block with dynamic control

[mazzetti68]

Good morning, everyone!
from a lot of work with dynamic blocks, but today I came across a function that I never knew there was and what it was for.. .that is dynamic control... in a few words look here:here the dwg:View attachment WELD After vis States.dwgthis also:http://forums.autodesk.com/autodesk/attachments/autodesk/154/16561/1/multiple%20visibility%20states.dwgI needed this because I didn't think it was possible to activate more visibility in the same block , but I just can't use them, and I really want to understand how they use it, which is from a couple of bears I look for on the net but I didn't find anything (except the example attached). ..someone who uses this feature knows maybe give me some tips to find tutorials (always that exist) or other material?
thanks in advance
hello and good day to all

It explains what you have to do. . .

in these days I have still documented a lot, but that I have understood and tried, with dynamic control I can only activate and disable a single visibility at a time, so in a few words what is not yet clear to me is if you can activate two visibility at once?Thank you in advance

I confirm that you can only insert a visibility parameter within a dynamic block.
Attached you find the block in the “Italian” version where I used only the circle and triangle, this for a matter of time.
open it and follow the next steps.
we analyze the block:
the circles and triangles that are part of the geometry of the block have been created, but also two circles in the upper part, which will always remain hidden, whose task is to create states 1, 2 and 3 that are nothing but the incremental steps of the linear parameters assigned to the latter to manage through the subsequent dynamic control parameter sx part of the visibility states. the move is assigned to have in function of numbers 1, 2 and 3 properties to be assigned to the actions of the subsequent dynamic controls.
a visibility parameter has been inserted to manage all the situations you want to achieve according to the elements you want to display.
then the dynamic control parameter sx where through the button add properties to the top right only inserts the left distance property and fills the table by hand with the data you see (from my block: dx key above the action icon – displays dynamic control table).
you do the same for dx dynamic control.
now we arrive at the crucial point i.e. to the dynamic bridge control parameter where two dynamic control actions were assigned at the same time to the parameter this to tie together the tables of the visibility states to the table with all possible combinations of view of the circles and triangles. we know that autocad does not allow to assign two dynamic control actions to the same dynamic control parameter. we see how to circumvent the obstacle.
we bring in the parameter panel dx button above the dynamic control icon > properties > click on the square to right of actions and add two times dynamic control confirms everything then immediately add the dynamic control parameter to the block, for convenience call it bridge and command line type the variable: bactionbarmode and impostala a 0 (zero) if everything is ok you should appear two lightning bolts where you click on it you can insert two separate tables (which will be tied between them) now you just have to enter the data (see my block).
if you have understood something you have been good, in fact the topic is quite complex and for the explanation I have confided that you are already an expert of dynamic blocks, however shortly I will realize a video on this topic and then I will certainly be much clearer.
Bye.

I needed this, because I thought it was impossible to activate more visibility in the same block.. .

Bah. Analyzing the block does not seem to me that through dynamic control mixes visibility states. his trick is in having created a disproportionate amount (40 to be precise!)

speaking of dynamic control, I used it time ago to create a block of a door in the plant that changing the angle managed the visibility of the opening (the arch that schematizes the race of the door)

gelyparis, thank you very much for the help!! I have now understood, even if I have to say that I have put a little, since it was quite complex the process of entering the data in the table... now with this function I will be able to get a lot
Thank you again!

You're wrong!
the assignment of two dynamic control actions to only one dynamic control parameter with the technique I described above allows you to have in fact two states of visibility one independent from the other thing otherwise impossible with a simple parameter of visibility.

I have a problem like that. I'm not too experienced with dynamic blocks and reading your advice I couldn't find a solution to my problem.
I have a block, which stretches it, I want it to generate an array of the central elements and that both oblique ends remain equal. the only thing I've managed to do is a block with two arrows, which change separately, so I have either an array or a stretch. Can I connect the two parameters somehow? or is there another solution to my problem?

I attach my file to understand the situation
