Lec 1: Getting Started (Ch1) 2D Construction (Ch2)
Chapter 1• Toolbars• Command Line• Command Tools• Drawing Units• Drawing Limits• Grid and Snap
Toolbars
• R-click on a toolbar to see which are active• Turn off and on toolbars • Move them around
Commands and Tools
• Command line– at bottom where you will enter commands– Resize
• Command Tool– hover over icon on toolbar– name of command pops up– Can use mouse or command line to access tool
Starting a new drawing• New drawing tool, File>New, type ‘new’• Select Template:
– acad for inches and ANSI dimensions– acadiso for millimeters and ISO dimensions
• Name: File>SaveAs .dwg extension
Starting a new drawing (cont)
• Units: Format>Units – choose type (Arch/Engr/Dec) and precision
• Limits: (turn on grid) Format>DrawingLimits – change to 8,5– Zoom All
• Grid and Snap– Tools>Drafting Settings can modify
Sample Problems
Sample Problems
• Ex1-2– Decimal units– Drawing limits = 594,420– Grid = 25– Snap = 12.5
Chapter 2
• Line—Random (DYN off) – Click mouse, c(lose) or enter when done, R-click repeat
• Erase—select individual or window group• Line—Snap (Grid and Snap to 0.5)• Line—Entering coordinates
– Type in 4,5 (enter) 3,6 …• Line—Dynamic Input
– enter distance (tab or <) angle• Construction Line
Chapter 2 (cont)• Circle
– Center Point and Radius or (d) Diameter– Two points: 2p then end points of diamter– Three points: 3p then enter 3 points– TTR: first draw 2 lines, then Circle, ttr, click on each, specify radius
• Circle Centerlines: – Bring up Dimension Menu, click Center Mark and a circle– Then select Dimension Styles (on R) and Modify, Sybmols/Arrows, Check line
• Polyline• Spline• Ellipse• Rectangle• Polygon
Chapter 2 (cont)
• Point• Text• Move• Copy• Offset• Mirror• Array• Rotate, trim, extend, break, chamfer, fillet, table
