9. Orthographic Drawings
Tips:
Draw views in order: top → front → side
Draw lines where edges exist (changes in plane)
Show hidden edges using dotted lines
Solid lines trump dotted lines

10. Station 4: Computer-Aided Visualization
Workshop 1 Stations
Station 3: No-Look Pass
In pairs, one student wears a blindfold while the other student builds an object with 5 blocks
The blindfolded student holds the object and describes the three orthographic views out loud
The partner draws ONLY what is described by the blindfolded student
When finished, correct the drawing and switch roles
Repeat and practice, moving to larger objects
Station 4: Computer-Aided Visualization
Read Module 4 – Orthographic Views
Complete the orthographic views exercises
Station 1: Block Relay
Build an object with 8 blocks
Draw the three orthographic views
Then pass the object to a neighbor and repeat
Check drawings for accuracy with neighbor
Station 2: Workbook Drill
Individually, answer questions on ODD pages ortho1 to ortho24 on scrap paper
Check your answers with the answer key
Leave this slide up so students know what to accomplish at each station
