'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.&#x20;

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'.&#x20;

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://albertlidesign.gitbook.io/vr-beso/gui/modeling-page.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
