Q. The Spline option of the PEDIT command
  • (A) creates an arc-fit polyline joining each pair of vertices to convert a straight-line polyline into a curve.
  • (B) uses the vertices of the polyline as control points to create a curve approximating a B-spline.
  • (C) generates the linetype in a continuous pattern through the vertices of the polyline
  • (D) smoothes a polygon mesh surface.
