Changing Multiline style on existing mline

[Anonymous]

Hi,

Is there a way to change the  mline style of an existing line?  It is greyed out, but is there a system variable that could be changed to make this work?

Thanks

Russell

Unfortunately not, you can only edit the style.

Hello from France

Welcome to the Autodesk/AutoCAD Forums !

Not sure to well understand your question/topic !?

But if you want to change the style of ONE existing MLine, I have the correct VLisp routine ?

;; VLisp Routine :  Change_MLine
;; Change THE selected MLine to the CURRENT MLine style
;; and you can switch to Closed/Opened MLine ...

I hope it will help you ...

and for all mlines in the draw?, something like modify dim style or text style?, something update all mlines once time?

[jbrandenberge]

You can't even modify the style if there is an existing MLINE using that style in the drawing.  You have to delete all lines using that style or create a new style.  Would seriously be helpful to be able to just edit the style from the dropdown in the properties palette then have to delete or redraw all lines.

@jbrandenberge you can share your thoughts and program improvements for a tool they've ignored for 20+years here https://www.autodesk.com/company/contact-us/product-feedback

Or use a variant of AutoCAD that offers other tools for that same effect, or start using Dynamic Blocks for the same effect.
