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 2
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 Advantages of CAD? CAD Layers Divide layers among unique features Name Color Line type Line weight Plot Y/N 3
Why should I use layers? 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. 4
CAD in Architecture http://vodpod.com/watch/1937089-city-creek-projectdowntown-salt-lake-city-virtual-tour What different views or drawings are used? How is this architecture being used? 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 5
CADD Symbols Inserted as Blocks Common symbols increase design productivity 6
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 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 7
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 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 8
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= 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 WIC AFF DW MW NIC Notes General notes Notes Keynotes 9
