AutoCAD Dynamic Blocks :: Linear Parameter Stretch With Polar
May 6, 2013
I am trying to be able to have my outreach arm stretch horizontally and on angles of 5 / 10 / 15 degrees from the pole. I have been able to make the polar stretch for this and it works fine though what i am trying to do is have the luminaire height also stretch and move when the size of the outreach changes (i can make the linear dimension work the way i want though not the luminaire parameter) as when you add the paremter into the stretch action is only moves the top and leaves the bottom at the same location which is not giving me the correct height.
The block itself is alot more complicated then this I have stripped most of the parameters out to make it less confusing but the end result would allow the user to input the outreach angle, outreach length and luminaire height. I have attached drawing for your reference.

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.

The linear stretch works fine but changing the length affects the position of the tick marks of the polar stretch. If I change the degrees to 0-360 then it's not a problem but I want to restrict to 285-345 deg.
I can't figure out how to move the base angle of the polar stretch with the linear stretch.

I have a linear stretch D1:
Distance Type: Increment
Dist Increment: 1
Dist Minimum: 1
Dist Maximum: unlimited
I also have a linear stretch D2:
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.

Polar Stretch and Linear Stretch work properly independently, but when their "grip points" are overlayed and I'm trying to stretch the right side and stretch and rotate the bottom side of the drawing - Polar Stretch is screwing up.
The idea is to NOT to use them separately, but with one stroke having "grip points" overlayed all the time.

I am very new to dynamic blocks. I am starting off learning the small stuff before I get to the larger more complex blocks to convert to dynamic.
I have a reference block I am trying to "master" all the functions we would like to see.
I have two major concerns.
1) Why can't I rotate this block (via rotate action) and have the attributes stay at angle zero? I thought I built the parameters and actions correct.
2) I haven't ran across anything that explains how to stretch 2 linear parameters at the same time with the same distance (ex: stretch both at .25, .5, .75)

If there was a way to have multiple stretch boxes when selecting one linear parameter.
I am currently working on 2D isometric drawings. I have lined up my views horizontally, so one stretch block is sufficient for stretching things vertically (I just drag the box over all my views), but I cannot find a way to efficiently stretch several views horizontally.
I was hoping that a solution to this will allow me to either select one grip and move at most 4 views horizontally, or just enter ONE value in the quick properties window.
The only idea I can think of now is to just make 4 linear dimensions, 4 grips, and have 4 quick properties inputs .

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.

I am trying to have a dynamic block that will show the profile of a steel plate, detailing the angle of a bevel. Including the plate thickness, the land, gap and the actual angle of the bevel. I've gotten most of it figured out, but having a grip to SET the angle at a specific number, while maintaining the drawing's integrity is proving difficult. I have attached the block I have created so far (minus the previous attempts to rotate the beveled angle).
BVL_detail.dwg
The base point of the rotate parameter should be at the junction of the bevel & land. I need it to stay connected to the end point of the top-most flat line as it rotates, which means the lines need to stretch to match the changing angle. It will either rotate that line along with it, or if I apply a stretch tool, it gets all disconnected and just plain wrong.
One of the things I am liking about my current set up is I can grab a grip, and then type the number I need and it will pop on into place. Was hoping for the same effect if I typed in the angle, it would be exactly that, while also adjusting the drawing.

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.

I need to use the dimension created by an action-parameter as a variable in a user defined function but AutoCAD will not allow me (see attached).
How may I access the action-parameter's dimension ?

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.

I've made this block . when i rotate the vertical line I need to add lines every 15° as you see in the image, i've seen that polar array is not possible in the dynamic blocks.

I have a block of a circle and a line coming from the left and right side quadrant of the circle to a common point (see pic). I want to create a dynamic block using a Stretch and Rotate parameter. You select the block, the Rotate point (grip) shows at the end of the two lines. I can grab that grip and rotate both lines and circle by moving this point around the screen, but cannot Stretch this point to a new location at the same time. How can I have the Rotation end point follow the Stretch parameter?

How do I manipulate a height parameter all of the dynamic blocks in the drawing from one single field? Say a field located in the drawing properties or on the drawing itself.
For example: Multiple blocks of different walls of same height with other blocks of things on located on those walls, dependant on the wall height, all linked to and changed by a single field. Possibly a Wall Height field located in the custom tab of the drawing properties.
I can pickout each of the blocks and change them at the same time in properites menu because they all share the same parameter name. I would just like to have that height parameter of every block in the drawing, that has that specific parameter controled by a single field. Which I could enter a new height at anytime that would change every block in the drawing to that height.

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 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 ?

See attached DWG. Two offset arrows.
This works as long as it is not rotated, but distorts if rotated and then stretched.
I'm using ACAD2006.

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.

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 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.

See the dwg attached.
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!
