Part 1: Curves

Open a new Rhino File and practice the curves commands by completing the following steps. Organize your Rhino file so each step is clear. Use the Text command to label each step and the commands you used.

1. Make the specific footprint below.

• Commands: Polyline

2. Make 2 closed rounded curves using the various curve commands.
     •    Commands: Curve, InterpCurve, HandleCurve

InterpCrv command draws a curve through selected locations in space.

HandleCurve command draws illustration-program-style chained Bézier curves.

3. Make 2 closed curves using polygon, ellipse, or circle.
     •    Commands: Circle, Ellipse, Polygon

4. Make 2 open curves.
     •    Commands: Curve, InterpCurve, HandleCurve, Sketch

The sketch draws a curve by dragging the mouse

5. Import a picture and trace an image.
     •    Commands: Picture, InterpCurve

6. Pick one open curve, and one closed rounded curve and make three copies of each.
     •    Commands: Copy

7. Take at least 3 of your closed curves and overlap them to create a new shape.
     •    Commands: Move

8. Use split, delete, and trim to combine these curves into one open curve.
     •    Commands: Split, Delete, Trim, Join, Explode

The Explode command breaks objects down into components.

9. Take at least two curves and use various transformations make a pattern or composition.
     •    Commands: Move, Copy, Rotate, Mirror, Array, Scale, Offset, Fillet, FilletCorners

The Offset command copies a curve so that all locations on the copied curve are a specified distance from the original curve.

The FilletEdge command creates a tangent surface between polysurface edges with varying radius values then trims and joins the original faces to the fillet surfaces.

Part 2: Surfaces

Open a new Rhino File and practice the surfaces commands below by making two different surfaces for each command. Organize your Rhino file so each step is clear. You may want to use some of the curves you modeled in Part 1. Use the Text command to label each step and the commands you used.

2. PlanarSrf

3. EdgeSrf

The EdgeSrf command creates a surface from two, three, or four selected curves.

4. ExtrudeCrv

The ExtrudeCrv command creates a surface by tracing the path of a curve in a straight line.

5. ExtrudeCrvAlongCrv

The ExtrudeCrvAlongCrv command creates a surface by tracing the path of a curve along another path curve.

6. Loft

The Loft command fits a surface through selected profile curves that define the surface shape.

7. Sweep1

The Sweep1 command fits a surface through a series of profile curves that define the surface cross-sections and one curve that defines a surface edge.

Step.

Select cross-section curves in the order that the surface will pass through them.

Select a single rail curve.

8. Sweep2

The Sweep2 command fits a surface through a series of profile curves that define the surface shape and two curves that define the surface edges.

Step.

1. Select two curves as the rails.
2. Select cross-section curves in the order in which the surface will pass through them.

9. Revolve

The Revolve command creates a surface by revolving a profile curve that defines the surface shape around an axis.

10. RailRevolve

The RailRevolve command creates a surface by revolving a profile curve that defines the surface shape around a rail curve that defines the surface edge.

Part 3: Solids

Open a new Rhino File and practice the solids commands below by making two different solids for each command. You may want to use some of the curves and surfaces you modeled in Parts 1 and 2. Organize your Rhino file so each step is clear. Use the Text command to label each step and the commands you used.

1. Box

2. Cylinder

3. Sphere

4. ExtrudeCrv and Cap

5. Pipe

The Pipe command creates a surface with a circular profile around curves.

6. MoveFace

7. MoveEdge

8. OffsetSrf

The OffsetSrf command copies a surface or polysurface so that locations on the copied surface are the same specified distance from the original surface.

9. BooleanUnion

The BooleanUnion command trims the shared areas of selected polysurfaces or surfaces and creates a single polysurface from the unshared areas.

10. BooleanDifference

The BooleanDifference command trims the shared areas of selected polysurfaces or surfaces with another set of polysurfaces or surfaces.

11. Boolean Intersection

The BooleanIntersection command trims the unshared areas of selected polysurfaces or surfaces.

12. BooleanSplit

The BooleanSplit command splits shared areas of selected polysurfaces or surfaces and creates separate polysurfaces from the shared and unshared parts.

13. Using the surfaces and solids you modeled and the Boolean tools, make three solid shapes you find interesting.

Part4

This is a cube surface fluid model, the middle part of it is obtained by Boolean difference operation with three cylinders. It looks not bad. On top of it, there is a wave type texture, I like this texture, it looks beautiful. The only disadvvantage of this printed object is that it takes 13 hours to finish printing. I’m curious about some other printing algorithms.
