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.
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?
if it's possible to link a rotation with a stretching action. I have a text (or an attribute) inside a box that can be stretched. But if the box becomes too small to hold the text horizontally, I would like that the text automatically rotate vertically without any other action that stretching the box. If that is possible, is it also possible that instead of a text, there's an attribute, and that it rotates according to the attribute's length ?
I need to prepare a linked chain araound a defined path. (Please have a look at the attached drawing) My idea is to have one element of the chain defined as a dynamic block and to manually "rotate" one side of the chain element. After that inserting the next element (previously aligning the user coordinate system) and "rotating" the right part again to the next position...
After doing the rotation, the block definition will change and the next block will be "disformed". So far no big problem, but the grip of the rotation parameter will stay there and I am not able to "rotate" the right part back into the old position (0 degree).
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.
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'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.
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.
I am looking to create a dynamic block that changes in scale, ex. If I have two (2) viewports in paper space, one 1/4"=1'-0" the other 1/8"=1'-0" I want my blocks to appear to be the same size in paper space.
Also, I would like my blocks to change attributes/features ex. If I have a "light switch block" I would like to have the option of switching the block from a 3-way switch, 4-way switch etc.
