plan.
If all different piles would be different blocks i could easily count with 'Block Reference' in 'Quick Select', but i dont know how to do the same with a dynamic block (which has one block name only) and its different visibilities.

I am working on a few dynamic blocks with ducts.The plan is when you stretch the duct to far it will automatically place a coupling and the next peace of duct.
This wasn’t the problem but if I connect more than 2 ducts it goes extremely slow. (see attached file)
I think that if I am using larger steps between stretching (still testing this theory) it will go faster but this goes against my nature of being possible to exactly decide the length on my one.

Is it possible to link text to each other through visibility states without creating a block within the DB? I have 2 visibility states. Right Section, and Left Section. All notes and text stays the same, geometry is the only thing that mirrors between states.
The hope is that when I update the text on the "Right Section" state, that the same text on the "Left Section" state automatically updates with what I did on the "Right Section".
I solved this by creating multiple blocks within the DB. That works great, however there HAS to be an easier way to do this.

I'm new to dynamic blocks. In my first attempt to create a simple dynamic block with various visibility states in which each would have it's own attribute, the only attribute that works is the attribute in the first visibility state listed. I have read all the postings I could find here in the group on this subject and have made the following changes suggested here to the block:
1. All attributes have distinct tags and prompts. (I even erased all the originial attributes and created new with original tags.)
2. All attributes are locked in position.
3. I REGEN after selecting a different visibility state.
None of these changes has had any effect. Still, then only attribute that opens an attribute edit dialogue box is the "W" attribute in the first visibility state listed.

I need this block to do the following:
1. Move the right piece so it ends at 3', 4', & 5'.
2. the move right hook and 'backing' to stretch/copy (or array) so it adds a hook to the right and fills in the backing.
so this means that a 3' gets 4 hooks, 4' gets 5 hooks and 5' gets 6 hooks.
3. the block as shown is the smallest configuration with 3 hooks.
I could just set up a visibility and draw each one at it's appropriate length but I'm trying to keep this simple block to a min size. If all else fails, that's the route I'll take.
I've tried a couple different configurations and I keep getting duplicates or the end piece doesn't move the correct distance.

I have a ventilation attenuator I would like to compile into a dynamic block.
At the moment I have the files in folder (Folder name is length) I wish to create a dynamic block per length.
Is there and easy way to compile this without having to copy and paste from the other files?

we have moved from AutoCAD MEP 2012 to AutoCAD 2014 recently using Dynamic blocks with multiple visibility states.
in 2012 we could select a dynamic block with a specific visibility state and select similar, it would only select the visibility state that was previously selected.
in 2014 that is no longer an option WTH?
i have tried a couple of system variables to no avail (pickadd, selectionmode)2014
selectionmode is not a valid SV in 2012

I have been working with attributes and visibility states for months, i've created a dozen blocks that have worked exactly as designed... Now every block i make with the same method is not working properly
attached is a really simple block. to the left are the 4 individual attributes in the block. on the right is the dynamic block with 4 visibility settings to show 1 attribute, 2 attributes, etc... everything is perfect in the block editor, in model space; vis state 1 shows 3 att's, vis state 2 shows 3 att's, and vis states 3&4 work as designed.
I'm under the gun to create standard blocks to collaborate with 2 other another firms.

In the attached dwg, I have a dynamic block "Platform" which is used several times. I have an adjustable length, with the array set to repeat the toggles (end view of 2x4) every 2', not including the last 6". That works perfectly, except one thing. "Distance1" is the distance of the parameter, because this was the only way that I found to stop the array from showing up within 6" of the last toggle. When I insert "Platform," and click the arrow to stretch it, I can type in the distance desired minus 6", and I'll get the correct length of platform. However, I'd like to be able to type in the actual length, and have the array work appropriately (the same way it does now).
Then, I'd like to create a custom toolbar that has a button to click which will insert this platform and ask me what the length of the platform should be (the entire distance). After specifying an insertion point, the block will insert at the correct length, with the appropriate toggles.
Here's what I'd like to do with it: using datalink, I'd like to count the following: how many copies of each length of platform is in the drawing, with toggle count and length of platform specified. I have already figured out the datalink to get the value of "Distance1", it's only the issue with the toggle count that I'm trying to figure out.

I have a dynamic block with visibility states.When I use the method BlockReference.Explode(entities) I get in 'entities' all entities including all those who are part of the visibility states not selected. But I want only the entities in the selected visibility state.What surprises me more, is that entities from other states of visibility, although they were added to the current space, do not appear.
How to retrieve only entities associated with the selected visibility state?Or how can I identify entities that are not part of the state of visibility?
var entities = new DBObjectCollection();selectedBr.UpgradeOpen();selectedBr.Explode(entities);foreach (Entity entity in entities){ currentSpace. AppendEntity(entity); tr.AddNewlyCreatedDBObject(entity, true);}selectedBr.Erase();

I'm trying to create a dynamic block with several different visibility states and for each visibility state I have created an attribute. Each attribute has a different text style because I need the size of the text to change when I change the visibility state. But on the model space I can only see and edit te attribute in one of the visibility states. How to create a block that allows me to see different attributes in different visibility states or that alows me to change the text stryle of the attribute acording to the visibility state?

In the past I have not managed to get attributes to constantly behave themselves if I applied a visibility state to them. Following posts by steven-g where he has a method to get them working together I thought I would give it another try. His method was used to link the attributes to a further reference attribute to reveal a field but mine is far simpler, just requiring one of two numbers to appear depending on the project state.
I had two attributes which toggled their visibility but only the primary attribute would display UNTIL AFTER I locked and prest the attributes, wherein it all looks to be working as wanted.
So my question is, why does it now work (and will it continue to do so)?
I don't know if I could get away with only one of those actions but since I had something working I didn't want to break it. I will test it once these drawings have cleared my desk.

I have made up an extensive dynamic block library over the year, however in the latest version when I have tried to modify blocks with visibility states you can not cycle through the different states it will just revert back to the first one.

i'm trying to do a polar stretch and array for rigid insulation. RIGID2.dwg is my best option. but as you can see in the jpg, the first line should have arrayed already, because the gap is over 2". i tried to follow the instruction someone used for the clothes hangers URL.... and it resulted in RIGID.dwg, with the lines rotating off the main line.

I want to be able to update a dynamic block with data from our SQL Server database using a VB.NET program.
The dynamic block is configured to show office locations and has the associated office addresses for each office location embedded within the block. However, over time, offices close, new offices are added, addresses change, and so on. Plus, we have a dynamic block in each sheet size for several template types. So, updating them remotely would be a huge advantage. I'd like to just click a button, and know that the offices in the blocks were up to date and accurate.
Currently, I can use VLISP and the DBX technology to open each file and change the addresses. But, I cannot figure out how to change the visibility state (office name) in the prompt list. Anyhow, I want to drive the changes from a VB external application rather than having to open AutoCAD and run a LISP routine. So...
how to modify the following properties of a dynamic block using VB.NET?
1. The visibility states prompt list. (add, delete, modify)
2. The associated values. (add, delete, modify)

I run Autocad 2010LT at work, where I do fire alarm drawings. I've been trying to create a dynamic block (sort of a one stop-shop) for my wiring diagrams, and wanted to include device text with it.
My question is, is there a way I can create a dynamic block with multiple visibility states where each state has it's own independent/editable attribute definition?
Basically what I'm trying to acheive is the ability to make a different description layout for each one of my device types. (They all have a different function, and a different address style) Really so I can minimize the time I spend editing the formats when I'm trying to crank out a plan review ASAP.

I am trying to insert a Dynamic Block and change it's Visibility State. I can insert the block, and the visibility state changes, however, if I manually try to change it after, it does not change, even though the value has changed. My code executes and returns no errors, so I am assuming that I have done something wrong, or missed something out.
public class MyCommands { [CommandMethod("MyGroup", "Bolts", "MyCommandLocal", CommandFlags.Modal)] public void MyCommand() // This method can have any name {
[Code].....
If I insert my block manually, I can change the states and it works fine, but the code seems to break the block.

I 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 have successfully created a dynamic block. I can insert it into AutoCAD, and it behaves like I want, except for one thing.
I can select the block and change it by taking a grippoint and place it at another position. So my block is e.q. stretched, just like I wanted.
But then. When I want to use the ordinary STRETCH command of AutoCAD, I can only stretch the insertion point of the block, but not the grippoints. Is there a way to set a grippoint to be select edable by commands like STRETCH.

I have a block of a roof screen. What i want to do is to stretch it & have the slats on the front & also the supports on the rear array @ different intervals. The slats on the front would array every 6-1/2" (The slats are 5-1/2" wide with a 1" gap). The supports array every 4'-0". I have tried to do this multiple ways with mixed results. How to get my desired outcome. I am enclosing my block.

Is there a way to have the grip stay in the correct position when the distance multiplier is .5? It seems to "get ahead" of the original location.
In the attached block, when I stretch the block with the grip, the grip ends up off the end point. Both actions have a .5 multiplier, with the left side having a rotation of 180 - so both sides stretch equally in opposite directions.
Also, there are 3 views with parameters (width/depth). Is there a way to get the user to enter in the sizes without having to select the size on each view? Basically a table that has a 'user input' field so the size selected changes everything at one time.

I have created a small dynamic block that manipulated some lines (attached). The properties table allows s1, b1, b2 and c to be modified. The white lines control the cyan and red.
The red-lines have an array within (green lines) which I want to lock to the blue line parametrically. The array may be dragged physically but thats not the point; its need to be automatic (Revit style).
