AutoCAD Dynamic Blocks :: Stretching And Dividing
Jul 26, 2013
Is there a way to make a dynamic block where I will insert the total length of this “ panel”. Say 3720mm, and that it will divide the “panel” into equal segments with a maximum segment width of 1240mm. ( so with 3720mm that would make 3x 1240mm segments)
Say it would be a “panel” of 5500mm it would be 5 segments of 1100mm, and a “panel” of lets say 3750mm would make 4 segments of 937,5mm.
I made a drawing to illustrate what I mean, A dynamic block for this will save a lot of time!
(here is the example)

I have noticed in some dynamic blocks that have wipeouts in them, that they dor not stretch with dynamic actions.
In fact, they don't seem to be capable of stretching.
I have read some post about "Autodesk Sketchbook Designer for Autocad 2012" causing some conflicts.
Is there an advantage to having it installed?Do I need to uninstall it? or not?
Does it interfere with anything else in Dynamic Blocks or the drawing file?

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.

is there a way to make dynamic blocks stretchable similar to a mleader,
the blocks i create are only stretchable by grips, and not by crossing
(i am using linear or point parameter stretches)

I have a 4' light fixture that is a rectangle. Right now I have it set up to where I can stretch it and it copies it’s self whatever length that I stretch it in increments of 4'.
Is there a way for me to modify this so that when I stretch it along an arc, that it copies its self and rotates its self along the edge of the arc?

I can create a block where you stretch a line and the opposite side stretches equally in an opposite direction but I can't find anything with stretching equally in the same direction.
The block in questions is a door with windows to the side. The door size will remain fixed but as I stretch the window jamb I would like the two mullions to stretch to create an equal stretch.

I have been trying (albeit unsuccessfully) to draw a DB that requires a hole spacing of 16" maximum. The problem with this is that a pair of holes will need to be added or subtracted based on the width while not exceeding this 16" maximum dimension, but maintaining even spacing. I.E., when this block is stretched down, a pair of holes needs to be subtracted and the remaining holes need to be spaced evenly. I have attached the block drawn at it's maximum width and most required holes at this width with stretch parameters for each hole set. The best idea I could think of would be visibility states for each series of holes that would be activated when the block is stretched accordingly but just can't seem to make it work.

Please see the attached drawing. It's for a conveyor system, and the idea is that when you insert the block, you could then select the size of the conveyor and the angle of the turn (straight sections are another block).
What is suppose to happen is, when you insert the block, you stretch the conveyor to the size desired, and the rest of the block should scale to match. Then you select the angle of "turn", and you're good to go.
I got it all to work except... when you stretch the line out, everything scales, but the line doesn't stay in place and just stretch to the left, it moves, which leaves a gap where the conveyor should be.

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.

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'm looking at a block which has multiple visibility states, 2 of which show a beam as a side elevation, where the beam can be stretched to give a length. This works well.
But I'd like to be able to have the beam stretching so the bottom flange of the beam can stretch relative to the top to give an angle to the beam end, and also have the lines representing the flanges (whose position will vary depending on the steel size) can also be stretched to give a neat cutoff.
Stretching the bottom of the bottom flange is easy, but I can't figure out how to stretch the inner lines? They would have to be moved a proportion of the distance which will vary between beam sizes/flange thicknesses, so putting in a fixed multiplication factor won't work. The mathematics to set a multiplication factor based on other elements of the dynamic block is easy, but is it possible to have such implemented on a varying basis?

I have a box, and inside that box, there is another box. Connecting/joining both boxes are two lines on all four sides of both boxes. What I don't know is how to stretch the outer box (dynamically) from the top right corner, to any size i wish to drag it out to (keeping the inner box in the center at all times, and keeping the lines joining the boxes, connected to both boxes).
I can:
-Dynamically stretch the outer box from the top right corner, keeping the inner box in the center
I can't:
-Keep the lines joining the two boxes connected to the two boxes.
There is a picture attached that shows the box before it is stretched, and a picture of the end result that im looking for. I just need to know how to dynamically stretch the first image to generate the second image.

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.

I am trying to make a block that I can stretch. The end pieces (gusset block) never change size. The only piece that needs to stretch is bar that connects them. The gussets are always on a 45 degrees. If I stretch it over 5 inches on the X axis, it should move -5 on the Y axis.

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" sections....no 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.

I have a block I am making into a Dynamic Block. I will be adding in different visibility states. Depending on the visibility state the block would need to be inserted from a different point.
My question is, is it possible to add multiple insertion points to a dynamic block so depending on the visibility state it defaults to the correct insertion point?

I've made a simple dynamic block, a rectangle with a hatch and added a linear stretch to it. The stretch works fine on the rectangle itself, but the hatch only gets moved.
I've attached an image and a drawing containing the block.

I use autocad 2011 LT and I have some problem with polar stretching!I have to get from A(see picture) to B but C is always happening! I want to put in an angle in te propertieswindow so that I become B. the angle is variable but the middle stays the same length!

For my AutoCAD class we are supposed to make a dynamic block of a basic theater flat which we can then stretch into different sizes. I was able to do the vertical stretch no problem, but when it comes to the horizontal stretch, the lines do more of a move action then stretching. I have redone it several times but it still won't stretch properly.

I have a profile drawing of a pv module that is a dynamic block. The dynamic block has options to let you select different attachment points. The location of the attachment points and where they attach to the pv module (the rectangle) is a manufacture requirement to maintain the warranty.
I am trying to modify this dynamic block so that I can stretch both the length and the height of the module. The height was the easy part and is working in the attached dwg.
As the length changes the location of the attachment points need to change as well but proportionally to the length. Basically scaling the rectangle but only on one axis.
I have seen references to how when you insert the block you can change the scale factor or once the block has been inserted into the drawing you can set the scale for one axis in the properties menu but is there anyway to do this dynamically?
The pv modules (the rectangle) come in a variety of specific sizes so scaling the block upon insert wouldn't really work anyway.

I want to make a simple dynamic block showing a plan section of a window with one mullion between the window jambs. I've succeded making the block stretchable to any given length that is required.
The problem is, that I can't figure out how to keep the mullion right in the middle between the jambs.
Is there any simple way to get there using the actions and parameters in the block authoring palettes?

I'm trying to create a dynamic block for plywood. I have the stretch parameter working so that I can stretch the plywood to the needed length. I also have set a rotation parameter based on the various roof pitches that we use. The problem is I would like to be able to rotate the sheathing to a 45 degree angle and then stretch along the 45 degree angle. Once I rotate the sheathing the stretch does not follow the rotation angle. I have attached the file.

Is there anyway to link standard AutoCAD Grips and there commands to Dynamic Block Actions? I want to stretch an arc by its midpoint grip. This accomplishes something that no other commands do.

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 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 )

new to dynamic blocks but looking to streamline my wiring diagrams here and have created a block that shows the typical wire styles we use in a simple easy way. I now want to add an overall flip to the entire block and have not been able to find set this. I would prefer to use the same label and go from there. I have included the block to show what I mean. It is only working on the single visible item at the one time. I know this has to be possible just let me know what I am doing wrong. I am running AutoCad LT 2013

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)

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 need to do some repetitive task on a lot of dynamic blocks, unfortunately, when I open each file, AutoCAD keeps asking if I want to open it with the block editor.
Is there a way to disable that dialog and open the files as normal dwgs?
A hint: BLOCKEDITLOCK doesn't make it, it shows another dialog...
