Description

Technical Field

[0001] This invention relates to a method for viewing assembly information based on a 3D model. Background Technology

[0002] In ship design, the data linking between 2D engineering drawings and 3D models is crucial. If the 3D hull model cannot directly access information from the 2D production drawings, then any design modifications require manual updates to the 2D drawings. This leads to repetitive work, is prone to human error, and increases costs in both the design and manufacturing processes. Furthermore, the lack of a direct data link may prevent timely access to the latest design information during production, impacting efficiency. In terms of quality control, the absence of a direct data link can result in inconsistencies between 2D drawings and 3D models, affecting the accuracy and efficiency of quality inspection.

[0003] Therefore, a method for viewing assembly information based on a 3D model is provided. Summary of the Invention

[0004] To address the aforementioned problems in the existing technology, this invention provides a method for viewing assembly information based on a 3D model, which enables the retrieval of two-dimensional production drawings through a 3D model.

[0005] The technical solution to achieve the above objectives is:

[0006] Methods for viewing assembly information based on 3D models include:

[0009] Step S3: Record the correspondence between the specific location and annotation of each component and the assembly drawing, store the yacht hull model and the corresponding hull assembly drawing in the same database, and establish an index relationship;

[0010] Step S4: Set hyperlinks or bookmarks for each part of the yacht hull model, pointing to the corresponding two-dimensional drawings. By clicking on the part of the yacht hull model, you can jump to the corresponding production two-dimensional drawings and view the corresponding assembly drawing information.

[0011] Preferably, in step S1, the attribute information includes, but is not limited to, component name, number, version, description, material, size, weight, and design date.

[0012] Preferably, in step S2, the basic structure of the frame model includes, but is not limited to, rib plates, keels, sidewalls, and reinforcing bars.
