Dynamic block - how would you create a serpentine block ?

[chris.virgo]

I have been trying to create a serpentine line dynamic block which includes an array where the lengths of the two parallel lines shown in the .dwg file can be altered (they would be the same length though) and the radius of the two semi circles also can be altered (again same diameter would be needed for each), then the entire arrangement arrayed to however many columns I require.

hi,

Please add Some Sketch or Sample.

Here is a starter

-created a nub on an arc

-turned it into a path array  >  nub to arc

-turned it into a block

-added a radius constraint

add a scaling operation inside the block to the arc and you should be able to have different path diameters (or something to that effect)

that's how it is sitting inside the rectangle

Best Regards

>>Here<< you can see a partial solution:

- you can array the base serpentine in any number

- you can change the width of the serpentine

- you can change the radius of the arcs

But - I did not yet find a solution how to assign the distance of the arrayed elements to the changed radius. Maybe this first idea helps you to find a final solution.

Hi Jurgen - Thank you for coming back to me with this one . I think with using AutoCAD LT I can't quite make the block do what I want it to do as setting constraints is only available in full AutoCAD. 

I think it likely there would be a way by setting constraints to the arrangement that it would result in the parallel lines moving with the radius arcs.

Thanks for your help with this though as the test block you created I think will still be helpful - my main requirements are for the line spacings to be either 200mm apart or 150mm apart so I have created two blocks from your test one with these two spacings. this then allows me to accomplish most of what I wanted to do with the block .

Thank you everyone for your assistance on this.
