s1, responding to the customization operation executed by the uplink configuration interface, obtaining uplink basic service information, wherein the uplink customization parameter comprises the uplink basic service information, and the uplink basic service information comprises the following components: the type identifier of the blockchain is used for generating a uplink strategy of the NFT intelligent contract and corresponding to the uplink operation;
as an optional implementation manner, it is assumed that the above-mentioned method for saving a CAD metafile of a computer-aided design is applied to a scenario where a CAD platform saves a drawing. The uplink basic service information herein may be, but is not limited to, used to assist NFT smart contracts in uploading to the blockchain.
In particular, the indication parameters included in the uplink basic service information may be, but are not limited to, used to indicate whether NFT smart contracts corresponding thereto are to be generated for CAD metafiles. The type of blockchain included in the uplink basic service information may be, but is not limited to, a type identification corresponding to a blockchain (e.g., public blockchain, private blockchain, federation (industry) blockchain, etc.) that indicates that the NFT smart contract needs to be uploaded.
The uplink policy included in the uplink basic service information may be, but is not limited to, a policy for instructing the NFT smart contract to upload to the blockchain, including: the NFT smart contracts are uploaded to the personalization set of the blockchain, and the NFT smart contracts are uploaded to an architecture (such as a Client/Server architecture (Client/Server architecture, abbreviated as C/S architecture) or a Browser/Server architecture (Browser/Server architecture, abbreviated as B/S architecture)) adopted by the blockchain.
Further, the personalization settings of the NFT smart contract upload to the blockchain herein may be, but are not limited to, a device for indicating the timing of the NFT smart contract upload to the blockchain, including: semi-finished product winding, time dimension winding, and so forth.
For example, assuming that the engineer selects the semi-finished product to be booted, the engineer may preset the NFT smart contract corresponding to the partial content of the CAD metafile to be uploaded to the blockchain when the drawing of the partial content (e.g., a certain scale such as 50%, 80%) of the CAD metafile is completed. Then, in the event that the engineer completes the portion of the CAD metafile, the CAD client will automatically upload the NFT smart contract corresponding to the portion of the content of the CAD metafile onto the blockchain. Therefore, partial content of the CAD metafile can be automatically and timely protected, storage efficiency of the CAD metafile is further improved, safety of storage of the CAD metafile is improved, and experience of a user is improved.
Further, assuming that the engineer selects the finished product to be uploaded, the engineer may preset to upload the NFT smart contract corresponding to the CAD metafile onto the blockchain when all the drawing of the CAD metafile is completed.

And under the condition that the current time reaches the preset time, the CAD client automatically links the NFT intelligent contract corresponding to the CAD metafile. In addition, assuming that the engineer selects the time dimension uplink policy, the engineer may also preset the NFT smart contract corresponding to the CAD metafile to the blockchain within a specified preset period (e.g., every 1 hour). In other words, when the preset period is reached, the CAD client will automatically link up the NFT smart contract corresponding to the CAD metafile. And further, the high-efficiency and automatic protection of the CAD metafile finished product is realized, the security of CAD metafile storage is improved, and the experience of a user is improved.
It should be noted that, the NFT smart contract uplink operation and the CAD metafile save operation are performed simultaneously. In other words, the timing of the NFT smart contract is the timing of casting the NFT by the CAD metafile, and when the CAD client automatically links the NFT smart contract corresponding to the CAD metafile, the CAD client also performs a local operation for storing the CAD metafile. That is, the NFT intelligence contracts the strategies of semi-finished product up-chain, time dimension up-chain, etc., that is, the casting of semi-finished products, the casting of finished products, the casting strategy in the time dimension, which correspond to CAD metafiles NFT.

It should be noted that after obtaining the metadata for generating the NFT smart contract, the method further includes: and displaying NFT intelligent contract codes of the NFT intelligent contracts automatically generated by the secondarily developed CAD platform based on the metadata in a uplink configuration interface, wherein the codes comprise metadata (such as author information of the CAD metafile, attribute description information of the CAD metafile, storage links of the CAD metafile and the like) corresponding to the CAD metafile.
And S3, responding to the confirmation operation executed on the configured uplink customized parameters, and storing the uplink customized parameters.
Optionally, in this embodiment, before the confirmation operation performed in response to the uplink customization parameter completing the configuration, it may include, but is not limited to: upon completion of configuration of the uplink customization parameters, all of the uplink customization parameters that have been configured are displayed in the uplink configuration interface so that the engineer checks whether the uplink customization parameters are wrong.

Optionally, as an alternative, performing the uplink operation on the NFT smart contract that matches the CAD metafile generated according to the configured uplink customization parameters includes:
and under the condition that the uplink policy indication is based on the C/S architecture mode uplink, storing the NFT intelligent contract locally, and sending an interface calling instruction to a remote blockchain basic service through the CAD client, wherein the interface calling instruction is used for indicating to call a corresponding blockchain service interface to execute the uplink operation on the NFT intelligent contract.

In the embodiment of the application, the NFT casting of the CAD metafile is performed by adopting the mode of linking the C/S architecture mode, so that the technical effects of improving the storage efficiency of the CAD metafile in the computer aided design and improving the experience of a user are realized.

Alternatively, where a B/S architecture mode is employed for the uplink, the NFT plug-in of the CAD requires basic data collection and instruction receiving tasks (e.g., providing API services for blockchain base Service encapsulation), and in turn requests pre-developed NFT micro-Service components (which are deployed on a Software-as-a-Service platform that is native to the kubernetes-based cloud) via a hypertext transfer protocol (Hyper Text Transfer Protocol, abbreviated as HTTP), causing the NFT micro-Service components to store data and initiate operation of the remote blockchain base Service.
It should be noted that the difference between the design of the C/S architecture and the design of the B/S architecture is that most operations on the blockchain are concentrated on the CAD side or the microservice component side, where both schemes require local preservation of the NFT smart contracts.
In the embodiment of the application, the NFT casting of the CAD metafile is performed by adopting the mode of the B/S architecture mode uplink, so that the technical effects of improving the storage efficiency of the CAD metafile in the computer aided design and improving the user experience are realized.

In this embodiment, by accessing the uplink adapter in the CAD client, the engineer may choose to upload the NFT smart contract for the CAD metafile into any type of blockchain, regardless of whether the interface is adapted. And further, the technical effects of improving the storage efficiency of the CAD metafile, protecting the right of the CAD metafile and improving the experience of the user are achieved.
