[Explanation process]

I. layers:

1. Create a layer: Set the name, color, and line type of the layer (the line type must be loaded)

2. layer properties: open/close; freeze/Unfreeze; lock/unlock remarks: the current layer cannot be frozen, nor can it be set to the current layer.

2. Draw the center line on the center line Layer

1. Set the central line layer to the current layer first: the color and line type are set to the default with layer.

2. Start to draw the horizontal and vertical center line (axis ). Note: We recommend that you enable orthogonal mode.

3. Use the offset or Copy command to draw multiple centers.

4. Use the stretching command to uniformly lengthen or shorten the length of the center line. Alternatively, you can use the clip point editing method to lengthen or shorten a cable separately (note that automatic capturing is disabled and then enabled ).

3. Start to draw basic entities on layer 0 or other layers

1. Set layer 0 or other layers to the current layer.

2. Use a straight line, an arc, or a circle

3. After selecting an object, change the layer.

4. Use copying, moving, deleting, mirroring, and offset to process objects

5. accurately draw objects: You must use various object capturing methods to accurately capture points (Note: Object capturing methods and sequences ). The key is interaction with commands!

Set and draw multi-line styles

1. You need to set a multiline style.

1. multiline format

2. Cable proportion: 2.4 is recommended (240 of wall)

3. Positive Direction: zero offset

4,

5. Remarks: the width of a multi-line model = the unit width of a multi-line model × the multi-line Proportional Factor

2. Draw multiple lines

1. Run the multiline command: mline or use the toolbar button

2. Suggestion: Draw segments (horizontal and vertical areas should be drawn separately as much as possible)

3. Multi-line editing

1. multiline Merge (Corner close, cross open, etc)

2. Multi-line interruption

I. Advanced plotting,

1. scoring criteria:

2. Score ratio:

3. assessment requirements:

Ii. entity plotting

3. precise plotting

1. Auxiliary drawing tools:

(1) Ortho: orthogonal method;

(2) grid;

(3) fill filling mode;

(4) quick text: quick text display

(5) (*) Capture geometric points on an object [preset capturing, using point filtering (. X. YZ) for example: (200,180, 50) ()]

(6) display control: Zoom (screen zoom) (A: All, E: display the entire image as big as possible); Pan (view); view (View Management ); viewres (view resolution); redraw (redraw) regen (regenerate)

(7) Transparent command: Enter '(single quotation marks) and transparent command when running the drawing command. Features: After a transparent command is executed, no entity object is generated, the object is deleted, or the object is modified. Commonly used: Zoom, pan, redraw; query command (Dist, ID, time, status)

2. Drawing Query

(1) Dist specifies the first point: Specifies the second point: distance, the angle in the XY plane, and the angle between the XY plane; X increment, y increment, and Z increment (except distance, other measurements are related to the order of points)

(2) Area: Specify the first corner or [object (o)/Add (a)/subtract (s)] remarks: O is the object; A: Add; s: Subtract reduced

(3) List: lists all internal properties of the selected object.

(4) ID: vertex attributes (x, y, z)

(5) Time: displays the current date and time

(6) Status: displays various entity states of the current graph.

(7) dblist: Data list of each object in the current Graph

3. Other functions of Display Control: View (window-multiple windows can be generated), view (a graphical window can be defined as a graphical window that exists as a graphic at the same time, only in the same window)

5 ,...

Note: All alias information is in one file: Support \ Acad. PGP (PGP: Program prompt)

3. graphic editing

1. Create a selection set

(1) Select set options:

Click mode, window mode: w (window dragged from left to right); crossing mode: C (window dragged from right to left); last: l the last visible object created; box: automatically identifies rectangular boxes; All: all objects; fence: F fence mode; wpolygon: Window polygon; cpolygon: Cross polygon; remove: Remove from select set; Add: Add select set; multiple: Multi-Point mode; previous: select the previous set; UNDO; Auto:; single: Select once

(2) construct the select set command: select

(3) construct an object group

2. Edit commands

(1) Deletion and restoration of objects: erase; oops (restoration and deletion); U, undo, redo

(2) Copying objects: Copy (M: multiple copies); offset (offset command); mirror (image command); Array (array command) (R: rectangular array; p: Ring array)

(3) change the object location and size: Move (MOVE); rotate (rotate) (R: reference, difference between two specified angles; rotate the specified angle to another specified angle ); scale (scale) (s scale factor, R: reference); align (Pan rotation; move, rotate and scale );

(4) Changing the shape and characteristics of an object: Stretch (stretch command), trim (TRIM command), extend (extension command), and fillet (inverted rounded corner command) (default: select the target rounded corner; select second object: P: round corner of the Multi-definition line; R: Set the round radius; T: Set the trim status); chamfer (chamfer command; P: for multi-definition line chamfering, D: two-side inverted angle distance, A: One chamfer distance and the angle of the chamfer, T: Set the trim state, M: The chamfer method (distance angle), and the other: can connect two non-intersecting lines); break (disconnect command; F: reselect the first point; @: cut at the same point); pedit (edit the multi-definition line: Default: exit; C: closed; J: connection; W: linewidth; E: vertex editing; F: curve fitting; s: B-spline; D: straightening curve (F, S); L: Linear ); splinedit (spline editing command: F: Edit feature points; C: closed; M: feature point movement );

(5) Editing by clamping point: five modes of editing by clamping point: stretch; move; rotate; scale; mirror

Cooperation: "base point" and "copy" options.

Note:

(1) fillet

Current Mode: mode = trim, radius = 10.0000

Select the first object or [multiline (P)/radius (r)/trim (t)]:

(Command: _ fillet

Current Mode: mode = trim, radius = 10.0000

Select the first object or [multiline (P)/radius (r)/trim (t)]: T

Enter the trim mode option [trim (T)/not trim (n)]: N

Select the first object or [multiline (P)/radius (r)/trim (t)])

(2) _ break selection object:

Specify the second breakpoint or [first point (f)]: F

Specify the first breakpoint: _ mid on

Specify the second breakpoint :@

3.

Iv. Additional layers

1. With layer/with block color and line type: bylayer, byblock

2. Dominant Color and line type: the entity drawn using the dominant color and line type does not change with the color and Dominant Color of the layer where the entity is located.

3. Define the point layer (defpoint): it is generated with the generation of dimension labels. We recommend that you do not draw images on this layer.

4. Copying different layer entities: the Copied object remains the color and line of the original layer;

5. Inverted rounded corner/inverted line between different straight lines

6. Inverted rounded corner/inverted line between different multilines: two different multilines will be merged into one, and the second selected will be merged by the first selected multiline.

7. Inverted rounded corner/inverted line between a straight line and a multi-line: the line will be merged by the multi-line

V. Graph Blocks

1. Create a graph block: block [B] (Create an internal block); wblock [w] (Create an external block)

(1) The initial graph must be drawn on layer 0.

Step: [1] draw a graph [2] Run the draw Command [3]: Name-> base point-> select an object->

After creating a block, if you choose to delete an object, you can use oops to restore it!

(2) Insert a graph block: insert

(3) Write external blocks: wblock command, alias W

(4) Several settings for inserting an external block: insertion base point, overall proportion, X or Y ratio, rotation angle, etc;

2. Use the block and attribute together

(1) attribute definition: four modes (invisible, fixed, verified, and preset)

(2) define the map block together with the image:

(3) Insert an attribute block:

(4) Modify an attribute block:

In acad2000, perform the following operations: [modify-> attribute --> single]: it is mainly used to modify the attribute value or [modify-> attribute --> Global]: it is mainly used to set all attributes (including values, positions, rotation angles, and so on)

Operation in ACAD R14: [modify-> Object-> attribute --> single]: Mainly used to modify the attribute value or [modify-> Object-> attribute --> Global]: it is mainly used to set all attributes (including values, positions, rotation angles, and so on)

3. Graph block array

Command: minsert. The difference between minsert and array is that the object after the command array is a whole and cannot be decomposed.

= 1 = simulated demonstration of the test environment =

1. Intermediate Test Environment Demonstration:

Note:

(1) paper: the Intermediate Examination is divided into two documents: the theoretical part is handed in first, and then enter AutoCAD R14 to enter the drawing part, and finally the application part is handed in. In addition, the theoretical part cannot be returned to the theoretical part after being handed in.

(2) Tips: when taking the theoretical part of the Intermediate Examination, you can open the AutoCAD R14 program through the Start Menu, then switch between the examination interface and AutoCAD R14 (use (Alt + TAB or Alt + ESC) to help complete the theoretical part of the answer.

(3) Secondary exam students must note that they must be saved to the specified directory: C: \ zccad. When submitting some documents, they must first close AutoCAD R14, then you can hand in the paper. Otherwise, a transfer error occurs. The test time is 150 minutes, that is, 2 hours and 30 minutes.

2. Demonstration of the advanced examination environment:

(1) Submit: the advanced exam only has one assignment, and you can switch between theoretical and graphic questions.

(2) Tips: Students of the advanced examination can switch between Operation questions and theoretical questions throughout the examination. This can help answer questions in the theoretical part.

(3) students of the advanced examination should note that they should also be saved during plotting. The examination time is 90 minutes, that is, 1 hour and 30 minutes.
