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
A smiley contour sketch.
Example
s.replace( 3, rotation( <[0,-3]>, <[0,0,1]>, PI ) >> s.element(3) )
make extrusion( s, <[0,0,1]> )
Result of the second example illustrating the use of the replace and element members.
Casts To
Members
- int length()
-
Returns the number of elements (i.e. curves) the sketch contains.
- curve element( int n )
-
Returns the element with index n.
- void replace( int n, curve c )
-
Replaces the element with index n of the sketch with a new curve c.
- selectbox min_bbox()
-
Returns the axis-aligned minimum bounding box of the sketch.
