Hi Pilou, sorry about that I think I understand correctly now!

Yes - that would definitely be better to clear any previous temporary result when using "Set dir".

I have set this up for the next v2 beta and actually all the changes required are inside the Extrude.js script command, so if you would like you can update your current version with the attached Extrude.js command script to get that change.

Just copy this one over top of the old version inside of the \commands subfolder.

Does that then do what you were asking about?

- Michael
