  3. The DIMLINEAR Command EDT 310 - Chapter 18 - Basic Dimensioning Practices

  4. DIMLINEAR Command • Use DIMLINEAR command for • Length • Width • Depth • Use DIMLINEAR for • Linear dimensions – (X,Y, Z) • Horizontal • Vertical • Slanted surfaces EDT 310 - Chapter 18 - Basic Dimensioning Practices

  5. DIMLINEAR Command • All dimension components are placed automatically by AutoCAD. • Extension lines. • Dimension lines. • Dimension text and arrowheads. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  6. DIMLINEAR Command • To DIMLINEAR command: • Pick the LinearDimensionbutton on the Dimension toolbar. • OR • Pick Linear from the Dimension pull-down menu. • OR • Type DLI or DIMLINEAR at the Command: prompt. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  7. DIMLINEAR Command • Command Sequence: Command: DLI or DIMLINEAR Pick First extension line origin. Pick Second extension line origin. Pick Location of dimension. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  8. First Extension Point EDT 310 - Chapter 18 - Basic Dimensioning Practices

  9. Second Extension Point EDT 310 - Chapter 18 - Basic Dimensioning Practices

  10. Dimension Location EDT 310 - Chapter 18 - Basic Dimensioning Practices

  11. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  12. DIMLINEAR Command • When picking extension line origins: • Use one of the OSNAP modes for accuracy. • ENDpoint is a good one to use. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  13. DIMLINEAR Command • The DIMLINEAR command allows you to generate dimensions that are • Horizontal. • Vertical. • Aligned with a slanted surface. • Rotated at a specified angle. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  14. DIMLINEAR Command • Command: DIMLINEAR • The following prompt appears: Dimension line location (Mtext/Text/Angle/Horizontal Vertical/Rotated) • Notice submenu choices • Mtext • Text • Angle • Horizontal • Vertical • Rotated EDT 310 - Chapter 18 - Basic Dimensioning Practices

  15. DIMLINEAR Command • Dimension line location • Is the default option selection. • Click the location where you want the dimension line. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  16. DIMLINEAR Command • Mtext • Accesses the Multiline Text Editor. • The << >> (Chevrons) indicate the current dimension value. • The < > is an intelligent value. • Normally, you should NOT delete the < >. • If you want the dimension changed, delete < >. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  17. MTEXT Option EDT 310 - Chapter 18 - Basic Dimensioning Practices

  18. DIMLINEAR Command • Text (Uses DTEXT) • Uses the Command Line to change the dimension text. • Angle • Allows you to change the dimension text angle. • Horizontal • Sets dimensions to horizontal distances only. • Vertical • Sets dimensions to vertical distances only. • Rotated • Allows you to change the angle for dimension line. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  19. Text Option chosen EDT 310 - Chapter 18 - Basic Dimensioning Practices

  20. Angle EDT 310 - Chapter 18 - Basic Dimensioning Practices

  21. Vertical Horizontal EDT 310 - Chapter 18 - Basic Dimensioning Practices

  22. Rotated EDT 310 - Chapter 18 - Basic Dimensioning Practices

  23. The DIMALIGNED Command EDT 310 - Chapter 18 - Basic Dimensioning Practices

  24. Dimensioning Angled Surfaces • DIMALIGNED • Use for dimensioning a surface drawn at an angle. • DIMALIGNED • functions similarly to the DIMLINEAR command • aligns dimension lines with the surface. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  25. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  26. The QDIM Command EDT 310 - Chapter 18 - Basic Dimensioning Practices

  27. The QDIM Command • For DLI and DAL, • You must pick the extension line origins. • QDIM • Lets you pick a geometry • Circle, Rectangle, etc. • Extension line origins are AUTOMATICALLY selected. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  28. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  29. The DIMANGULAR Command EDT 310 - Chapter 18 - Basic Dimensioning Practices

  30. DIMANGULAR Command • Use DIMANGULAR command to • Dimension the included angle of an arc. • The arc’s center point becomes the angle vertex and • the two arc endpoints are the origin. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  31. Endpoint Origin Endpoint EDT 310 - Chapter 18 - Basic Dimensioning Practices

  32. DIMANGULAR Command • Use DIMANGULAR command to dimension part of a circle. • First pick point on a circle becomes the endpoint of the first extension line. • Second pick point becomes the endpoint of the second extension line. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  33. Endpoint Origin Endpoint EDT 310 - Chapter 18 - Basic Dimensioning Practices

  34. DIMANGULAR Command • Access the DIMANGULAR command by: • Pick the AngularDimensionbutton on the Dimension toolbar • Pick Angular in the Dimension pull-down menu • Type DAN or DIMANGULAR at the Command: prompt. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  35. DIMANGULAR Command • If there is enough room, AutoCAD will • Place the • Dimension text • Dimension line arc, and • Arrowheads inside the the extension lines. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  36. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  37. DIMANGULAR Command • If there is not enough room AutoCAD will • Place the arrowheadsoutside and • Place the numberoutside the dimension lines. • If space is very small, ALL will be placedoutside. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  44. Datum Dimensioning DIMBASELINE EDT 310 - Chapter 18 - Basic Dimensioning Practices

  45. Datum Dimensioning • In Datum or Baseline dimensioning, dimensions originate from commonsurfaces, centerlines or center planes. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  46. Datum Dimensioning • Datum Dimensioning is commonly used in mechanical drafting because each dimension is independent of the others. • AutoCAD refers to Datum Dimensioning as DIMBASELINE or DBA EDT 310 - Chapter 18 - Basic Dimensioning Practices

  47. EDT 310 - Chapter 18 - Basic Dimensioning Practices

  48. Chain DimensioningDIMCONTINUE EDT 310 - Chapter 18 - Basic Dimensioning Practices

  49. Chain Dimensioning • Chain dimensioning • Is rarely used in mechanical drafting. • has less accuracy, since each dimension is dependent on the previous dimensions. EDT 310 - Chapter 18 - Basic Dimensioning Practices
