AutoCAD Dynamic Blocks :: Comms Rack (stretch And Fields Update)
Apr 21, 2013
Attached drawing file. What I am after is the ability to be able to stretch the length and/or width and update the two feilds depending on the new distance. At the moment each time I specify the distance parameter as the object it works then when you close and test the block it just shows #### as if that object no longer exsits.
The second problem is i am trying to be able to stretch the comms rack width and to update the door to the rack (the dashed part of the block) to the same length as the width of the rack. Ie atm the rack and door is 600mm and 600mm if the width was updated to 800mm the door will also scale to the same. I attached example in white just below the block.
I have a couple of attributes suing fields within a block. But they don't update on opening. I need to do a manual field update to get them updated to the latest values.Tried various combinations of "fieldeval", but this was no good.
We have a new title block which now contains various fields to automatically populate the drawing number, number of sheets, issue etc. The problem we have is when we go to zoom all or extents on a layout tab it moves the layout to the right each time. If we only have one layout or we use a plain title block i.e. with no fields, the zoom works fine (layout stays put in the center). This is also true if we directly insert a field onto the layout - again no problems.
The cause of the problem only happens when a block containing a field is inserted onto the paper space of a layout and,there are multiple layouts containing blocks with fields.
I am trying to update blocks for a client. Each block has a line of text with the block name in it. I would like to automate these with a field so that if the block name changes or a new block is created from that one, then the field would update as well. I am running AutoCAD LT 2012 currently.
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.
Is there a way to have the grip stay in the correct position when the distance multiplier is .5? It seems to "get ahead" of the original location.
In the attached block, when I stretch the block with the grip, the grip ends up off the end point. Both actions have a .5 multiplier, with the left side having a rotation of 180 - so both sides stretch equally in opposite directions.
Also, there are 3 views with parameters (width/depth). Is there a way to get the user to enter in the sizes without having to select the size on each view? Basically a table that has a 'user input' field so the size selected changes everything at one time.
Is there a way that i can put a Field in a block that does not have a locked down specific item to look for? What i'm trying to do is have a block that contains a field linked to an object (Polyline) and read its length. My problem is that when you put a field in a block you have to define what it is looking for so if i select "Object" in the field its asking for that object while i'm in the block editor, is there any way to have it pause for user input so that i can select the object after the block has been inserted?
I created a dynamic block to represent a room in a floor plan. It displays the dimensions and area of the room and can be stretched. But it's defeating the whole point of being dynamic. The area won't update unless I do a regen.
I've seen comments blaming MTEXT for the problem, so I tried putting the area field in a line of TEXT or DTEXT. It still didn't update unless I did a regen.

I've created a dynamic block with listed increments e.g. 36, 42, 48 inches width. The dynamic window block that comes with autocad has the same incremental stretch.
This block shows the tick marks as well as a the value in a dynamic input box. How can I have the value displayed in my custom dynamic block. All I have is the "tick" marks.
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 .
If you have a drawing open and the Tool Palette Architectural open click on the door. It has "tick marks" where you can stretch the doors opening to (24", 32"). I want to know how to add those "tick marks" to my blocks .
Attached is a block that I am using for Finish plans. Basically how it works is that it is suppose to be inserted and then stretched to indicate a finish change in the floor. When I insert it and stretch it, it works exactly as I want it, but when the scale is changed, the center tag resets to the original center before the block is stretched. I would like it to stay in the center relative to the line that is stretched.
Not sure if you understand, but if you are good with dynamic blocks. You will notice that the dot is annotative where as the line that stretchs is not. I cant have the line change because it will be stretched between two areas with different floor finishes and that will stay consistant. I want the block to adjust so that it is the same size on all the scales of the drawing.
I'm working in AutoCAD 2010 and I would like to make the process of creating 2D documentation easier and faster for myself and my collegues, but during the process I've hit a dead end.
I would like to use fiedds (or something simillar) to partly automate the creation of 2D documentation. We have sheets organized in a specific way and I would like to create a custom field for each of the categories (eg. drawing number, number of parts, designer...) that could be edited easily like the parameters or object properties can. Basically what I would like to do is create custom fields or some other object that can be edited from a list in AutoCAD and then automatically refreshed in text boxes. Is there a possibility to do something like that using fields or perhaps a different solution?
I have drawn a simple block that I want to stretch in two directions manually or from the properties palatte.
My block works fine once and then breaks down. Stretch the block in the 'Y' direction. Deselect the block. Stretch the block again and only the grip moves. Edit the block and close the block, the block resets.
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 created a dynamic block with a polar stretch. I insert the block, then have to select the grip to rotate/stretch it. Can it be inserted and then rotated/stretched all in one action? The insertion point is at one of the line and the polar stretch grip is at the other end.
Distance Type: Increment Dist Increment: 1 Dist Minimum: 1 Dist Maximum: is it possible to set the maximum distance to equal D1-2.5??
Both linear stretch D1 and D2 can be stretched independently. So D1 may be stretched to 100, and D2 may be stretched to 50, but what I am trying to do is ensure that D2 will never stretch beyond the distance of D1.
I was wondering if it is possible to use dynamic blocks to stretch a rectangle evenly, using only 1 point? I have attached a PDF of a rectangle with 2 lines coming out of each side (before & after picture). I want to use dynamic blocks to pick a point at the top right of the block, so that when I pull it out, the lines will extend, but stay attached to the rectangle. I also what the rectangle to stay in the center at all times.
I'd like to modify a dynamic door block I've created so that I can stretch by door leaf size OR structural opening size, but I'm not sure how to do this.
Incidentally, I think the block has some flaws:
- I think the 'center/flip point' is not exactly in the center! - The frame size should be 40mm, not 32mm - The packing zone should be 30mm, not 6.38mm!
I foolishly thought i'd sorted making hatch work within a dynamic block that requires user input to set length and width of block...the hatch would fill to the revised size when the user sets the length and width in the properties dialogue...woohoo. Off I go home from work having defeated the nemesis of the day.
Open up my drawing today and can I get the hatch to act as it did yesterday?
I built my block (a simple rectangle all told) added my parameters in block editor. length and width linear actions with 0 grips as I don't want stretching by grips. Added the stretch actions. Tested the block (without hatch)...working. Only then did I hatch, so into block editor and using associative, send to back, normal island detection and selecting the rectangle to hatch. tested block ...working. great. Inserted the block into new drawing...working.
Opened AutoCAD today...Not working...hatch remaining as original size
Tried building new block exactly as I did yesterday...no joy...
On a side note...it works if I leave grips on but only if I use the grips to activate the hatch (it still doesn't work by just typing into properties though) that's not going to cut it as I don't want to be telling everyone to wiggle the grips so to speak.
I am working on a dynamic bi-fold door block. I have added actions that adjust the two leaves of the door to correspond to different opening widths and allow the jamb width to be adjusted. I am now trying to add flip actions in both directions. There is a regular swing door block in the drawing and I want the bi-fold door to have basically the same functionality as the swing door does.
I can't seem to get the angled stretch actions required for adjusting the opening width to work after flipping. I have tried including the stretch actions in the selection set for the flip but it does not seem to work.
I try create simple block where I change dimensions of polylines. Everything work with stretch partameter until I try use search parameter for change dimension.
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'.
I cleaned up my block and I am trying to use a field to reference a polyline for it's overall distance. The distance changes with my lookup action. After rotating and going back and forth from "On" - "Off" - "Both Off", then back to "On", the red polyline doesn't stretch back on it's original plane.
I would like to find a way to give a maximum and minimum length to a stretch (or move) but without absolute values.
simplified example of my block:
I have 2 squares, of which one big on, and a smaller one within the bigger one. I want to be able to stretch both squared indefinatly (no problem there), but the big square may never become smaller than the small one, and the small one may never become bigger than the big one...
In other words: the inside square should always stay inside the bigger one, no matter the size of the squares.
The problem with this block is that I have a hatch pattern between the squares, and as soon as i stretch the small square outside (or equal) to the big square... the hatch pattern 'crashes'.
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.
I am trying to put a polar stretch on the block uploaded, but it doesn't seems to work (maybe because of my constraint? ). If something major is wrong with it, is there another way I can make the same drawing proportional when i rotate it and stretch it ? Also, after that I have to use it for vlisp.
