1. Chapter 7 Computer-Aided Design and Drafting in Architecture 2D vs. 3D
3 Advantages/ Disadvantages

2. Intro to CADD & BIM What is CADD or CAD CADD-_________________
What does BIM require?

3. Architectural Software Packages
Autodesk
AutoCAD
REVIT
Revit MEP, Structure
3DS max
Civil 3D
ArchiCAD
Google Sketch Up
SoftPlan
Chief Architect
MacDraft Pro
Architectural Software Packages

4. What can CAD never replace?
The computer aids in the design process, but creativity remains with the designer
Spend time planning before using the computer
Repetitive tasks are handled more effectively
Copy and Paste
Minor Changes to plans
Symbols and Blocks
Scaling
Stretching
Layers
Revisions
Editing

5. Advantages of CAD? Time needed for creativity is increased
Research in field
Walking jobsites
Parade of Homes
HBA meetings
Work is more accurate
Layers are used so several designs can be seen together

6. CAD Layers Divide layers among unique features Name Color Line type
Line weight
Plot Y/N

7. Why should I use layers?

8. The future is here today with CADD
Virtual software is used to give the appearance of reality
Walk through shows the building through a camera
Fly through shows the building like actually walking through it.

9. CAD in Architecture
What different views or drawings are used?
How is this architecture being used?

10. How work in Architecture is Accomplished
Work can be shared through a local network or over the Internet
Communication is key to design coordination
Files can be easily updated and managed from remote locations
Redlines outsources to India

12. CADD Symbols Inserted as Blocks
Common symbols increase design productivity

13. CADD Symbols Inserted as blocks
Unique CADD symbols can be created by using the BLOCKS or WBLOCKS command
AutoCAD’s Design Center and Tool Palettes conveniently store symbol libraries

14. CADD Graphics Conventions
Line color – aid in clarity and visualization and layer management
Text Fonts – closely represent an artistic style found in many manual drawings
Stylus BT
Archstyle
City Blueprint

15. U.S. National CAD Standard
Group of agencies develop a single CADD standard for the U.S.
U.S. National CAD Standard (NCS)
Allows consistent and streamlined communication among owners, architects and designers, and construction teams
Can result in reduced costs
AutoCAD and MicroStation were selected as primary applications

16. Uniform Drawing System
Construction Specifications Institute (CSI)
Uniform Drawing System modules
Standards, guidelines, and other tools for organizing and presenting architectural information
Based on flexibility, consistency, and linking
Provides a framework for facility model
Adopted by the U.S. National CAD Standard

17. Drafting Conventions
Provide a standard format for graphic and text content on drawings
NCS conventions include guidelines for:
Consistent drawing placement
Consistent orientation of dimensions, line representations, and drawing scales
NCS defines scale as:
Ratio of measuring units expressing a proportional relationship between a drawing and the full-size item
Drawing Scales:
Floor Plans =
Roof Plans=
Elevations=
Interior Elevations=
Full Sections=
Wall Sections=
Stair Details=
Details=

18. CADD Graphics Standards
Architectural drafting
A graphic language made up of features
Line weights and types
Text styles and fonts
Dimensioning
Terms and abbreviation
Notes on drawings
Architectural CADD symbols
Terms and Abbreviations
CLG SH SL

19. CADD Graphics Standards
CADD symbols/ Hatching
Reference symbols
Object symbols
Material symbols
