Чтение книги онлайн.

СКАЧАТЬ 6 : Customizing the AutoCAD User Interface for Mac In this chapter, you'll learn how to customize the elements and display of the AutoCAD user interface on Mac OS. The Customize dialog box allows you to create and manage the tools displayed by the AutoCAD user interface.

       Chapter 7 : Creating Tools and Tool Palettes In this chapter, you'll learn how to create and customize tool palettes in AutoCAD on Windows. Tool palettes allow you to create a visual set of tools that can be used to insert blocks, start commands, or even hatch a closed area. Tool palettes are available on Windows only.

       Chapter 8 : Automating Repetitive Tasks In this chapter, you will learn how to create scripts and action macros to automate repetitive tasks. Script files and action macros allow you to combine multiple commands into simple logical sequences without needing to know a programming language. Action macros are supported on Windows only.

       Chapter 9 : Defining Shapes, Linetypes, and Hatch Patterns In this chapter, you will learn how to create custom shapes, linetypes, and hatch patterns that you can use to control the way line work appears in a drawing. The AutoCAD install provides a limited number of standard shapes, linetypes, and hatch patterns. You can extend the standard definitions by creating your own shapes, linetypes, and hatch patterns for use in your drawings.

       Chapter 10 : Using, Loading, and Managing Custom Files In this chapter, you will learn how to use, manage, and migrate custom files. After you have spent the time customizing AutoCAD, all you have left to do is deploy and manage your files.

Part II: AutoLISP: Productivity through Programming

       Chapter 11 : Quick Start for New AutoLISP Programmers In this chapter, you'll get an introduction to the AutoLISP programming language. I begin by showing you how to enter AutoLISP expressions at the Command prompt and execute standard AutoCAD commands. After that, you are eased into some basic programming concepts that allow you to perform conditional tests and repeat expressions. The chapter wraps up with creating and loading an AutoLISP file into the AutoCAD program.

       Chapter 12 : Understanding AutoLISP In this chapter, you'll learn the fundamentals of the AutoLISP programming language. AutoLISP fundamentals include a look at the syntax and structure of an expression, how to use a function, and how to work with variables. Beyond just syntax and variables, you learn to use AutoCAD commands and group multiple AutoLISP expressions into custom functions.

       Chapter 13 : Calculating and Working with Values In this chapter, you'll learn to work with mathematical and string manipulation functions. Math functions allow you to perform basic and advanced calculations based on object values or a value that the user might provide, whereas string manipulation functions allow you to work with text-based values. Both numeric and textual values are used when creating or manipulating objects, adding annotations to a drawing, or displaying a message to the end user. Based on how the values are used, numeric values can be converted to strings and strings can be converted to numeric values.

       Chapter 14 : Working with Lists In this chapter, you'll learn to work with the list data type. Lists are used throughout AutoLISP to provide 2D or 3D coordinate values or to define an object stored in a drawing.

       Chapter 15 : Requesting Input, and Using Conditional and Looping Expressions In this chapter, you'll learn to request input from the user, use conditional statements, and repeat expressions. Requesting input allows you to get values from the user and then use those values to determine the end result of the program. Conditional statements enable a program to make choices based on known conditions in a drawing or input from a user. After you understand conditional statements, you will learn to use them in conjunction with looping expressions to execute a set of expressions until a condition is met.

       Chapter 16 : Creating and Modifying Graphical Objects In this chapter, you'll learn how to create, modify, and attach extended data to graphical objects using AutoCAD commands and AutoLISP functions. Graphical objects represent the drawing objects, such as a line, an arc, or a circle, that are displayed in model space or on a named layout. When modifying objects, you can choose to step through all the objects in a drawing or let the user select the objects to be modified. Extended data allows you to store information with an object that can be used to identify the objects your program creates or link objects to external database records.

       Chapter 17 : Creating and Modifying Nongraphical Objects In this chapter, you'll learn how to create and modify nongraphical objects using AutoCAD commands and AutoLISP functions. Nongraphical objects are used to control the appearance of graphical objects and store settings that affect the behavior of features in the AutoCAD program. Drawings support two different types of nongraphical objects: symbol table objects and dictionaries.

       Chapter 18 : Working with the Operating System and External Files In this chapter, you will learn how to work with settings and files stored outside of the AutoCAD program. Settings can be stored in the Windows Registry and Plist files on Mac OS, and they can be used to affect the behavior of the AutoCAD program or persist values for your custom programs between AutoCAD sessions. Files and folders stored in the operating system can be accessed and manipulated from the AutoCAD program, which allows you to set up project folders or populate project information in the title block of a drawing from an external file.

       Chapter 19 : Catching and Handling Errors In this chapter, you will learn how to catch and handle errors that are caused by an AutoLISP function and keep an AutoLISP program from terminating early. AutoLISP provides functions that allow you to trace a function, see arguments as they are passed, catch an error and determine how it should be handled, and group functions together so all the actions performed can be rolled back as a single operation.

       Chapter 20 : Authoring, Managing, and Loading AutoLISP Programs In this chapter, you will learn how to store AutoLISP code statements in a file, load and manage AutoLISP files, and deploy custom programs with plug-in bundles. Storing AutoLISP code in a file allows for its reuse in multiple drawings. When you load an AutoLISP file, all of the functions defined in the file are made available while the drawing remains open. Based on how you load or deploy an AutoLISP file, you might need to let the AutoCAD program know where your AutoLISP files are stored.

       Chapter 21 : Using the Visual LISP Editor (Windows only) In this chapter, you will learn how to use the Visual LISP® Editor. The editor provides tools for writing, formatting, validating, and debugging code in an AutoLISP file. Using the Visual LISP Editor, you can group AutoLISP files into project files, which make them easy to manage and compile. Compiling an AutoLISP file secures the source code contained in the file so that it can't be altered by others.
