Attaching Model

[perk]

I have been trying to attach my model to a list of questions I have but everytime I attach it this text field goes blank and the model disapears. Am I doing something wrong?

Perk,

Most probably your file size is too big for an attachment (afair it's 512 kb now).
You can upload bigger file to our Kelly's server, see information here:

or actually, if the file is not a "secret" one, even to the 3D WareHouse (you can upload 10 mb files there).
