Questions and Answers

What is the main difference between a line and a polyline?

  • A line cannot be drawn with endpoints, only a polyline can
  • A line can have two or more segments while a polyline can only have one segment
  • A line is not joined while a polyline is joined (correct)
  • A line is joined while a polyline is not joined

How can you change from single line segments to a polyline?

  • By using the Unjoin command
  • By using the Segment command
  • By using the Explode command
  • By using the Join command (correct)

What does the Explode command do in regard to polylines?

  • It unjoins polylines into individual line segments (correct)
  • It changes segments to lines
  • It draws multiple lines
  • It joins the line segments

Study Notes

  • The text describes various methods for creating geometric shapes in a 3D modeling software called Rhino.
  • The first shape drawn was an arc that is tangent to multiple curves. This involved selecting the curves and using the arc command to draw a tangent arc.
  • Following this, circles were created in various ways. One method involved using the "fit points" option to create a circle around a group of points. Another method involved drawing a circle around a curve.
  • Ellipses were also discussed, with two methods presented. The first involves defining the center and the two axes, while the second involves defining the diameter and then creating a clean, editable ellipse.
  • The text emphasizes the importance of understanding the type of geometry being created and the advantages of using certain methods over others for particular applications.
  • When drawing any kind of curves, the text advises keeping it simple by using the fewest number of control points possible and avoiding loops.
  • After a curve has been drawn, editing tips include moving control points by clicking and dragging or using the Point Edit flyout for more advanced controls, such as adding points to a curve.
