appended meshes becomes invisible (>.<)?!?

I have a weird issue with my model, when I append a new mesh to my main model the new appended mesh becomes invisible, I checked the normals and everything seems fine but for some reason it’s not displaying anything. I’m using Zbrush 3.2 on Mac and I never had this problem before.

does anyone know what is wrong with my mesh?

ok I just found out what to do to get it back visible again, well at least in Zbrush because if you export the lv1 as a OBJ for some reason the OBJ still won’t be Visible in other programs at least that’s what happen to me in Z3.2. anyway so if you do have the same problem than me, when you append a new tool, it becomes invisible, in order to correct that, select the invisible tool in your subtool tab, then go to Edit, you will see you can undo 1 step, so just do so and the visibility of your tool will come back.
