A note for other newbies. This is my second ever 3D printing project. When I loaded it in the Snapmaker3D application, the software said that the project went outside the build area due to the extra length added from the raft base. The project was loaded from side to side in the build area. So I moved the project to be diagonal , problem solved. 
I am currently printing the first fence as a fast print and it looks great.
Update 1: after printing, when I tried to separate fence from raft, it split. Now reprinting with Normal Quality to see how that goes… we live and learn.
Update 2: as soon as the fence finished printing i removed it from the raft… all good. Am now printing other sides
Update 3: All finished, fro newbies like me be careful when snapping of the gate support, I actually broke the fence to the side of the gate.
