As title said, I want some units other than SCV, Probe and Drone, to be able to build structures, e.g. a Terran Bunker.

I modified the buttonset but unit still cannot build once I click building button and place into terrain, because unit just go to the build point then do nothing.

Is there anyway to make it achieved? Thanks a lot!

See this post. You've modified the buttonset but not the requirements. The unit will not be able to create the buildings because it does not meet the requirements to do so.

Thanks, tested in EUD Editor v3, a little different but works perfectly

Also, do you mind to take a look at my another question here:
