In Russian, direct objects of transitive verbs (like показывать) usually go in the accusative case without a preposition.
• путь (path/route) is masculine animate? No, it’s inanimate. So its nominative путь becomes accusative путь (unchanged).
• There’s no preposition because the verb itself (“to show”) directly takes the object “the route.”
The preposition до means “up to,” “as far as,” or “until.” It requires the genitive case.
• офис (office) in genitive singular becomes офиса.
So до офиса literally means “up to the office,” i.e. “to the office.”
