Interactions Menu

Provides users with different tools to define interactions in the VR experience.  


Grabbing Group

Make Grabbable

Makes selected object(s) grabbable in the scene. A grabbable object is an object that can be grabbed by a controller in a VR experience or using a desktop hands and can be moved from one place to another. 


Grabbable objects are highlighted clearly in the Scene Browser 

Grabbable objects are highlighted in the Desktop or VR viewing modes with orange highlight, as shown in the following image 


Make Grabbable Sequence

Grabbable sequences allow users to interact with 3D object(s) in VR by linking then to animation sequences. In the image below an animation to control the arm was saved as a sequence, then linked to the arm object using Grabbable Sequence. When the arm is grabbed in VR the path appears and the user can move the grabbed object along the path.


The following tutorial shows how to create and use Grabbable Sequence


Dynamics Group

Enable Physics

Enable physics makes the object simulate projectile motion, fall down to gravity, and collision with static and moving objects. Density, Friction, and Restitution coefficient and assigned in the physical properties section of the material properties.

The following tutorial shows how to use physics simulation in VR 

Make Climbable

With this feature selected objects in the scene can be made climbable such as ladders.  Just click Make Climbable and select the object you want. 

Check this tutorial for more about these two features. 

To adjust the Density and Restitution properties, which impact how objects behave during physics simulations, follow these steps:

1- Choose the material(s) applied to the physics objects.
2- Navigate to the Physics properties.
3- Update the Density and Restitution values according to the instructions illustrated in the accompanying image.


Training builder gives the user the option to enable/disable physics on physics objects in the VR experience.

The response for doing that is shown in the following image;


Clipping Plane Group


Create Clipping Plane

Can be used to view a section of the model or to hide specific objects in the scene. Users can control objects to be affected by each clipping plane. The user can select objects each clipping plane will act on.

The clipping plane can be static or it can be animated showing clippable objects as it moves.

Add Object(s) to All Clipping Planes

Also known as Section Plane in VR, it can be static, animated, grabbable, and turned on/off dynamically. 
From VR Clipping Plane Tab in the Properties Panel, the user can select to show or hide the clipping plane. The direction of the clipping plane normal determines the clipped section of the model.


Disassembly and Docking Group

Make Dock and Target

Dock is the static object, and Target is the (grabbable) moving one, so Target needs to be made Grababble first. After selecting this function the user will be asked to Select Dock Node, then to Select Target Node, and last to Configure object orientation.

In the VR experience, the user grabs the Target and when it is left (grab ends) while it is intersecting with the Dock, it is moved to the docking target's predefined position.

Remove Dock and Target

Selecting this function will prompt the user to Select Dock Node, and Select Target Node then the relation will be removed

The following tutorial shows how to create Dock and Target interaction in SimLab Composer.

Manage (Dis)Assembly Process

In case the assembly/disassembly process is linear, which means it goes in a defined order this function can be used. It simplifies the process and makes it move in a very specific scenario. Highlights will guide the user throughout the assembly/disassembly process with ease and without any confusion. Green highlight object in an assembly refers to the currently available part of the system that can be removed. Yellow highlight indicates that the object can be grabbed.





Blue highlight in the assembly indicates that the object can be placed there.

Press Right Mouse to toggle the hand. The hand has a fixed position at the center of the view, but can be moved away or closer using the mouse scroll.

The assembly management interactions, and settings:

  • Plus button: Adds the selected node (from the 3d Area) to the disassembly diagram. If a disassembly graph node is selected, it will become the parent of the newly added node.
  • Ladder button: Change the parent of selected disassembly graph nodes, a graph node must be selected before clicking this button, and the graph node selected afterward will become the new parent - or - if a blank space is selected, the graph node will become independent (with no parent).
  • Red Minus button: removes a node from the graph.
  • Create new: create a new disassembly diagram.
  • Rename: change the name of the disassembly diagram.
  • Delete: remove the disassembly.

Note: Training Builder can be used for creating a more open assembly/disassembly process. It can be used to define the logic for the processes, giving the user more control without forcing her/him to adjust the model structure in Scene Browser or go through a single path of exclusion.

Industries Solutions

SimLab Composer is continuously adding new features to make the experience of its users more joyful, and easier.

Door/Cabinet Animation

Automatically creates an animation for an object depending on its type. This can be useful for scenes with multiple objects of the same type. There are two main methods for defining which objects to animate:


Object Selection

With this method, the user will manually select the components in the scene to create an animation for.
This method is suitable for scenes with a small number of objects. Check the following tutorial on automatic animation for Doors / Cabinets using the Object Selection Method

Object Name

With this method, the user will type in the name of the components, and SimLab Composer will automatically find them in the scene and list them.
This method is more suitable for scenes with a large number of objects to animate. Check this tutorial on automatic animation for Doors / Cabinets using the Object Name Method

Doors and Cabinets Settings
  • Send animation to timeline; Enabling this option sends the created animation as keyframes to the Animation Timeline. This can be helpful when you intend to combine multiple animations or modify the animation further.
  • Create animation Sequences; This option creates separate animation sequences for each object, those sequences can then be used in VR.
  • Animation sequence naming convention; The user can select the naming method for the sequence.  
  • Attach sequences; This makes the scene ready to be used in a VR experience. Sequences can be applied as Actions (executed when the user clicks on a door or panel) or as Grabbable Sequences (the user can open or close interactively in the VR viewer) 
  • Create reversed versions; Reversed version of animation allows the object to go back to its original state. For example, if you have created an animation for a door opening, a reversed version of the door closing will be automatically created.


Visualize Scene Options

Visualize scene options (scene states and animation sequences) by displaying them as entities in a 3D world for easier and more practical VR experiences. Check this tutorial on how to visualize scene options in VR.


Press "3" on your keyboard in VR Viewer to show available Pins, "LBUTTON" to select Scene States/Animation Sequences that appear as entities from the Pins.


1 Select a Scene Node from the Objects Tree or from the 3D area, then click this option to add a Pin to the selected node, showing its scene states if interacted by the user in SimLab VR Viewer. 
2 Remove a Trigger and eliminate any associated pins and scene options.
3 The list of Triggers.
4 Activates Scene States library to drag-and-drop Scene States from it into Pin nodes.
5 Activates Animation Sequences library to drag-and-drop Animation Sequences from it into Pin nodes.
6 Add a new Pin to the selected node to hold other scene options chosen by the user. Once added, either Scene States or Animation Sequences from their corresponding libraries can be dragged and dropped into it.
7 Remove the selected Pin node from its diagram.
8 Scene States/Animation Sequences can be dragged-and-dropped here from their corresponding libraries.
9 Added Scene States/Animation Sequences
Visualize Scene Options - Step by step
  1. Create multiple Scene States/Animation sequences (at least two), for a 3D model.
  2. From the Interactions menu click Visualize Scene Options.
  3. Select the object for which to make a list, Ex: Bedside Table, select the table model then Add a Trigger by clicking image-1639851544234.png
