sketch
A two-dimensional curve drawing.
Details
A sketch is a set of two-dimensional curves. It can be generated by adding multiple curves to the sketch.
Example
curve c1 = <[8,0]> -> arc( <[0,0]>, 2PI )
curve c2 = <[4,3]> -> arc( <[3,3]>, 2PI )
curve c3 = <[-4,3]> -> arc( <[-3,3]>, 2PI )
curve c4 = <[5,-1.5]> -> arc_to( <[-5,-1.5]>, 5.5, false ) -> arc_to( <[5,-1.5]>, 5.2 )
sketch s = c1 - c2 - c3 - c4

Members
- vector front()
-
Returns the starting point of the curve, if this is defined. Otherwise it returns <[0.0, 0.0, 0.0]>.
- vector back()
-
Returns the end point of the curve, if this is defined. Otherwise it returns <[0.0, 0.0, 0.0]>.
