Piping isometric scale break on long length

[Virgule]

Hello,

 

Autocad newbie here. I've been researching this topic and finding nothing, prompting me to join a forum for additional input.

 

I'm drawing a piping isometric with long lengths of pipe I'm trying to shorten for a better page fit and legibility. I've drawn them full length and am now trying to shorten/break/jog them. I've found the DIMJOGLINE command to insert the correct symbol on the dimension line, but it's not freezing the value when shortening. I also can't use that command to apply the same symbol on the pipe line itself.

 

I need some help.

 

Thanks

Do a Google Jogline autocad lisp should be able to find some code that makes the jogline and suits your needs.

Here's an old thread on break line. Drawing cylindrical break line ?

 

For the dimension, AFAIK, you need to "Convert dimension to text" by right-click in the dimension editor or "Override" the text in properties.

 

This LISP should set the current dimension to the override.

Thanks to both of you, I'll look into this. I have a lot to learn.
