The sketching software developed in this thesis, is aimed to serve as an
intelligent design tool for the conceptual design stage of the mechanical design
process.
This sketching software, Sketch Pad for Windows, closely mimics the
traditional paper-and-pencil sketching environment by allowing the user to sketch
freely on the computer screen using a mouse. The recognition algorithm built into
the application replaces the sketch stroke with the exact CAD entity. Currently, the
recognition of two-dimensional design primitives such as lines, circles and arcs has
been addressed.
Since manufacturing requires that the design concepts be detailed, sketches
need to be refined as detailed drawings. This process of carrying design data from
the conceptual design stage into the detail designing stage is achieved with the help of
a convertor that converts the sketch data into DesignView (a variational CAD
software). Currently, only geometrical information is transferred from the sketching
software into DesignView.
The transparent graphical user interface built into this sketching system
challenges the hierarchial and regimental user interface built into current CAD
software. / Graduation date: 1995
