AI Technical Summary
The traditional modeling process from 2D engineering drawings to 3D solids based on DXF relies on manual operation, which is inefficient and lacks accuracy, and cannot efficiently and automatically parse DXF geometric information and reconstruct 3D models.
An automatic reconstruction method based on DXF from 2D engineering drawings to 3D solids is adopted. By reading DXF file information, geometric elements are identified and classified, bending line information is extracted, non-bending curves are processed using a bidirectional traversal algorithm, bending lines are expanded by combining sheet metal processing industry parameters, and connection line compensation and curve segmentation are performed to construct a 3D solid model.
It achieves high-precision 3D model reconstruction, solves the geometric discontinuity problem caused by bending line offset, ensures lossless conversion between 2D process data and 3D model and full-process data traceability, and improves modeling efficiency and accuracy.
