Class 5 Homework [3]: Google SketchUp Tutorial 2

Surfaces need to be enclosed, erase a bounding edge and the surface is gone [2]

You can easily recreate a surface by drawing a new edge (healing a surface) [2]

1. Draw a closed loop of edges to create a surface, they must also be co-planar  [2]

2. SketchUp snaps to the RGB axis when drawing lines, they will turn into the color of the axis they snap to [2]

SketchUp uses Inferring to line up lines/edges for you, hover for 2 seconds over the pt. you want to line up with, then move back to the line you were drawing until you see a dotted line [2]

3. green dots indicate endpoints [2]

middle of an edge is a cyan dot [2]

anywhere else on a line is a red dot [2]

black dot is an intersection of two lines [2]

4. Always draw to and from existing edges [2]

Don't draw new edges over exisitng edges (example given of how to divide a square into 4 equal parts) [2]

Practicing Rule 1, co-planar shapes

Practicing Rule 2, Inferring

Practicing Rule 3, Inference Points: example of a midpoint

Practicing Rule 4, Drawing to/from existing edges, not over them
