First, specify a point on the screen, and then follow the prompts:
Specify the next vertex or [arc (a)/half width (h)/length (L)/discard (u)/width (w)]. You can set it as needed.
The "arc" specifies the width of the arc to draw any angle. The "half width" refers to the half width of the multiline, that is, if the width is 10, 5; the "length" gives the corresponding value, draw a multi-line with the corresponding length. "abandon" means giving up an operation. "width" refers to the width of the multi-line.

Multi-line (ML) multi-line editing (mledit)
Building diagrams are generally divided into two categories: construction drawing and interior decoration Diagram
Call a line chart: Right-click any floating toolbar-custom-command-drawing-multiline
Multi-line width control. The default width is 1. Because n times of 1 is N.
The number of lines on multiple lines can be changed: the format is that when the multi-line style is used to draw a building diagram, the multi-line is generally set to three.
Multi-line proportional control-for wall thickness. The general proportion is 120 240 360 480.
There is an alignment setting when drawing multi-line: There are three Alignment Methods: top, bottom, and none. Select "NONE" during the painting process ". Align the cursor with the center. And below are generally not used.
Multi-line trim is not allowed if it is not cracked. (Note: it cannot be restored after being cracked !)
After the architectural wall painting is completed, you can delete the middle line. Use: tool-quick selection-Color Selection
If no color is selected. There are two reasons. First, the color code is incorrect. Second, the multiline is not broken down.
The size of doors and windows in the building: windows are generally 1.5x1.2X0.12. The door generally has 0.04x0.9x2.0, and the Unit is meter)
There is also a painting of architectural Diagrams-if all your apartment sizes go to the house and use a ruler. First, draw the interior wall. Use the offset.
Layers: (mainly assigning objects)
Opening and Closing layers: all layers can be opened or closed. The layers are not displayed or drawn, but are calculated.
Freeze layers: The current layer cannot be frozen, and other layers can be frozen.
Lock of a layer: the locked layer cannot delete objects, but it can be used to draw images.
Images that are not modified can be changed as the layers are transferred.
Objects contained in layers cannot be deleted. To delete the content of a layer, you must delete it first.
The layer 0 cannot be deleted, and the definition point layer cannot be deleted. The current layer cannot be deleted.
Classification of layers:
Building: house type, furniture, annotation, and each room
Mechanical: dotted line, dot line, graphics, labeling
Generally, layer settings:
Drawing, text, dotted line, dotted line, frame, and Annotation
Note: loading a single line: the dotted line indicates invisible lines, the dotted line indicates symmetric lines, and the linear proportion adjustment.
Note: If you want to select all objects of a layer: Tools-quick selection-Layers
The title bar is 110 larger than 180.
The line spacing is 7 or 8 millimeters.
Title Bar content: design, drawing, review, approval, standardization, drawing name, proportion, Drawing Number, drawing, view, etc.
Use of some auxiliary functions in AutoCAD:
Query function:
Area calculation: if multiple lines are drawn, the boundary is used first. Then perform the calculation.
The first rule is the calculation of the graphic area: tool-query-area, and then find the area at a point and a point.
Calculation of the second irregular image area: tool-query-area and then input "O"
Calculation of area increase and decrease: calculate with the plus mode and then the minus mode.
Distance: only the distance of the Line Segment can be counted.
Calculation of the arc distance: view the arc length using the available features. Another type is "query"-"list display ".
Note: The handle is a code inside the computer. It is not the same.
Indicates the arc length. Generally, an arc is manually added to the dimension.
Mass calculation: the characteristics of the surface or mass, measured in MG. The default density is the water density.
CAL: Calculator
Coordinates of the vertex: (you can view the absolute coordinates based on the object characteristics)
Time: query the file opening time
Automatic disk storage: tool -- option -- open and save command: savetime
Use of the PE command (Open Path) to change to the overall format: Right-click the PE object and select J [closed path to overall]
Three methods: PE, area, and border
You can add a password in AutoCAD: Security Options, status, and many items are listed.
Fill (fill whether the system variables are displayed) can be input: On, off.

Super Link Ctrl + K application. Insert-hyperlink can be copied. When using a hyperlink, right-click the menu.
Annotation: scale is an important part of a plane image. [Annotation toolbar]
Line type annotation: finds the first vertex and then finds the second vertex by default. You can right-click a small box to facilitate labeling. The labeled data is the variable of X and the variable of Y.
Alignment: The Marked distance is the actual size.
Coordinate: Enable the orthogonal function before Marking coordinates. The coordinate value marked along the horizontal direction is the coordinate value of the Y axis (absolute coordinate value) the coordinate value marked along the vertical direction is the coordinate value of X (absolute coordinate value)
Note: The coordinate system origin can be freely changed.
Radius and diameter: used to mark the radius and smuggling of circles and arcs.
Arc: radius is the most commonly used. Circle: available radius and diameter. Casual.
Angle: The angle cannot be specified for an infinitely long line.
Baseline annotation: The baseline annotation can be used only when there is a annotation. The left vertex of the first annotation is based on the left vertex, And the right vertex of the first annotation is based on the right vertex.
Continuous labeling: there must also be a premise. Then one by one.
Lead: lead a line to facilitate dimensions that cannot be labeled. The movement of the text marked by the lead does not affect the lead. Press ESC after drawing the lead.
Tolerances: the number of tolerances can be provided based on actual experience or manual inspection. Tolerance: (shape and tolerance) (Note: The tolerance is described in detail. You can buy teaching materials by yourself.) The tolerances cannot be broken down. It is an external reference class. To modify the settings, edit the text.
Center mark: Add a mark to the center. The default size is 2.5mm.
Tilt: Tilt the annotation, and the selected Tilt Angle
Alignment text: five options are available: (default, angle, left, center, right)
Style: You can change the style of the annotation.
Annotation style:
The following buttons are displayed on the homepage of the "label style" dialog box:
Set to current: Set a label style to current.
New: Create a New Annotation style.
Modify: Modify the annotation style options. Change the labels in this graph directly
Alternative: replace some options in the current annotation style with other options. But do not change the marked object.

After entering the vertices, we will continue to set the new annotation style.
Click Modify and replace to enter the next level dialog box is the same:
Line and Arrow: This tab changes the property of the line and arrow marked.
Text: This tab is used to edit the annotation text attributes.
Adjustment: adjust some annotation settings. The focus is: global proportion
Main Unit: Set the unit and accuracy of the annotation. And the labeled proportional factor (note: the proportional factor cannot be changed at will .)
Conversion unit: If checked. The conversion unit of the annotation is displayed. (Before the metric mm and ft. inches)
Tolerances: Set the tolerances. Generally, this is not required.
Note: Label proportion control: global proportion control. If the image box is enlarged by N times, the global ratio is n times.
If the box on the contrary is reduced by 1/N, the global ratio is 1/N.
Tolerances: Pr formula:
Basic: Dimension \ H tolerance height \ s upper deviation ^ lower Deviation
Note: H and S must be capitalized.
Image: H can be set to between 1.25 and 1.5.
1: N: H is set to 1.25n-1.5N.
1: n. The global scale is set to n. On the contrary.
As long as the drawing is accurate, be sure to draw according to the actual size. The image box can be enlarged n times to enclose the image. The image proportion is 1: N.
Alternative: No application
Update: updates the annotation without application.
Update associated tags: Updates associated tags without application
The annotation line and text are a whole. To move the annotation text, you must break it down and move it.
You can also enter it in text.
If the text is stacked together after the annotation, you can blow it up and move it to adjust the position.
The multiplication numbers in mathematics can be replaced by uppercase "X.
Axis side chart
Three views:
The planes, facades, and sides are perpendicular to each other.
The front view is the main view. It can be the Left view only after the main view is determined. If there are many surface parameters, the plane is generally set as the main view, followed by other views.
The user-defined diagram usually uses a portrait plan.
Three view structure:
The main view and the top view are long-aligned
The master and left views are high.
The top view and the Left view are equal in width.
China Standard: place the Left view on the right and the right view on the left.
There are four types of graphics: (graphic description)
1. Normal Orthogonal View
Ii. Full-cut view
Iii. Semi-sectional view
Iv. Local profiling View
Two Methods of graphic expression:
First-angle painting
Triangle plot
Axis Map
Axis map definition:
1. Go to the axis ing System: Tools-sketch settings-capture and grid-select "Axis Test capture ".
2. Normally, the orthogonal mode is enabled, and the offset and image cannot be used directly during the axing process. The F5 key can be switched cyclically between the top, right, and left. The angle difference between the two sides is 120 degrees. The three sides are perpendicular to each other. During the painting process, the three sides must be constantly switched to form a three-dimensional plane.
3. Axis ing expresses the three-dimensional structure through a plane image. The circle in the axis ing system must be drawn by an elliptic plot. After an elliptical icon is clicked, enter I to determine the center of the circle, and then the radius to draw an equiaxial circle.
4. The center of the rounded corner must be determined when the circle is inverted, and the Axis side circle must be drawn to form an inverted circle by trimming.
5. axis ing annotation: for linear village injection, the "alignment" annotation is generally used, and then the "annotation" "--" Tilt "is applied. After the point is marked, according to the direction input, the formal negative 30 degrees, forming a labeling veneer, labeling of the circle and the inverted circle, must be self-made.
Axis ing direction:
Upper North, lower south, left West, and right East (view, Southwest view from 45 degrees ).
Tips for creating an axis chart:
Thread drawing:
Drawing an explosion chart:
Draw a regular polygon in the axis ing: Use the constant number of points to do it.
The inverted circle of the Axis map:
There are three kinds of AutoCAD inverted circle chamfering: plane, Axis Test, 3D
The chamfer of the Axis map is controlled by D, and can be inverted directly.
Inverted circle: you cannot reverse it directly. You must use an elliptical circle to draw an elliptical circle from the center of the circle and trim it.
Labeling method: After marking, mark the positive or negative tilt for 30 degrees. The labeling of the circle and the elliptic must be done using the lead.
Axis ing is a quasi-three-dimensional image, and a three-dimensional image is a quasi-axis ing image.
The first time a 3D graph is decomposed, it is divided by a body into a plane, and then by a plane into a line.
Accurate dimensional axis plotting
The tangent of a large circle and a small circle in the axis map. First, find the cut point, draw and extend it, and then draw another point in the connection.
3D part
3D notes:
UCs: user coordinate (coordinate) system (system)
WCS: Word (World) Coordinate (coordinate) system (system)
UCs type:
1. The origin UCS can place the origin of the coordinate system without changing the three axes of X, Y, and Z.
2. Z axis vector UCS: The first point is the origin, and the second point is the positive direction of the Z axis.
3.3 point UCOS: The first point is the origin, the second point is the positive direction of the X axis, and the third point is the positive direction of the Y axis.
4. x/y/z axis rotation. UCOS: From the origin point to the positive direction of the fixed axis, it is negative clockwise and positive clockwise. The rotation means that the two axes rotate the same angle to the third axis at the same time.
5. Face-to-face (UCS): Quickly place the X and Y planes on the selected plane. The reference plane can only be a plane, but not a plane.
6. Object: the object is used to rotate the X and Y axes in the X and Y planes;
The orientation of the XY axis changes without leaving the original surface. The point of the point is used as the positive direction of the X axis, and the endpoint closest to the point is the origin point.
7. view: regardless of the direction of the X, Y, and Z axes of the current UCs, the view UCS can place X in the horizontal direction, and Y in the vertical direction, in this way, the views of different files can be unified.
Note: In AutoCAD modeling, the important content is the constant switching of the view space and the flexible application of UCs, mainly the entity modeling, and the weak function of AutoCAD surface modeling.
3D menu operations:
View: (the following view is available under the View menu)
Six plane views: Top View, Back View, Left view, right view, main view (also known as front view), and back view
Four lateral view of the same axis: the lateral view of the Southwest, the lateral view of the Southeast, the lateral view of the Northeast, and the lateral view of the northwest. The four views view the image from the 45-degree diagonal line.
Camera view: determines a view based on two points; from the first point to the second point.
Entity toolbar:
Drawing of three basic systems (cuboid, sphere, and cylinder), cone, wedge, and ring
Stretch Modeling: (premise: it must be the closed body connected at the beginning and end) the default operation is to give a height to the stretch angle, the stretch angle is defined as: the positive value is getting smaller and smaller, and the negative value is getting bigger and bigger; stretch along the path: to draw perpendicular to the drawing and only on the X and Y surfaces. Example: Chair creation.
Rotation Modeling: three parameters are optional, but generally not required. Basic operation: determine an axis rotation at two points. Examples: bowl preparation and Round Table Creation
Split: The following prompt is displayed after selecting an object:
Specify the first point on the plane, according to [object (o)/Z axis (Z)/View (v)/XY plane (xy)/YZ plane (YZ) /ZX plane (ZX)/three points (3)]
"Object" is an object (circle, elliptical, arc, two-dimensional spline or two-dimensional multiline) to cut the actual body; "Z axis" is a plane Z axis (normal) "View" specifies three points on the object in the view to split the actual body. The "XY plane" uses the XY plane to split the actual body; the "YZ plane" uses the YZ plane to split the actual body. The "zx plane" uses the ZX plane to split the actual body; "Three points" specifies three points to determine a plane to split the actual body (three points form numerous faces on a straight line)
Cut: like the cut operation, the difference is that the cut will not split the entity, but form a plane at the split; equivalent to the cross section, only extract the cross section, rather than actually cut the object.
Interference: calculates two objects, which is equivalent to the intersection, so that the original object is not deleted.

3D image: The image is taken as a reference. By default, three images are used most.
3D array: An array with two options (rectangular array and circular array. A rectangular array can form a cube. The ring array rotates with one axis.
3D Rotation: Use two points to determine a axis for rotation. (Example: Chair creation .)
Alignment: one point alignment, which is equivalent to moving alignment. Two points alignment: Align the target object with the reference object with two points. You can choose whether to scale the object. Three points alignment: align the target object with the reference object at three points.
Rendering toolbar: (weak function) You can use the user chart to explain.
Rename: You can rename some objects.
Chapter 5: printing and advanced Customization
Print: print it in the model view. Print the new style table: file -- print -- New -- set in the dialog box.
Basic width of the printer: laser printer: Red Line: 0.2; white line: 0.4
Layout printing: the first option of the View menu: You can set it. The application of the toolbar of the view: the first option is the Cabinet-shaped view, the second option is the multi-side view, and the third option is to convert the object to the view port, the fourth option is the cropping of the view. To create a new view, delete the content first. You can also create a layout;
Set the image unit: format-Unit
The benchmark direction is east.
Thickness: format-thickness, generally not used; graphic boundaries: the size of the drawing can be set
Button Function in the status bar:
Capture: it is determined by the grid.
Grid: you can set a grid point. It is useful for capturing and searching. Not Required
Orthogonal: when open, generally only horizontal and vertical lines can be drawn.
Polar Axis: You can set the angle.
Object capturing: used to capture special points. It is widely used.
Object tracing: displays tracing from a specific angle.
Width setting: it is not a desirable method. Color is used to distinguish Graphs without line width.
Import MAX: file-import in Max. Select the file type of DWG.
Search and replace: Edit -- search
External Reference: insert-External Reference (large companies use more, suitable for overall control)
Use of OLE objects:
Grating image: image transfer and Modification
AutoCAD installation directory \ sample \ designcenter \: Use of the Design Center
Point filtering, which is equivalent to extracting X, that is, filtering x
Backup File Usage: Change the extension to. DWG
Tool-Option-open and save-security option can encrypt and save the file to 2004 format to have a password
Expand a chart: expand a chart.
Draw the Intersection Line: a line segment shared by two Geometries
Drawing a perspective: the relationship between parallel lines -- divergent projection -- intersection with a point, you can draw a perspective.
Production of shortcuts:
Format: A shortcut key can contain letters, numbers, or a combination of the two. * is the full name of an English command.
For example:
1, * lime: Indicates entering "1" to draw a straight line
2, * circle indicates entering "2" to draw circles
SJ, * mline indicates that SJ can draw multiple lines
Input the preceding content: tool menu-custom-edit user-defined file-program parameters. Add control operation text in the preceding format to this file. After setting, close AutoCAD, it works when you re-open the program.
File Size: For the same image, the version 2004 can be reduced by 2002 compared with the version 30%.
