AutoCAD Dynamic Blocks :: Using The Dynamic Array Function

Nov 21, 2013

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).

AutoCAD Dynamic Blocks :: Dynamic Block Linear Array?

May 5, 2012

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.

AutoCAD Dynamic Blocks :: Dynamic Array Revisited

Nov 24, 2013

I have been trying to get my 2D parametric model to work and am having trouble with the array.

I attach the model.  When I alter the span in the properties palette, I want the array to follow.  I do not want the grip to show as I eventually want to program the dimensions externally.I do not mind using AutoLisp or .net if I need to control the model using code.

AutoCAD Dynamic Blocks :: Stretch Or Array (JPG)

Oct 30, 2013

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 .

AutoCAD Dynamic Blocks :: Modify Array On The Fly?

Apr 3, 2012

Is it possible to modoify an array on the fly?

I've been playing around with an incrementing block, and have figured that you can get an attribute block to report its position relative to its origin inside a block,and have it report that back. If you can do that and do formulas, you could then have that creating an incrementing number. If however you were to want to use such a block for counting stairs or alternatively counting car parking spaces, and want to get the spacing of the array just right, you seem to have no choice in the size of array other than when editing the block?

Attached is what I have simply created. No calculations, just reports the position in X, but shows the possibilities. Stretch the text out and you get more numbers.

Time consuming to create alternative is to have to define each number object individually and do a move action, based on something like an object being stretched (length of stretched object becomes part of a multiplication factor for a move action). See Numbers increasing block attached. More precise but takes a while to create, and is limited to the numbers shown.

AutoCAD Dynamic Blocks :: How To Array In One Direction

Dec 14, 2012

 I'm using a 2-2D recangles that are 5'x16" and 10'x16" and I am trying to figure out how to array this in one direction, to the left, but have the array on 5' increments. Also, within each rectangle I am needing text to show which size it is.

e.g. If I drag the array to the left more than 10' but less than 15' it will apply 15'.

AutoCAD Dynamic Blocks :: Array With Lookup Table?

Jun 3, 2013

I have been looking for about three days on how to do the array with-in the dynamic blocks, but have been very unsuccessful. What I am trying to do is make a TJI joist that you can have a look up table that is classified as 'offset' so that you can eventually strech the joists to standard spacing, and use the array to work. So that I dont have to have a ton /  zero visibiliy states.

AutoCAD Dynamic Blocks :: Array Action With Text

May 22, 2013

i work at a small structural firm and am about the most experienced cad user here, which isn't saying much.  I have never wrote any LISP's or anything, but have created many dynamic blocks and have edited some programing my boss got from a previous employee for adding dropdown menus with blocks/layers/etc.  Just so you know my level of knowledge when it comes to answering my question. Also I am limited to using 2009 but other co-workers have up to 2013 so i would like this to work for all users. And i have done a bit of research but based on everyone elses level of knowledge am finding a lot of conflicting info and solutions that, to me, are in another language.

So I have a table that is created using polylines and text.  It's a funky shape and AutoCAD's tables are a pain for it. i have created a dynamic block where i can array the rows down and the columns left.  The issue is, i would like the test to come with each row, but still be editable once the block is done.  I have figured out if row one is composed of 5 columns of text put into a single attribute, it is fine. But once you use the array action, to say 3 rows (including now 3 sets of attributes) they are not editable.  So what is the work around, if there is indeed a work around?  

the two option i see are to only array the rows and columns and left the text outside that block and manually copy it done to how ever many rows the user needs....  Or to have 2 blocks come in together, one as described before, and the other which just arrays the text and then i explode it to edit each line.. but then if you later choose to addd another line you would be left with doing that manually anyway..

AutoCAD Dynamic Blocks :: Array Count Within A Block?

Feb 28, 2012

I'm attempting to use Excel to take data from a drawing and give me purchase and cut lists. 

I have successfully pulled the overall measurement from my dwg, and inserted it into a workbook. What I'd like to do now is to have a count of how many times the array function went into effect. For example, attached is a file containing a block called platform. When stretched, it inserts toggles every 2'. When I export the information from my dwg, I'd like for the program to not only extract the length, but how many toggles were inserted for each platform.

AutoCad :: Adding Array Count To Dynamic Blocks?

Nov 6, 2007

i made a simple little chair block , that can be dynamically pulled into theatre seating.

I am trying to get the "Count of Objects" revealed as mtext or an attribute in the block.

It seems that doing area mathematics on the total array size divided by the individual column/row sizes will give me the correct count.

Any recommendations on the "Field" that will work with this?

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

AutoCAD Dynamic Blocks :: Array Command And Getting Total Arrayed Value?

Mar 16, 2012

Started to play with dynamic blocks now got my head around stretch and tables but I'm looking to use the array command

this is what I want to try to achive

I have a dynamic block which has a array command in it so by simply pulling on the arrow the block will array horizontally giving me multiple items side by side

what I want to do is count the array example if I insert the block and and array to say 12 items side by side then I want to get the value 12 placed into a block attribute which is part of the dynamic block

I can then pull this data out of the drawing into spreadsheet so I can then create a purchase list of items

My immediate thought was to divide the the total length by the width of the item to get me a count but I don't know yet how to get this to work in the dynamic block

AutoCAD Dynamic Blocks :: Create Array Of Tread / Riser

Sep 25, 2009

I've been trying to create a stair block that will automatically adjust the riser height to to suit the total vertical rise of the flight, but am having issues.

I drew two 'tread/riser' Plines, and constrained the daylights out of them. By stretching the grip for the 'Total Rise' constraint, the risers adjust nicely, while the treads remain at their desired 11" depth.

My problem is that when I try to create an array of the tread/riser, (using a linear parameter aligned with the slope of the stair) I can't get the 'column' width to change as the risers change height. Instead the value remains constant, and the arrayed copies don't connect with each other.

Any way either to fix this so that that the copies connect 'head-to-tail'?

AutoCAD Dynamic Blocks :: How To Center Array Picket On Top Rail

Nov 29, 2012

I have created an elevation of a railing with stretch and array actions, however I have not been able to figure out how to center the array'd picket on the top rail.  I've added a move action to the main picket in order to manually center after the railing has been stretched between the two posts...however I'd love to have this automatically centered.

(I originally thought I could have the main picket stretch at 0.5 (so it would be centered), then array in two directions, however there is no angle option on an array paramater).

AutoCAD Dynamic Blocks :: Rotate Array Parameter Individually?

AutoCAD Dynamic Blocks :: Stretch / Move / Array Block

Jul 31, 2012

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.

AutoCAD Dynamic Blocks :: Array Multiple Objects Sequentially

Sep 28, 2012

It seems like this should be easy but it's not. I have a block with multiple components. I want them to array sequentially as I drag the grip. First one component, then the next, then the next. What I get is all 3 at once when I drag the grip far enough. I tried 3 separate linear parameters with their grips stacked but that didnt work either. What I have attached is a very simplified version of what I want, but I think once I get the concept it will be easy to elaborate on.

AutoCAD Dynamic Blocks :: Setup Array With Alternating Objects

Nov 21, 2013

I'm currently creating blocks for our office library. One of these is a grille with some apposed blade dampers on it. I'm trying to set up an array that will duplicate the apposed blades as I change the length of the grille. However, it will only copy the blades in pairs, not singly one after the other. Ie, the blades are 100mm apart, and in a / pattern meaning that each instance of / or 'should' duplicate every 200mm. Except when I lengthen the block by 200mm it won't duplicate until I've gone double the distance (400) when it gives me both / and .

AutoCAD Dynamic Blocks :: Adding Different Part / Block After Array

Nov 27, 2013

I have a block that when I extend it, a new 10' section is added. It will only add the 10' piece (array). What I am looking to do is find a way so that once I hit a total distance have it switch the part that it adds. So I have like a rail, I keep adding these 10' pieces and then once it hits 40' I want it to add the end piece which is different.

AutoCAD Dynamic Blocks :: Creating Array Within Block That Is Setup With Constraint Parameters

Feb 6, 2013

I'm trying to create a window block with a grille.  I've created the block and the horizontal grilles.  What I'm having a hard time with is creating the vertical grilles.  I would like to set up an array that would take the glass width, divide by 12, round up the value to get the number of vertical sections.  Here's the code that I've figured out:



GW=Glass width

How do I set up an array with this formula?

AutoCAD Dynamic Blocks :: Link Parameter Value To A Function

Aug 14, 2011

Is it possible to link a parameter value  to a function? I want text or attributes to never be "upside down".

If it is rotated with a rotation parameter the text would need to be automatically flipped or rotated if the angle is less than say >3*PI / 4 and  < 7*PI/8.

AutoCAD Dynamic Blocks :: Annotative Parameters Inside Dynamic Blocks

May 5, 2010

I've made annotative blocks and I've made dynamic blocks... My intent is to integrate both but I can't find a way to move dynamic block parameters separately at different annotative scales.

In other words, if I insert an annotative dimension and add multiple scales I can move the dimension grips independently at each scale. If I insert a dynamic block I want to be able to use the dynamic block's action "grips" to do the same. However, with a dynamic block, if I move a stretch action at one annotation scale it moves the action at all annotation scales.

The attached file shows a simple example.

AutoCAD Dynamic Blocks :: Adding One Action To Dynamic Blocks

Mar 15, 2012

I have created a dynamic block with several visiblility states. The block works great for what I need it for. however, I am trying to add one more action to the block but am having issues.

This block is essentially a 24" retail cabinet with the visibility states showing the different drawer and shelf configurations. I want to be able to lengthen the cabinet in 24" increments and have the visibility show for each 24" section.....e.g.  I want a 10' cabinet so I bring in the 24" starter block. Then stretch the cabinet to the 10' mark, then I can chose any drawer/shelve config for each 24" section (they are all different).

I can get the block to stretch in 24" problem.....i just want the visibility state to be duplicated as well for each section. Now as it stretches, there is only one Vis state and it only populates the first cabinet.

I could do this by copying the block over and over 5 times.....but I am hoping there is a way to make this dynamic.

AutoCAD Dynamic Blocks :: Link Dynamic Block Custom Rotation Action

Mar 22, 2013

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.

AutoCAD Dynamic Blocks :: Create A Dynamic Block For Glass Panel In Balustrade

Feb 28, 2012

I need to create a dynamic block for a "Glass Panel" in a balustrade. I need to be able to insert it, in one corner and stretch it in another corner, to suit the staircase angle.

I've created the block, but it isn't working correctly. I've attached a drawing, with the left hand drawing a sketch of how it needs to be. The right  hand drawing is my dynamic block attempt. As can be seen, when the block is stretched between the 2 points, it doesn't follow the angle of the staircase correctly (Very slight run off)

AutoCAD Dynamic Blocks :: Insertion Point Of Attribute Changing Within Dynamic Block

Nov 21, 2011

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".
