Contours not Displaying on layout/viewport

[pilarcajv]

Hi Guys, need your help.

the surface contours is not displaying on my paper space, how can I display it?

I checked the surface styles and layers I've used.

Hello,

When in paper space double click in the viewport and open layers manager.  Carefully examine all layers to ensure that your surface-related layers are not off or frozen or frozen via viewport layer overide.  This assumes you checked your drawing ambient layer settings to verify which layer surface objects are placed on.  You may have that layer frozen by layout overide, but all your surface style layers are on.

Same thing here!

If I create a new layout it does show contours but then again a couple of days later stopped showing.
