Sebby,
concerning the copied dimensions, this is indeed an easy reproducible bug.
I've opened an issue at github:
https://github.com/LibreCAD/LibreCAD/issues/998Thanks for reporting this.
For the dashed extension lines, there is no setting in LibreCAD. I don't know any standard which defines extension line as dashed lines and also no code in DXF definition I think. This would be the reason, that there is no option for it.
Your work flow is the only way for what you want, I have no other idea for this.
Is there a valuable reason for this non standard dimensions?
