Convert curve to arcs no preview

hi all,
We used to be able to see the preview of the convert command on any number of curves, now it seems to be limited to 41 curves total, doesn’t matter the # of control points. Not sure if this is a graphics card issue or what. If someone could please confirm this on their Rhino it would be greatly appreciated. I’m on
Version 5 SR6 64-bit
(5.6.31028.18305, 10/28/2013)

I’ve been getting along fine mostly without the preview but its getting bad now when I really need to see how closely the conversion is matching my original nurbs.

thanks.

So far, I can’t reproduce that. I do have to Zoom in pretty close as I fiddle with settings like tolerance and angle to make more and less, but the preview keeps showing.

I suppose it could be OpenGL feedback issues with your graphics card drivers or settings.
In Options - View - OpenGL, I only have the first option checked and I’m running relatively current (4 montis old) drivers.

Hey John, I’m gonna assume its a card issue. I can’t reproduce it on different machine with the same SR version. thanks.
