When Show Surface Isocurv is turned off, everything is off

For instance, if I revolve a shape in wireframe with isocurves off, then the gumball is not centered, zoom is not centered, and boundingbox gives the wrong result. Once the display mode is switched to Shaded or if I show isocurves, the problems are resolved.

Yes, this appears to be a classic - someone also reported this with spheres with the isocurves turned off…

Hi Peter - thanks, yeah if there is a render mesh the bounding box is taken from that, otherwise, the wires… . I’ll see if we can get this fixed.
