Building Spatial Awareness: Intro

Goal: Build this rectangular prism in the app below.

Goal: Build this rectangular prism in the app below.

Note the prism above has 8 vertices (corners). If we position one of its vertices at (0,0,0), enter 7 other ordered triples (x,y,z) that can serve as locations for its other vertices.

NEXT STEPS:

Note the prism above has six faces. Lets construct other five faces of this prism that are not contained in the gridded plane above.  Once you're done plotting the 7 other vertices of your prism:
  • Press the TOOLS icon (left side).
  • Find and select the POLYGON Toolbar Image tool.
  • Use this tool to construct each face of the polygon. (When building a face, be sure you select vertices in a circular order and "close" the polygon with the first vertex you selected.)
  • If you want to move your 3D construction around select the MOVE Toolbar Image tool to turn off the POLYGON tool so you can.
  • Tip: RIGHT CLICK on any point and select "FIX OBJECT" to prevent that point from moving.

This quick silent demo below show how to do these steps described above.
