AutoCAD Dynamic Blocks :: How To Keep An Object Centered On A Dynamic Block
May 29, 2013
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 am working on a dynamic block that I figured would be fairly simple. However, it is proving to be a huge annoyance. What I want for it to do is stretch the end of a polyline with a stretch action, while at the same time moving the grip of my block properties table. No matter what I do to it, the block properties grip won't move/stretch.
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.
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 am having trouble trying to add text to a dynamic block that will stay locked and centered when I stretch it left/right and up/down. The default text I am looking to have should be 36x24 (36 is the lenght of the unit, 24 is the depth). I can also upload my block.
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).
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.
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.
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.
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.
I have created d/blocks for my different pipe sizes i.e one block with a dropdown to select the different sizes and have done the same for my flanges. now how do I link / insert the flange d/block to the piping block so that I can export the information into a material list later on.
