Breaklines not working?

[chris.83300]

I have a drawing with 3D poly line breaklines - standard
and 2D poly - proximity.

The 2D poly types do not appear to be applying correctly, i.e. surface's trainagles cross them all over the place like they are ignored..
I even tried the 'convert proximity into standard option on and off'

Have you tried Projecting them to the surface you want them to affect? Or in your settings, do you have an Ignore elevation set higher than the vertex elevations of these PLines?

Well, the 2D poly's are on Z=0, and yes, min elevation is set to 200.
But I set the min = 200 so not 'bad' points come in, however, it seems in this case the 2D poly is left off?

Do they show up in the Item Viewer? Are they Splined or fit curved plines? There are a total of 4 KB articles containing breaklines on the ADESK site.
