What is preview?
Preview function will help you visualize the processing effect through a virtual screen after setting the parameters, ensuring that your parameter settings meet expectations and avoid problems during the machining process.
The preview framework includes:
- Processing Effect Simulation: Based on the Processing parameters you set, the system will display a 3D effect that closely resembles the finished product for your reference.
- Intelligent Inspection: The system will automatically check your machining parameters and alert you to any errors or improper settings that may affect the processing outcome. For example, if your cutting parameters do not meet the requirements, the system will prompt you with a message such as "may not cut through."
Preview supported modes include:
- Laser plane processing
- Rotary attachment processing
- Relief processing

How to Access
- Entering Preview: When your device and mode support it, you will see a "Preview" button in the bottom-right corner of the interface. Click this button to enter the preview screen.

- Unsupported Devices/Modes: If your current device or mode does not support the preview function, the "Preview" button will be hidden, and you will not be able to enter the preview.

- Missing Preview Data: In some cases, the system cannot perform an effect simulation, and the button will be disabled. You can use "Experience Mode" to view a simulated effect, which uses standard parameters for display.
- No Parameter Matrix: If the material you selected lacks a preset parameter matrix, the system cannot perform a simulation and requires this data to be added.
- No Material Data: We have not yet prepared the preview data for this material, so we are temporarily unable to provide a simulation.
- Custom Materials: Custom materials currently do not support simulation.

Preview Interface
You are now viewing the pre-processing preview interface, which helps you visualize the processing effect before you begin and provides smart detection suggestions.

Here is a description of the functions of each part of the interface:
- Preview Area: Located at the center of the interface, it displays your processing model and its simulated effect. In this area, you can view the object being previewed and the expected processing result.
- Smart Detect: In the panel on the right, the system will check your set processing parameters and provide relevant suggestions and warnings. You can see if there are any parameters that need to be adjusted.
- Toolbar: Zoom in and zoom out buttons support for zooming in multiples: 10%~800%. You can click restore button to restore and fit the screen.
You also can interact with the 3D preview in the following ways:
- Left mouse button + drag (one-finger operation on touchpad): Rotate freely
- Right mouse button + drag (two-finger operation on touchpad): Pan the view
- Scroll wheel: Zoom in and out

Cutting Effect: When a graphic can be successfully cut, the element can be displayed in layers (exploded view). Clicking on the model enters close-up mode; clicking on an empty area exits.

The system provides tips based on your settings to help you optimize your parameters. Current tips include:
May Not Cut Through: If the system determines that the set cutting parameters may not cut through the material, it will display a "Current parameters may not cut through" warning, reminding you to adjust the parameters.

Simulation requires experimental data. In the absence of experimental data, we cannot provide a simulated view. In this case, you will see an "Unsupported" status, and the image will show a zebra pattern:
Unsupported: If you see a striped pattern, it means that some elements cannot be simulated for a processing effect. This may be due to abnormal processing parameters; please recheck them to ensure a good processing result.
Other Notes
Network Issues:
- If your network is unstable or disconnected, the system will display a "Network anomaly, loading failed" message and prompt you to check your network connection.
- If the network disconnects during loading, the system will try to show the preview effect that has already loaded. If loading fails, a failure message will be displayed.
