\b0 Command.cs\par
\pard\ltrpar\nowidctlpar\li360\kerning0 This file contains a class Command that implements the IExternalCommand interface, get selected slab, creates SlabShapeEditingForm and gets ExternalCommandData.\par
\par
\pard\ltrpar\nowidctlpar\qj SlabShapeEditingForm\kerning2 .cs\par
\pard\ltrpar\nowidctlpar\li360\kerning0 This file contains a class SlabShapeEditingForm which inherits from Form. This Form has a PictureBox show the geometry info of Slab and some button used to create vertex and crease. \par

\pard\ltrpar\nowidctlpar\qj\kerning2 SlabProfile.cs\par
\pard\ltrpar\nowidctlpar\li360\tx720\kerning0 This file contains a class \kerning2 Sl\kerning0 abProfile which calculates the geometry info of Slab. SlabProfile consists of methods Draw2D(), AddVertex() and AddCrease(). Draw2D() is used to draw \kerning2 Slab \kerning0 curves on the picture box, and AddVertex() and AddCrease() are used to create vertex and crease on slab.\par
\pard\ltrpar\nowidctlpar\qj\kerning2\par
LineTool.cs\par
\pard\ltrpar\nowidctlpar\li360\tx720\kerning0 This file contains a class named LineTool which provides some methods to draw lines on the form and store the data of drawn lines. It also provide method to draw new created vertex as rectangle\par
