collada import question (simple question...)

I used the collada import to import an object into blender. the object seems fine in the editor, but when i hit “ctrl p” it vanishes (all i see is a grey screen).
if i add a cube next to it the cube displays fine, which meens the problem is not in the hardware but in some setting of the object.
the problem persists in textured/solid/shaded/wireframe so it isn’t that issue.

i’m pretty sure i’m missing something obvious here and that this isnt really a difficult question - any suggestions?

thanks in advance,
Sh

  1. Shortcut for starting ge is ‘P’ ,‘ctrl+p’ is used to parent objects.
  2. I cant really figure out what could cause your problem, since your saying problem persist in wireframe mode too so it cant be a normal problem. So better atta

You sure are. You didn’t attach your blend file to your post.

Attached is the file.colladaTest1.blend (550 KB)

Your scene is a dogs dinner. You have objects with vastly different scale values (some are 1 but huge and the rest have a scale of 0.003). Import your objects again with the same scale.

Thanks!

but how do i avoid that next time and “import my objects again with the same scale”? and how do i even find out what scale things are in?
(this object came from the google 3d warehouse, and i intend to import several other landmarks from there…)

If possible, I would still appreciate an explanation about the route of the problem - why does scale have this effect? and how do i fix it myself in the future?
thanks in advance,

I would really really appreciate more information about how to solve this as it has happening to me almost every time i try to import objects from collada/kmz…

thanks in advance,

you say you press P and everything disappears, well it was partly answered in post 2.

by pressing P, you have put yourself into GE mode

thanks, but that is exactly what i want to do - what i don’t understand is why these imported objects disapear, and if/how scale is linked to the matter(as was sugested above)
i need to be able to see these objects in the game, and really can’t understand why they are vanishing…

for example, here is another cleanly imported file. i did nothing but import, yet when entering game-engine moe it vanishes! why?!
