On warcraft 3, you can make a "NEW" model (Model as in Unit or Doodad) and the model can be shown in the portait in the bottom also it shows death, doesn't crash but sc does
This isn't WarCraft 3. And considering World Edit is brand new compared to StarEdit, Blizzard obviously changed a lot to fix certain issues it had with StarEdit and make new features. WarCraft 3's editor is so much better than StarEdit, but this site is for StarEdit so no one cares about WarCraft 3.

Wrong. you can just click attack and then click on valid terrain and the units you ordered to attack will attack all units encountered on its "trip"
But if its cloaked and you can't click on it then that means you can't see it withouut a detector. Thus, you can't attack it.
