1, first open the original image in STEP format.

2. Open the surface and find that the surface is flattened and opened. If you can't find the surface flattening, you can directly enter "Surface Flattening" in the search bar and double-click to open it.

3. Then select faces and lines according to the arrows in turn, and click OK.

4. Right-click the drawing, click Export to DXF/DWG at the arrow, and then click Save.

5. Click the check mark, and then click Save. Note that the dimension at this time is the external expanded dimension of the graph. If the middle layer is needed, it needs to be adjusted in CAD.

The main modules of SolidWorks:

1, part modeling:

SolidWorks provides unparalleled feature-based solid modeling function. Product design is realized by stretching, rotating, thin-walled features, advanced shell extraction, feature array and punching.

Through the dynamic modification of features and sketches, the drag-and-drop real-time design modification is realized.

The 3D sketch function generates 3D sketch paths for scanning and lofting, or paths for pipes, cables, lines and pipelines.

2, surface modeling:

Complex surfaces are generated by controllable tangent operations, such as scanning, lofting, filling and dragging with control lines. You can operate surfaces intuitively, such as trimming, extending, chamfering, sewing, etc.
