AutoCAD LT :: Dynamic Block With Alternating Objects
Nov 20, 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 singlely 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 untill I've gone double the distance (400) when it gives me both / and .

Why the drawing title in my dynamic block will not scale up or down. The rest of the objects scale properly but just this the drawing title text attribute will not follow suit.
I tried adding position point and link, etc....I run out options and don't know how to fix this.
I have two "drawing title" lines in my block when I use the, stretch, move, scale parameter the attributes lose the position (the drawing titles lines are stacked) and will not scale with the rest of the objects. I tried all tricks that I could possibly think of but no success.
maybe LT2012 has a bug that does not allow me do this correctly?
I have tried to make a dynamic block using annotative objects, text leaders, etc. The block was created initially as annotative but later somehow after going over it in the block editor. It has lost it's annotative properties. Is there a way to make a dynamic block that is not annotative, make it annotative. this block has only visibility features.
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?
After all this time is there a way to assign layers to different objects with a block? Perhaps using Visibility states or Lookups?
As an example:
I have a dynamic block with a door swing and text. As I increase the size of the door the text changes to reflect door size. The objects are all on the 0 Layer. When I insert the block I can assign a 'Text A' Layer to the text and a 'Door A' layer to the door. So when I switch layer states around I will either see the door, the text or both. Then I move to the second floor which has been stacked on the first floor. I insert my DB and assign layers 'Text B' and 'Door B' respectively to the text and door.
Finally when I go to my layer states I either select 'First Floor' or 'Second Floor' and the respective blocks appear depending on the layer state.
I believe there is a way to create a block of displayed objects that are shown within viewport. I know I have done this before with basic Autocad. The closest thing at the moment that I can think of is "SOLPROF" but that only works for 3D objects.
The way I remember the command working was you started off with the command, select the objects with the viewport/or maybe it was just the viewport, the command made an instantaneous block of the objects that were only within the display area.
It's possible to create a dynamic block programatically? I want to create a command that captures different selection sets of drawing objects and assign them to different Visibility States of a new block deffinition, on run time.
how to control the draw order of objects created within an array in a dynamic block?
I have a wipeout, which works fine on the array source, but when the array produces babies, it places them infront of everything (which is only logical), making the wipeout useless.
Can I set array babies to have the same draw order as their parent?
1. What is the easiest way to find points that are not constrained? I get a notice that the block is not fully constrained and its a nightmare going through all the lines trying to find where I need to apply a constarinet.( I can't wait to get off ACAD and back to Inventor.)
2. When I try to save a dynamic block using the Save Block icon under Open/Save, if the dynamic block is not fully constrained, and I click save, when I reopen the block to edit all of my constraints are gone, this has happened twice. Now I just exit by Xing out and saving changes.
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...
I'm trying to make a dynamic block of a column radiator.
It should be very simple. It's a 46mm wide module that comes in a range of heights (300, 500, 600, & 750mm) and a range of assembly widths (9, 13, 18, 22 & 27 modules wide - more commonly given as mm widths of 414, 598, 828, 1012 & 1242 respectively).
My attempt at constructing it has gone quite well, but when 'stretching' the block a ghost of the core 414 (w) x 300 (h) unit remains. I attach the block to give you a better idea of what I mean.
I have a drawing ("SURUBURI.dwg") with several dynamic blocks ("M12", "M16", "M18" ... an so on...). I want to insert in my current drawing, one of the blocks from SURUBURI.dwg, for instance the block named "M12".
For that i tried creating a new command "INSERT_M12" that has the following script :
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 dynamic block with several actions and parameters. There are three grip points. Two are visible. One appears when you move one of the other grips. If i insert or paste this block near my template, the X/Y basepoint stays near the template when i drag the block on the template with one of the other two grips.. When i print the drawing the basepoint stays visible and the scale on my printed drawing is not correct (smaller).
I am creating a dynamic block of a conveyor belt it has a set number of widths and needs to be stretchable in length, which I have managed to do. The motor is placed half way down the length of the conveyor and needs to stay centered
I know I need to use the move command and put in a factor of 0.5 somewhere, but I can't remember how to do it.
Is it possible to mirror a rotation within a dynamic block?
See the attached drawing. I am trying to have two rotations within a dynamic block, but only one grip. When the grip is rotated one half of the block rotates while the other half rotates in reverse. The resulting action would be much like the wings of a butterfly.
I have tried many different combinations of parameters, actions and constraints with no luck. The block in the attached file was as close as I could get. Have I reached the end of what AutoCAD is capable of?
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.
Last week I opened the drawing and added some visibilty states etc. to the block.
Now when I open the block or insert it into another drawing for whatever reason the cursor or crosshairs stop at the edge of the block. And if you move towards the middle of the block where there isn't any lines etc. the cursor will move to that point until you hit another line then it will stop moving again.
I've been reading some other posts for different dynamic block topics/issues and read that everyone has problems when you get to higher numbers of visibility states, but when I edited last week I only added 7 states. Is that enough to make this happen? It sounds like everyone else that is having problems has far fewer visibility states than on the attached drawing.
