AutoCAD Dynamic Blocks :: Rotate Line With Parameter Constraints?

May 29, 2012

I've only got LT2008 at the moment, but this is a pet project that if my office upgrades me I want to finish.

Is it possible to rotate a line by using the length of a separate line? But the degrees of rotation need to be worked out by the length of the line

as in the following sum

angle of rotated line = (fixed number/360) * length of linear line

AutoCAD Dynamic Blocks :: Rotate Array Parameter Individually?

Aug 25, 2011

I am trying to create a block that has a stretch and array command, but I would also like to rotate each arrayed item indvidually. However I cannot select the rotate parameter as part of the array function, so the block end up only containing one rotate grip.

AutoCAD Dynamic Blocks :: Stretching Same Parameter In All Blocks In Drawing From One Field?

Jul 15, 2011

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.

AutoCAD Dynamic Blocks :: With Attribute Text - Set Constraints?

Aug 27, 2013

I am trying to set constraints to this block and having some issues. I want to constrain the attribute text so when I stretch the block from the grips the text centers itself automatically within itself. The constraints will not let me pick the grip on the attribute text as a point.

AutoCad 2D :: Rotate Parameter And Action To A Dynamic Block

Sep 17, 2013

I am attaching a rotate parameter and action to a dynamic block.

I get the "Specify base point" bit okay but I can't figure out what "Specify radius of parameter" does.

Do I have to include or exclude other parameters like Flip or Stretch? I get some weird results when I rotate an object with other parameters.

Is it possible to place the Grip in a specific place? It always seems to like to sit on top of another parameter name.

AutoCad :: Create Dynamic Block Using Stretch And Rotate Parameter

Apr 26, 2013

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?

AutoCAD Dynamic Blocks :: Circular Hollow Sections - Thickness Constraints

Aug 22, 2013

I am trying to make a Dynamic block for Circular Hollow Sections. So i have a block properties table with 3 columns.

SIze (description)   |   Outer Diameter  |   Thickness

i can add a diameter constraint to the OD no problem but how can i add a thickness constraint? i cant pick say a linear or horiz between the quadrants of each circle it does not let you.

Now clearly i could convert all my tabular data to Inner Diameter instead of Thickness but i was looking to see if there is a way i can do it like described?

Also - i think i could also do this with an equation in Parameters Manager but for some reason that does not open, every time i click it the dialog does not display nor does it show anything at command line, i know this means its maybe corrupt but i can afford the time to reinstall just now.

AutoCAD Dynamic Blocks :: Rotation Parameter

Aug 24, 2011

I've got a block that has a couple of rotation parameters. The main one works OK. But the secondary one that is incremental and only 180 doesn't. Everything looks OK but the objects don't rotate according to the parameter but 90 degrees from what I think it should.

AutoCAD Dynamic Blocks :: Getting Parameter Value From Attribute

Nov 10, 2011

I need a rectangle block which on insertion prompts me for some data (name/tag/item number) and then displays it (this I can do). This is al pretty straightforward. But I also want to be able to fill in width and height and then have the block stretch to the correct size. So basically what I think I need is to have the value of a parameter refer to the value of an attribute. I've gotten it to work the other way around, where the attribute displays the size of one side of the rectangle (after stretching and regenerating), but I'd really like to have it working the other way.

AutoCAD Dynamic Blocks :: Attribute In Visibility Parameter

Dec 17, 2012

What I'm trying to do is have a graphic scale with a set list of scales the user can pick from. This was easy using the Visibility Parameter.

However, I want to add a "custom" vis state where, once they select this option, the attributed definition box will pop up and give them the option to input whatever scale they are using.Check out the attached .dwg to see what I've done so far (I just have the attributes on the "custom" vis state).

AutoCAD Dynamic Blocks :: Link Parameter Value To A Function

Aug 14, 2011

Is it possible to link a parameter value  to a function? I want text or attributes to never be "upside down".

If it is rotated with a rotation parameter the text would need to be automatically flipped or rotated if the angle is less than say >3*PI / 4 and  < 7*PI/8.

AutoCAD Dynamic Blocks :: Constraint Stability - Rotation Parameter

Jan 22, 2012

I have been trying unsuccessfully for several days to achieve a stable setup for the attached. This is the closest I have been able to get so far but as you can see if you change the width then the rotation parameter, the stability of the block very quickly breaks down.

The problem seems to be associated with the move action which determines the center point of the angle parameter. It seems to only work properly when you change the width parameter and the rotate handle is in the 180deg. Any other position of the angle parameter results in incorrect alignment of the geometry.

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.

AutoCAD Dynamic Blocks :: Attribute Not Rotating And Stretch Parameter

Jul 21, 2011

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)

AutoCAD Dynamic Blocks :: Block Rotate At Insertion

Jul 30, 2011

I have a simple block, I would like to do the following:

Type: Insert

Specify: Block Name

Click spot with cursor to have the block placed

Rotate the block for orientation

I know that if I use the Tool Pallets I can specify rotate on insert, but do not always want to use the Pallete.  I also know I can assign a rotation parameter to the block so I can grip and rotate after insertion.  Is there an easier way?

AutoCAD Dynamic Blocks :: Setting Parameter Values At Block Insertion?

Jun 16, 2011

how (if) I can set up my dynamic blocks so that I can set the parameter values as I insert the block, rather than with the grips afterwards?

To take a simple example; I have a block consisting of a rectangle, with 2 linear stretch parameters - length, width. Can I set it up so that when I insert the block, it asks for the length and breadth,just as it would for attributes.

AutoCAD Dynamic Blocks :: Move Attributes In Constraint Parameter Environment

Mar 12, 2012

I have a dynamic block that I am trying to add some pretty basic functionality to (at least it seems like it should be simple!). Since I’m still relatively new to DB’s, I figured I’d give some background on what I’m trying to do, cause maybe it could be done with a much easier approach than I have come up with. So if you don’t feel like reading the details, see the fourth paragraph for my actual question.

The block is a sheet reference annotation (that shows:  SheetNum/TotalNumOfSheets)  that we typical put in the notes section of our construction drawings.  It looks nice when the text (which are attributes), lines up with the text in the note (usually Mtext, but sometimes a Mleader). So I constantly find myself completing the tedious task of placing the block at the insert point of the Mtext (which is always justified LEFT TOP), and then calculating the distance down to line that I want the block to line up with.

So what I want the block to be able to do is to be able to have the user grab the block by its basepoint, place it at the insert point of the Mtext object, and just enter the text height of the Mtext note, the line space factor, and the target line of the note that the sheet reference block should line up (the input would all be done via custom block properties in the Properties Palette).  And since we almost always use a text height of 0.125 and Line Space factor of 1, those will be the defaults, and really the only thing that would need to be entered would be the line number of the Mtext that the annontation should line up with.

I already figured out most of the constraint parameters necessary and calculated the offset equation using custom parameters. I have all the linework moving correctly using the vertical constraint parameters, however, I cannot figure out how to get the Attributes to move along with the linework. I know how to move text and attributes using Action Parameters, but I can’t do it with Constraint Parameters. So I figured that maybe I could chain an Action Parameter to the Constraint Parameter, but I couldn’t figure out how to do this either. Also, I am using visibity states and would like the visibility grip to move along with everything else as well.

My block is attached. I used some lines for the Constraint Parameters to be associated with, but they are only there for the block to operate correctly, therefore they are invisible in both of the visiblity states. Probably not the best way, but it works.

AutoCAD Dynamic Blocks :: Link Move Action To Visibility Parameter

Sep 12, 2012

I've got a block with 2 lines of text, the second line being optional.  If the second line is omitted, the first line should be moved down, so it's centered.

I can handle the second line being omitted with a visibility parameter.  And I can handle the first line being moved down with a move parameter.  But how can I link the two?

Ideally, I'd be able to re-use the line 1 attribute and display it in whichever place was correct, but that doesn't seem to be possible.

AutoCAD Dynamic Blocks :: Rotate Attribute 180 Degrees About Its Center?

Jul 11, 2011

Attached is a dynamic block for a civil grid tick.  It's my first time creating a dynamic block so it's probably not the most efficent use of the dynamic parameters etc.

I have it setup with 4 visibility states to allow the northing and easting attributes to "rotate" about the center of the grid tick, to give options for readablity and/or text overlap.

What I wanted to add was figure out how to make the individual attributes flip 180 degrees about a point (roughly the center of the attribute).  Again this would be for readability.

AutoCAD LT :: Auto Select Rotate Upon Placing Dynamic Blocks

Nov 13, 2012

At my last job, the CAD manager there had certain blocks which, upon insertion, automatically selected the rotate command. i.e., as soon as you click to place the block, it was free rotating.

I've search for the answer, but everything just tells me how to put the rotate command inside the dynamic block, but I don't know how to make it "auto-jump" to that immediately upon insertion.

AutoCAD Dynamic Blocks :: When Creating DBlock - What Does Angle Represent In Rotation Parameter

Jan 9, 2013

Just exactly what does "Angle" represent when placing a "Rotation Parameter" in a DBlock?

I've tried a bunch of diff angles and haven't noticed a difference.  I'm trying to figure out just what effect diff values would have.  I thought that maybe when rotating the block instance, I'd only be able rotate it "so far" (270 degrees in the example I've shown).  But it still went well beyond that.
