I present to you today my drive-through hall / barn / shed or whatever you want to call them always before
It is 6.5 m wide (It fit 2 trailer next to each other) and ~ 20 meters long and has 14,480 polys.
It can be opened / closed from the outside only!
They can be placed and the gates work with UPK (open and close). Costs are one-time € 5,000 to build and no additional costs.
