What you need to do:
Step 1: Log into the shared project server using Roblox Studio on your computer.
Step 2: Use the Model tab to insert basic 3D shapes (called "Parts," like blocks, cylinders, or wedges).
Step 3: Use the Scale and Move tools to build the structural walls for your country’s room or a historical monument from scratch.
Step 4: Use the Color and Material menus to style your build beautifully—remember, do not use any pre-made items from the community Toolbox!
