Model Tab

The Model tab contains tools for manipulating 3D objects in the workspace, creating detailed models, working with physical constraints, and adding advanced objects.

Model tab indicated in Studio toolbar

Transform Tools

The primary transform tools include Select, Move, Scale, Rotate, and Transform. When you choose a tool, visual draggers display on the selected object in the 3D viewport.

Mode

The Mode selector toggles between standard geometric transformations and simulation of mechanical constraints while moving or rotating parts.

Mode selector indicated in Model tab

Collisions

The Collisions checkbox toggles the collisions state when you're transforming objects. If collisions are off, you can move, scale, and rotate objects so that they overlap each other; if collisions are on, you cannot transform objects to overlap other objects.

Collisions checkbox indicated in Model tab

Transform Snapping

Snap increments for tool transforms are based on studs for moving/scaling or degrees for rotating. You can enable or disable snapping through the checkbox next to Rotate or Move, and adjust the rotation/transform increments via the input fields.

Transform snapping tools indicated in Model tab

Transform Coordinates

CtrlL on Windows or L on Mac toggles between transforming an object relative to world coordinates or the object's local coordinates. When in local mode, an L symbol appears to the lower-right of the object.

Pivot Tools

The Pivot tools give you full control over the points around which objects rotate and translate. See Pivot Tools for details.

Pivot Tools indicated in Model tab

Align Tool

The Align Tool button opens a set of tools for aligning objects or groups of objects along the X, Y, or Z axes. For more information, see Align Tool.

Align Tool indicated in Model tab

Part Insertion

The Part button inserts a new part into the workspace. Clicking the small dropdown arrow on the button lets you select either Block, Sphere, Wedge, Corner Wedge, or Cylinder. For more information, see Parts.

Part menu indicated in Model tab

Material Manager

The Material Manager window lets you apply and create custom materials for parts and terrain. See Materials for details.

Material Manager indicated in Model tab

Color Picker

Clicking the small dropdown arrow on the Color button reveals a hexagonal color picker and, by default, applies the chosen color to all selected parts. You can also apply a chosen color as a painting tool by toggling on Color Action as Tool and clicking specific parts in the 3D viewport.

Color button indicated in Model tab

For alternative ways to apply custom colors, see Coloring Parts.

Group Tools

You can group objects into a model by selecting them and clicking the Group button. This action has a default shortcut of CtrlG (Windows) or G (Mac).

Alternatively, you can group objects into a folder by clicking the small arrow next to the button and selecting Group as a Folder. This action has a default shortcut of AltCtrlG (Windows) or G (Mac).

To ungroup an existing model or folder, click the small arrow next to the button and select Ungroup. This action has a default shortcut of CtrlU (Windows) or U (Mac).

Group tools indicated in Model tab

Lock Tools

You can enable the Lock Tool by clicking the small arrow next to the Lock button and selecting Lock Tool. This action has a default shortcut of AltL (Windows) or L (Mac).

Once enabled, the tool operates as a "key" for both states — clicking on an unlocked object locks it, while clicking a locked object unlocks it.

To unlock all objects, click the small arrow next to the button and select Unlock All.

Lock tools indicated in Model tab

Anchor Toggle

The Anchor toggle controls whether the part will be immovable by physics. When Anchored, a part will never change position due to gravity, other parts collisions, overlapping other parts, or any other physics-related causes. This action has a default shortcut of AltA (Windows) or A (Mac).

Anchor toggle indicated in Model tab

Solid Modeling

The Solid Modeling section contains tools to create new geometry beyond the basic parts Roblox provides. For more information, see Solid Modeling.

Solid modeling tools indicated in Model tab
ToolShortcutDescription
UnionShiftCtrlG (Windows)
ShiftG (Mac)
Join two or more parts together to form a single solid union.
IntersectShiftCtrlI (Windows)
ShiftI (Mac)
Intersect overlapping parts into a single solid intersection.
NegateShiftCtrlN (Windows)
ShiftN (Mac)
Negate parts, useful for making holes and indentations.
SeparateShiftCtrlU (Windows)
ShiftU (Mac)
Separate the union or intersection back into its individual parts.

Physical Constraints

The Constraints section contains tools for creating physical Constraints between objects.

Constraints are categorized into two groups:

  • Mechanical Constraints — Constraints in this group behave as mechanical connections, including hinges, springs, motors, and ropes.
  • Mover Constraints — Constraints in this group apply force or torque to move one or more assemblies

Effects and Spawns

The Gameplay section tools allow you to insert beautiful effects like lights and particle emitters, as well as quickly insert a SpawnLocation into the 3D space.

Effects and Spawn tools indicated in Model tab
ActionDescription
EffectsCreates a new light or effect within the workspace or the selected object. The dropdown lets you select which type of effect to create.
