Making building what can produce unit

[punisherw3]

I want to create some building that will be able to summon heroes in Starcraft II.
How is it done? I am not that good with the Galaxy editor.

Summoning a hero is the same as building any unit. Reviving a hero is an ability I believe (ability data base type). If you have problems with the requirememts restricting the hero number, try creating a trigger system to do it.
