Preview Credit Policy
1. General Provisions
1.1 This policy governs the acquisition, usage, deduction, validity period, and consumption priority of preview credits for all users accessing 3D/AR preview features on the platform.
1.2 Preview credits are consumed when users:
Preview a 3D model,
Load an AR scene, or
Interact with other 3D content displays.
Each successful load counts as one preview, regardless of viewing duration or interaction depth. Usage is not restricted by region, SKU, SPU, or any product identifier.
2. Credit Sources and Package Types
Preview credits are categorized into three types, as recorded in the user’s account upon issuance or purchase:
| Type | Acquisition Method | Validity Period |
|---|---|---|
| System Gift | Automatically granted to eligible accounts | No expiration; valid until fully consumed |
| Bundle Bonus | Included as a bonus with a Modeling Coupon bundle | As specified in the bundle’s terms |
| Top-up Credit | Purchased separately as a standalone credit package | As specified in the purchase terms |
Note: The above examples are for reference only. Actual terms are governed by the applicable purchase agreement.
3. Usage Scenarios and Deduction Rules
| Usage Scenario | Deduction Rule |
|---|---|
| Clicking to preview a 3D model | –1 preview credit |
| Entering an AR scene | –1 preview credit |
4. Validity and Expiration Rules
4.1 System Gift credits have no expiration date and remain available indefinitely once granted.
4.2 Bundle Bonus and Top-up Credit packages are valid only for the duration specified at the time of purchase (e.g., 12 months).
4.3 Expiration handling:
Any credit package with a defined validity period will be automatically cleared at midnight (00:00 CST) on its expiration date.
⚠️ Correction: “24:00” is not standard in English time notation. Use midnight or 00:00.
5. Credit Consumption Priority
Credits are consumed according to the following priority logic:
Priority 1: System Gift Credits
— Consumed first in full, as they carry no expiration risk.Priority 2: Non-Gift Credit Packages (Bundle Bonus & Top-up)
— Among these, credits are consumed using a “first-expiry-first-out” (FEFO) rule:
• Packages with the earliest expiration date are used first.
• If multiple packages share the same expiration date, the one activated earliest is consumed first (“first-in, first-out”).
Example:
A user holds:Consumption order: System Gift → Bundle A → Top-up B.
