Rollercoaster Projects

2. have an electric cord to bring the rollercoaster up backwards with support blocks behind it, then will drop forward go upwards then back down again, then will go through a loop and up to the last drop, then the electrical cord will stop the ride bring it up to the top of the drop and have the rollercoaster go the opposite direction and back to the start kinda like the bat at wonderland.
week before march break
mon- rollercoaster design
tues- finishing the rollercoaster
wed- adding the support to the coaster
thru- adding the scene for the coaster got half way tho
fri- sick

mar 22 - putting in my blogger what i got done

Engineering Drawing With CAD Application

Engineers: People who use technical means to solve problems. They design products, systems, devices, and structures to improve our living conditions.

Technical Drawings: a clear, precise language used in the design process for communicating, solve problems, quickly and accurately visualizing objects, and conducting.

92% of the design process is graphical
the remaining 8% is mathematics and written communications

Designing process includes
- problem Identification
- Preliminary Ideas
- Design Refinement
- Analysis
- Optimization
-Documentation

Implementation - service
- financing
- Marketing
- producing
- planning
- documention

TDJ4M – Test # 2 Review
Orthographic Drawing and AutoCAD
Study Lesson 1-3: Engineering Drawings
Orthographic Projection
 Three standard views – Front, Top, Right
 Isometric view – a 3-Dimensional representation of the part with depth lines drawn at 30° angles

Study Lesson 2-1: CAD/CAM Introduction
CAD – Computer Aided Design
 Advantages of CAD
o Easier creation and correction of drawings
o Better visualization of drawings
o Toolbox of drawing aids
o Quick and convenient design analysis
o Simulation and testing of designs
o Increased accuracy
o Improved filing
o Better communication with manufacturing
