3D-Printing Club: Detail Drawings

Use scale drawings to check parts and redraw designs.

Enlarged Details

All drawings show flat views of 3D-printed parts. Scales compare drawing length to actual length in the same units. For example, 3:1 means the drawing lengths are three times the actual lengths. Do not measure the printed pictures.

The club records measurements from one enlarged detail drawing. Which scale fits every row?
