Explode 分解

Convert a polyline into its most basic shapes such as lines and arcs

Explode a polyline, all the attributes associated with polylines, such as width, are lost and a separate object is created for each segment

Polyline 多段线

Polylines are special types of entities that incorporate segments such as lines and arcs into a single object

Use polylines can easily calculate a perimeter distance or the area of an irregular shape

Sharp corners are maintained in the offset

Polylines also have special properties:

■ Global Width

■ Start Segment Width

■ End Segment Width

Create Polyline

Create line and arc segments as a continuous single object

Pline - Arc - Line - Width (start, end width)

Polyline Edit 编辑多段线

Change certain characteristics of a polyline

Double-click on polyline to edit mode

Open

Convert a line or arc into a polyline

Tool Palettes 工具窗口

Organize and access the tools you use most often

Tool Palettes window contains a tab for each tool palette

Add tools to Palette

2 ways:

■ Drag blocks or drawing files from DesignCenter

■ Right-click and drag a single piece of geometry from the drawing to a palette

Insert objects from Tool Palette

Click an object and insert into the drawing

DesignCenter 设计中心

Reuse data from another drawing in the active drawing

Saves design time and helps ensure consistency across designs and among designers

 Tree View

 Preview

 Description

Tree View, Preview, Description can be turn off

Insert blocks from DesignCenter

2 ways:

1. Drag the block from DesignCenter into the drawing

2. Double-click on the block

Can set the Scale, Rotation angle

Insert Block 插入图块

Insert blocks from drawing database or any location in the hard disk

1. Specify the name of a block to insert

2. Select a drawing file to insert as a block

3. Preview of the selected block

4. Specify the insertion point on-screen

5. X, Y scaling factors

    Different X, Y scale, the block will scaled proportionately 

6. Specify the rotation angle of the block

Insert a drawing file, the drawing geometry references will come with it

Create Blocks 创建图块

Creates a single object out of multiple objects so they appear and behave like a single piece of geometry

Block Definition: Block stored in the drawing database

Block Reference: A visible block definition in a drawing

1. Name: Specify the Block name

2. Base point: Click the button to define the Base point (insert point)

    It's important to specify the base point for the block, otherwise the base point will be 0,0,0

3. Select the options

    Retain: left as individual objects

    Create a similar block     

    Convert to block

    Using now

    Delete

    Pre-create all blocks, use later

4. Behavior

     Annotative: Display same size in the different viewport scale

     Scale uniformly: Same scale on both X, Y axis

     Allow exploding

5. Description

6. Select objects

Block 图块

A collection of objects grouped together into a single object

A object form by individual lines, arcs, and polylines, and repeating use in same drawing or other drawing, it's good to convert it to block
