Roblox's tools for solid modeling and physics include constraints, forces, and attachments.
| Constraints vs Align, Forces, and Attachments | |
| Constraints | Constraints like Rigid, Ball in Socket, Hinge, Prismatic, Cylindrical, Universal, Plane, Rope, Rod, Spring, Torsion Spring, Weld, and No Collision manage how parts interact and move. |
| Align | Align tools (Orientation and Position) ensure parts align correctly. |
| Forces | Forces like Vector Force, Line Force, Torque, Angular Velocity, and Linear Velocity control movement and rotation. |
| Attachments | Attachments link parts and apply constraints and forces, enabling complex and realistic behaviors in your game. |
