Display Isocurves

I’m afraid I’ve done something foolish, but I don’t know what. I can’t seem to get the Isocurves to display in any mode (shaded, wireframe etc)

I’ve checked and unchecked the isocurve display box in the display menu.

I’ve reset to the default setting in the Options - View - Display modes

I have selected and de-selected the ‘show isocurves’ box under the ‘general’ tab in options

I’m out of ideas. Can anyone help?

I’m using Rhino 5 64-bit

Thank you,


Never mind, I found it. Under the properties tab.
