error....geometries with rotational periodicity must have the z axis as the rotational axis and be symmetric about the x axis

Hi gasem,

The error hints this rotating geometry must rotate about z axis. I guess the geometry should be placed to an appropriate position.

hi ymao
thanks for reply
how can i do it. i means how i place the geometry toapproprate position

[ymao]

Hi gasem,

Studio could help.
In dock of Geometry, you could find tab of Transform as follows:
Geometry>Transform

Over there the geometry (entire surface, selected vertices, selected triangles, selected boundary) could be re-positioned by Translating/Rotating etc.

thanks for your guide. i hope you help me future again thanks dear
