AutoCad 2D :: Not Displaying Length With Stretch Action In Dynamic Block
Aug 25, 2011
I use dynamic blocks a lot of the time and most of them have a stretch action in them. What used to happen would be that whenever I clicked on the block I wanted to adjust and then clicked on the stretch action, it would show the distance from the base point and I was able to type in the new length of the object I was stretching. But now whenever I click on the stretch action, it shows that the current length is 0 and it is asking for the distance from the current point, not the base point. How can I change it so that it is always just the distance from the base point?

is there a way to associate a stretch action with the length of an attribute value (i.e. # of characters in the string) or is this something left to vlisp?

In my Project I build a static Block by inserting dynamic blocks from a template dwg and then explode them.
Actually I create a new Data Base, insert the blocks from my template, set the according Dynamic Properties, Explode the Block in the temp DB and then wblockclone the resulting Objects in my destination BlockTableRecord.
This works fine, but:
in my source dyn. block there is an associative surface defined by a Polyline(Rectangle) , attached a stretch action to change the size. I can set the Width parameter, after the Explode the polyline itself is updated, but the planar surface is not... so if I explode this block I get a well stretched Polyline and the "base" surface.
Manipulating the dynamic Block works fine... If I have stretched 3D-Meshes, they are ok as well. It seems to be something with the planar surface object.
Dim objs As New DBObjectCollection idsToImport.Clear() If Helpers.Registry.GetValueFromRegistry("ExplodeSubs").ToString = "1" Then ' debug switch bref.Explode(objs) 'the dyn BlockRef in the external (temp) Database bref.Erase(True) For Each [code].......

Sure wish you could manipulate the Column Offset of an Array Action with a Stretch Action.

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.

How do I stretch a hatch in dynamic block? It does not seem to work if I select the hatch along with other lines of a counter block.

I would like to stretch my extruded shelf using a list of value settings.
I completed the steps in block edit but it will only allow my object to move to my value sets.
In 2D I have no issue.
What am I missing when modifying 3D objects.
See attached blocks.

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 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.

my problem is whenever i make a new block a stretch point appears even if its not a dynamic block . also its not a stretch point, because when i click on it, it just move the block , and it always appear on the coordinates 0,0 it cause me a problem when I insert the block , autocad use this point as a base point , and its very far from the real block .

I am trying to insert a dynamic block and position and stretch the block, using the linear parameters, depending on values entered into a form.
I managed to create a form that would draw a series of boxes. And i managed to create a routine that would insert a block and size it depending on fixed values but i can't link the 2 together.

I have a block which is a simple rectangle with a height and width attributes that when I edit, change or update the height and width attributes I want the rectangles height and width to change as well.
I know I can go backwards using fields and the attributes would show the stretched length and width but is it possible to go the other way?

why the width parameter is only moving one side of the column. I drew both stretch actions following the same steps, then changed the multipliers to .5 and -.5 and only one of them moves. I've redone the block twice so what is going on here?

I have a block which I want 2 visibility states. VS1 and VS2 share some objects and not others. I have a linear parameter in each which I want to do a stretch action on. The stretch action in each visibility state acts upon entities both shared and unshared between VS1 and VS2. This doesn't seem to work..

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'm working on a drawing and I want an action to work on two diffrent dynamic blocks.
In my case, I wish to have two blocks that I can rotate by one rotation grip.
How do I manage to work this out?

I have a problem with dynamic blocks.
I have inserted a dynamic block (with .NET) and changed the value of a dynamic parameter (Linear). The block is stretched as it should be. (no problems here).
After a fiew other routines, I select the block again (by using its objectID) and a want to get the coördinates of the grip of the linear dynamic paramter. Is there a way to get the coördinates based on the linear dynamic parameter and its grip points? code in vb.Net?

I know that stretch will not affect major or minor radius of an ellipse in dynamic block.
What I would like to be able to do is use properties of an ellipse and some kind of parameter to be able to affect values in properties.
I know how to get ellipse radii data out of a block, but I simply cannot find a way to get them back in...
Is there a way to link field data back to block...?

In the attached dwg, I have a dynamic block "Platform" which is used several times. I have an adjustable length, with the array set to repeat the toggles (end view of 2x4) every 2', not including the last 6". That works perfectly, except one thing. "Distance1" is the distance of the parameter, because this was the only way that I found to stop the array from showing up within 6" of the last toggle. When I insert "Platform," and click the arrow to stretch it, I can type in the distance desired minus 6", and I'll get the correct length of platform. However, I'd like to be able to type in the actual length, and have the array work appropriately (the same way it does now).
Then, I'd like to create a custom toolbar that has a button to click which will insert this platform and ask me what the length of the platform should be (the entire distance). After specifying an insertion point, the block will insert at the correct length, with the appropriate toggles.
Here's what I'd like to do with it: using datalink, I'd like to count the following: how many copies of each length of platform is in the drawing, with toggle count and length of platform specified. I have already figured out the datalink to get the value of "Distance1", it's only the issue with the toggle count that I'm trying to figure out.

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.

I have a dynamic block for HSS column. Previously it was always 1"x1" and I would just scale it to the proper column size I needed. Ignoring the wall thickness.
But if there was an asymmetrical HSS (i.e. 4x6) the wall thicknesses and radii of corners would look funny.
So now I want one that has Stretch Actions to change the size of the column. I added a Stretch to one side, then the other with distance multiplier of -1. But as you can see on the attached, the Linear Parameter baseline doesn't stretch. I want to have the Parameter Distance the actual full width of the column so I can change the columns with the Properties Palette. Otherwise, I would just start the Parameter from the center of the column.

i'm trying to do a polar stretch and array for rigid insulation. RIGID2.dwg is my best option. but as you can see in the jpg, the first line should have arrayed already, because the gap is over 2". i tried to follow the instruction someone used for the clothes hangers URL.... and it resulted in RIGID.dwg, with the lines rotating off the main line.

The classic example of this, is a plan view of a door which shows you the opening, the arc and the door. How can I put a stretch on the opening and the door with a link in between, so when you stretch one, the other stretches with the same value?

I am in the process of fixing one of our dynamic blocks. It's a fairly simple fix where there was a typo in one of the names of our items in the lookup that needed to be fixed.
I changed the name of the item in the lookup table. I went and did the test block and it seemed to work fine, but when I bring the block into a drawing, it reverts back to the old lookup as if I did nothing at all.
I made sure that the path was correct and I even just dragged and dropped straight from Windows Explorer to no avail.Does AutoCAD keep referring to the old block? Did I forget to change something else?

We have specialized electrical schematic drawings on what is termed roll-drawings. These roll-drawings are simply 12" tall and variable width type drawings. We've had some as short as 24 inches and as long as 900 inches. As a result we use these section dimensions to distinguish circuit boundaries. It's not a real dimension, just a way to distinguish what circuit is located where. I've tried to recreate it using a block for improved automation as currently we just use a lisp routine that draws an arrow and lines. It looks like the screen capture of my block below. Is it possible to have the inside endpoints of the lines automatically stretch outwardly toward the arrows as the attribute Value changs?

I have created a dynamic block with stretch points. I used the tester in the block editor and all works fine, but when I insert the block into a drawing, the grips for the stretch action are in a completely different place...I don't mean a different place on the block, but a different place in the drawing...way out there. so if I go into the block editor for the block while I'm in the drawing...the parameters have now moved way out of the way also, in the block...but if I actually open up the block itself and then go into the block editor, all the parameters are where i placed them in the first place.

I need this block to do the following:
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.
