Using Imported 2D CAD Data
You can use legacy 2D CAD data by importing it into SolidWorks and you
can convert 2D CAD drawings into 3D models.
You can import
2D CAD .dxf
and .dwg files
to part or drawing documents with the DXF/DWG Import Wizard. Once in SolidWorks,
you must attach the dimensions and constrain the relations (the Constrain All command constrains
the basic geometry of imported sketches).
You can export
SolidWorks drawings to DXF/DWG files, including mapping objects to layers
Layers in imported 2D CAD drawings are retained in SolidWorks. You can
the layers in SolidWorks drawings when exporting.
You can import blocks from 2D CAD software, edit the blocks, save them,
insert instances in SolidWorks drawings, and so on.
2D to 3D Conversion
You can import a 2D drawing into a sketch in a SolidWorks part, extract
views into separate sketches for extruding into a base feature, then continue
to add features. The 2D to 3D conversion process is usually
faster than redesigning the part in SolidWorks.
