Using Fit or spline on polyline with broken linetype

[CaptainCollision]

When drawing a polyline with a broken linetype, AutoCad always starts and ends each segment on a section of line rather than a gap and adjusts the length of the end dashes if necessary.
When I edit polyline and try to fit curve or spline, the linetype is corrupted even more, often creating quite long sections of unbroken line with just a few breaks.
Is there any way to prevent AutoCad from altering the character of the linetype in this way?

Try
PEDIT [pick the line] "L" and "OFF"

I think the Captain wants "ON" for the Ltgen so the linetype generation is uniform through the polyline.

On it is, Guys. Many thanks

 

[CaptainCollision]

Now. Does anyone know how to set the linetype generation to come ON as the default?

Set PLINEGEN to 1 to make the default "ON"

Wow. You woulda thought AutoDesk would have made that one the default. Probably dreaming aren't I?
