Missing "object" during the render

[thonyqqta]

Hi,

I'm using Sketchup 2015 and when I'm trying to render I see that the Result is my scene without an object, to be specific, the missing object is an antenna (in every angle), but when I render the image with "Visualizer" I got the antenna and all the objects in the scene. Please take a look at the 2 images attached.


Any help is more than welcome,
Best regards,
