Create Sphere Bad Object

I have a user who found what seems to be a bug, where creating a sphere in space creates a bad object. I updated to the latest SR to see if the problem replicates and it does. The problem:

If I create a sphere at the origin (file is in millimeters) with a radius of 50,000 - then a normal sphere is created. It is a good object.

But if I create a sphere in space, then the object that is created looks fine, however it is a bad object because it cannot be edited or transformed. When running the SelBadObjects command, it selects the sphere created in space. This is true on the user’s machine, as well as my own computer, so this seems to be an issue across Rhino. This “bug” persists on SR 7.14 as well as the latest SR 7.17

Just to recap the steps:

  1. draw a sphere at origin = good object created
  2. draw a sphere at point indicated in the file (radius = 50,000) = sphere is created as bad object
  3. SelBadObjects - will select the sphere created at the point in space. Sphere cannot be edited or transformed

I am attaching files for convenience, thank you!

Hello- I see that, thanks.

RH-68538 Sphere makes a bad object
ToNURBS on that will make it no longer bad, but of course that should not be needed…

Ha, yes ideally would not be bad but that is a useful workaround for now! Thanks for the quick reply.
