Drape command

I am using the “drape” command. typically it creates a grid of lines throughout the drape but now when I use it, it is only creating the drape but the lines going throughout are not showing up. I want these so I can edit the polys.
can anybody explain this?

Are you in a working display mode that is not displaying isocurves?

Hello - Drape makes a surface, not a mesh. If you want to edit the control points, you can turn them on with F10 ‘PointsOn’. Does that help at all?
