29. Dimension Rules Common Errors 29

30. Dimension Rules Acceptable Application 30

31. Text Two types of fonts –Shape fonts SHX Vector-based AutoCAD –TrueType fonts (TTF) Raster-based Windows Letter Height –General: 0.12", 3mm –Titles: 0.24", 6mm 31

32. Text Don't Use Name “Standard” Acceptable Fonts - Mechanical –NOT txt.shx –Romans.shx Acceptable Fonts - Architectural –Romans.shx –Blueprint font 32

33. Linetypes and Weights Hidden Line Conventions 33

34. Linetypes and Weights Center Lines and Marks –Often incorrect in AutoCAD 34

35. Linetypes and Weights Center Lines and Marks –Use DCE for proper marks and editing without exploding 35

36. Linetypes and Weights Circular Center Mark –ARRAY them yourself 36

37. Linetypes and Weights Lineweights –Object lines Thick (0.4mm - 0.5mm) –Other lines Thin (0.2mm - 0.25mm) –Architectural May have four to seven lineweights 37

38. AutoCAD Defaults 38

39. Applying Standards 39

40. Template Drawing Location 40

41. Use QNEW 41

42. Contents of Template File Layers –Colors, linetypes, lineweights –Layer filters, saved states Dimension Style Limits and Units Text Styles ( not STANDARD) General Block Definitions 42

43. Contents of Template File Views and Viewports Layouts for Each Sheet Size Default Plot Styles/Pen Styles System Variables (Not Registry) –AUPREC and LUPREC –LTSCALE, PSLTSCALE –MEASUREMENT –And so on 43

44. Layer Naming - Commercial Architecture AIA –Discipline –Major group –Minor group –Status –User defined Example A-WALL-DIMS-NEWW 44

45. Layer Naming - Residential Architecture Can use AIA Might Have Simpler Standard For Example FL1-DIM FL2-DIM FND-DIM 45

46. Layer Naming General Reserve Layer 0 for Defining Blocks Use Part-Based Layer Names for Assemblies Use Logical Field Names –Easier to manage with wildcards 46
