Classic Roblox cylinders were added in late 2007 ; one Roblox wiki page for Part/Cylinder is dated 2007-12-31 , which lines up with that era. A later Roblox video also references cylinder physics as “coming to ROBLOX in a few weeks” in August 2015 , so that was a much later update to how cylinders behaved, not their original addition.

Quick Scoop

  • Original addition: late 2007.
  • Physics/update overhaul: announced in August 2015, with cylinders being revamped soon after.
  • Why people get confused: “added” and “updated” are often mixed together in old Roblox history.

Context

The old shape menu already included Cylinder alongside Block, Ball, Wedge, and CornerWedge by the end of 2007. More than a decade later, players discussed that cylinders had “finally been updated,” which suggests the original shape existed long before the modern version of it.

Practical takeaway

If you mean when cylinders first existed in classic Roblox , the best answer is 2007. If you mean when cylinders got their newer physics/true- cylinder behavior , that points to 2015.

TL;DR: Cylinders were part of classic Roblox by late 2007 , but their later physics update happened in 2015.
