Lisp Available to Stretch Dynamic Blocks Like A Spline?

[Jim Clayton]

Does anyone know of a Lisp, that can take a Dynamic Block, and give it stretching properties, whereby it acts like a spline?  The stretching would be able to curve any/every direction, like a piece of wire.  Would greatly appreciate any help.  Tks.

Basically if I had a dynamic block, and curve drawn, I'm trying to stretch it parallel to the curve.  Picture that.  Tks.

hi, no respond maybe can try other forum has dynamic block expert?

Just curious still a bit vague how a wire stretched?

stretching by end? like rubber band? 

 or like different x-scale y-scale?

Are you looking to do something like sweeping a shape along a spline?

There is this :

But I don't think I understand OP's question too... Maybe some example DWG with before-after case or picture could reveal his idea...

Apologies for the delay.  After much searching I believe what I'm actually after is something to the effect of Stretching a Dynamic Block, or setting a Dynamic Block Array Path along a Spline...similar to the attached video.  This is going to be used to draw Flex Armor/Spiral Armor, which closely resembles a/c ductwork.  I have a block for it already, but sometimes the path that I need to draw it along gets a little squid-like.  This would save me a ton of time.  Thanks for the help.

Quite a few tools here for creating flexible ducts.

Thanks.  I believe I have this one already, and it's close to what I'm after but not quite.  I think I might be more in the market for a "Select Centerline, Insert Block, Insert Repeatedly-along centerline" sort of thing.  Anyone ever come across something like that?  Tks.

Think I might be able to get this to work using the ARRAYPATH command.  It's definitely not 100% there but it's pretty close.  Thanks to everyone for taking the time.
