Introduction to Multilines

1. Introduction to Multilines Sacramento City College Engineering Design Technology Introduction to Multilines

2. Drawing Multilines • A multiline consists of between 1 and 16 parallel lines that act as one line. • The lines in the set of multilines are called elements. Introduction to Multilines

3. Drawing Multilines • Multilines are commonly used for drawing • Roads • Walls of buildings for architectural plans. Introduction to Multilines

4. Drawing Multilines • The MLINE command is accessed by: • Picking the Multiline button from the Draw toolbar • OR • Picking Multiline in the Draw pull-down menu • OR • Typing ML or MLINE at the Command: prompt. Introduction to Multilines

5. Drawing Multilines • Three commands relate to multilines: • MLINE. (ML) • MLSTYLE. • MLEDIT. Introduction to Multilines

6. Drawing Multilines • The MLSTYLE command • Allows you to create multilines. Introduction to Multilines

7. Drawing Multilines • The default multi-line style has: • Two elements (lines). • Continuous line type. • Is called STANDARD. Introduction to Multilines

8. Multiline Justification • Justification determines how the resulting lines are offset. Introduction to Multilines

9. Multiline Justification • Justification • Can be specified only once during a single MLINE command sequence and • Is based on a counterclockwise rotation direction. Introduction to Multilines

10. Multiline Justification • The justification options are • Top • Zero • Bottom • TOP is the default • The current value remains in effect until changed. Introduction to Multilines

11. Top Justification Introduction to Multilines

12. Zero Justification Introduction to Multilines

13. Bottom Justification Introduction to Multilines

14. Multiline Justification • To change the justification • Enter J at the first prompt • Enter the first letter of the desired justification • Top • Zero • Bottom Introduction to Multilines

15. Multiline Justification • The justification setting is stored in the AutoCAD CMLJUST system variable. Introduction to Multilines

16. Adjusting the Multiline Scale • The Scale option controls the multiplier for the offset values specified in the MLSTYLE command. • The multiplier is stored in the CMLSCALE system variable. Introduction to Multilines

17. Adjusting the Multiline Scale • When the scale is 1, the distance between multiline elements is equal to 1 times the offset distance. • If the offset distance is 0.5, the distance between multiline elements is 0.5 when the multiline scale is 1. • If the multiline scale is 2, the distance between multiline elements is 1 (0.5 x 2). Introduction to Multilines

18. Adjusting the Multiline Scale • For zero justification, • The multiline elements are offset 0.5 units on either side of the definition points picked. • Example: If the multiline scale is 2 • Top and Bottom justification = 2 units offset • Zero justification = 1 unit and -1 unit offset. Introduction to Multilines

19. Setting Your Own Multiline Style • ML Command Style option • Allows you to specify the current multiline style. • The style must be saved before it can be accessed. Introduction to Multilines

20. Setting Your Own Multiline Style • Using saved Multiline styles • Type: ML • Type: ST - to access the style option, • Type the known multiline style name. • A “?” lists all of the names of the multiline styles. • Typing a name of a multiline style that does not exist, the Load multiline style from file dialog box is displayed Introduction to Multilines

21. Introduction to Multilines

22. Setting Your Own Multiline Style • Multilines are stored in the acad.mlnfile library. Introduction to Multilines

24. Introduction to Multilines

25. Setting Your Own Multiline Style • You can load the multiline style from another file (not acad.lin). • Custom multilines can be purchased for AutoCAD. Introduction to Multilines

26. Defining Multilines Introduction to Multilines

27. Multiline Styles • Use the MLSTYLE command to define multilines. Introduction to Multilines

28. Multiline Styles • The MLSTYLE command can be accessed by: • Picking the Multiline Style entry in the Format pull-down menu • OR • Typing MLSTYLE at the Command: prompt. Introduction to Multilines

29. Multiline Styles • The Multiline options are: • Current: • Name: • Description: • Load... Button: • Save... button. • Add button. • Rename button. Introduction to Multilines

30. Introduction to Multilines

31. Multiline Styles • Current: Text box. • The Current: text box makes the specified multiline style current. • Specifying a different style changes the setting of the CMLSTYLE system variable. • Until you create a multiline style, the only style available is STANDARD. Introduction to Multilines

32. Multiline Styles • Name:Text box. • This text box is used to enter the name for a new style. • Description: Text box. • An optional description of your multiline style may be entered in this text box. Introduction to Multilines

33. Introduction to Multilines

34. Multiline Styles • Load... button. • This button allows you to load a multiline style from an external multiline definition file. • Save... button. • The Save... button is used to save a style to a file. Introduction to Multilines

35. Introduction to Multilines

36. Multiline Styles • Add button. • Pick the Add button after entering a multiline style name in the Name: text box. • This adds the multiline style name to the list of defined styles. • Rename button. • Pick this button to rename a multiline style. Introduction to Multilines
