Then, we can exchange the editable 3D models from the smart device to the commercial CAD systems using
MPA. Currently, the MPA method can support the export of meshes
from CAD only (one-way exchange), as it is difficult to convert the
mesh data into a parametric feature-based CAD model . Although 3D models are created with polygonal meshes in this research, the system records the modeling command sequence to
a macro file every time. Conversion from the mesh model of the
smart device to a commercial CAD model is thus fully possible
