Problem with gumball and sphere


Hi all,

We’ve encountered this morning several instances of the gumball not working for spheres giving: Unable to transform 1 object.

Attached is a file with a sphere. I’m not sure how this situation is created. Any thoughts on how to solve this?

Check, sorry, missed the error message that the file was too big. Fixed it.

Hi Arend- the sphere is a bad object… how was it made? Was it scaled up from a smaller sphere?




What kind of things can be scaled up with no bugs? I’m learning some these clean processes, clean files things. Such as retracing curves into a pretty clean closed curve after making the mangled up hybred freaks. Also the problem with triangles on trimmed surface edges, etc that come from commands that never had real trim command in them. Only the rhino processing that somehow involves a trim. That problem and dupborders as I go will definitely help. ANyways, I was just wondering about say scaling up curves, and how scaling up curves that would be hard to create again clean might fare as far as bugs/bad objects? I suppose someone could scale up their curves, then go trace with only NEAR osnap on, and get a fairly exact clean version.


hi pascal, the sphere was created with the sphere command from the menu (Solid > Sphere > (First one from the menu, not sure about the name at this point), no crazy stuff happened as far as I know. I’ve encountered this only with spheres several times today during workshops with 2nd year architecture students. Perhaps it was scaled a bit, (factor 10 max?)

That is odd- if you can turn on CheckNewObjects for a while, while working as you have been, you will be warned when this kind of thing turns up- it would be good to know what causes it- I see that the sphere is located quite far from the origin, that may have something to do with it.
