'New' button: Remove the current sculpted model and create a new sculpting space.

'Draw' button: Launch the sculpting brush to draw 3D shapes. A green spherical brush stroke will appear in front of the right controller. The brush stroke size is adjustable by manipulating the thumbstick on the right controller. Pressing the right trigger creates a spherical shape as large as the brush stroke.

'Erase' button: Launch the sculpting brush to erase 3D shapes. A red spherical brush stroke will appear in front of the right controller. The brush stroke size is adjustable by manipulating the thumbstick on the right controller. Pressing the right trigger removes a spherical shape as large as the brush stroke.

'Create' button: Create a cubic design domain. The domain size is adjustable by manipulating the thumbstick on the right controller. The default size is the boundary of the sculpted model.

'Import' button: Open the 'Save' panel to import an existing 3D model from external CAD software. Users can access the files and folders from the connected desktop. Currently, only .obj or .sd files can be imported.

After clicking the 'Check' button, users can select the imported model to be imported as 'Mesh model', 'Sculptable model', 'Design domain model', 'Load model', 'Support model', 'Solid model', and 'Void model'. Then, users can click the 'Open' button to determine the position and scale of the imported model by moving the right controller.

'Export' button: Export the existing models, including the sculpted model (.sd), the topologically optimized model (.obj), elemental sensitivity numbers (.esen) and nodal sensitivity numbers (.nsen). The files will be automatically saved in 'C:\Users\AppData\LocalLow\<username>\iBESO-VR\Solution_n'. For each design iteration, a new folder named 'Solution_n' is created. For example, the folder of the first iteration is saved in 'Solution_1'.
