Applying/setting up Miter corners for non-continuous/complex Linetype Polylines with Global Width

[Jooogyerek]

I want to create Miter corners for complex Linetype polylines and sadly I can only create Rounded corners right now with FILLET.
Is there any way to create Miter corners? Command, variable… anything?
Thanks

Check the radius setting for the FILLET command. It needs to be zero if you want a sharp corner.

 

If that doesn't help, please provide more information.

All corners are 0 radius corners.
By the way the sharp/Miter corners reappear if I change the polylines to Continuous linetype. But it doesn’t work if I use more complex lines.
Does it works with your setup with complex linetypes?
