make line adjustable in a block

[Jrooker06]

I am using Autocad 2015 and i want to try and bring in a block where i can edit a parameter that will adjust a line (or lines) without bursting the block. like how you can bring in a block and change text ( edit atribute) without bursting? does anyone know how to do this or if it is even possible? I have uploaded a dwg and a picture to show what i am working on and what i am trying to achive.

BEDIT the block after inserting it.  Be aware that will modify all instances of the block in the drawing.

Something like this?

Yes, that is more of what i was looking for. how did you create this so i can do it to other object?

It's a Dynamic Block.  The line inside the block has a Stretch Parameter, with a Stretch Action attached to either end.  I would suggest consulting AutoCAD HELP files, and or Youtube to learn more about Dynamic Blocks.

There's also a sub-forum just for Dynamic Blocks where you might find some use info and help  http://forums.autodesk.com/t5/dynamic-blocks/bd-p/154
