Hello all,

First post here at the forums!

I'm a young gun at a Structural Engineering firm and i've got a question that has baffled me for the past few days.

I've been tasked with turning this symbol: ~ (the squiggly), which we use for instances which a normal breakline is too big, (and also for piping) into a dynamic block. The reason for this is because resizing it is a pain in the butt when we need to use it in circumstances where the default size isn't enough. 

I've tried watching youtube tutorials and have pounded my head against the book for the better part of the day, and have been stumped at how to give it stretch points, but still retaining it's base shape. Every time I do this, the grips only distort it. 

I'm sorry if this is confusing. But can anyone lend me a hand?
