Question

history of engineering graphics
use the graphic organizer to capture at least 4 different time frames and an
inventor or related tool that was mentioned during the time frame.
time frame\tinventor or related tool
ancient times
medieval period
12th century\t
renaissance
period\t
19th century\t
20th century\tcollaborative modeling

Explanation:

Each time frame is paired with a key inventor or tool pivotal to engineering graphics development, based on historical records:

1. For the 12th Century (Medieval Period), the astrolabe was a critical precision drawing/measuring tool used for engineering and astronomical design.
2. During the Renaissance, Leonardo da Vinci advanced technical illustration through detailed, accurate engineering sketches of machines and structures.
3. In the 19th century, the pantograph was widely adopted to scale engineering drawings, a key tool for standardized design.
4. In the 20th century, collaborative modeling software (like early CAD tools and later cloud-based platforms) transformed shared engineering graphic workflows.

Answer:

Time Frame	Inventor or Related Tool
Renaissance Period	Leonardo da Vinci
19th Century	Pantograph
20th Century	Collaborative CAD Modeling Tools
