What is a CAD chunking command? The answer I want is not to define the block command b,

First, the command technology:

QLEADER[le]: arrow with text.

Cross the circle

Ded: the purpose of modifying the marker line /gove[o]/ Select the modified marker/Select slash/Confirm.

Len hen[len]: Increase or shorten the/number of the object/(positive number means increase, negative number means shorten).

Ltscale: set the line scale.

Div: bisect the line segment (the normal form of the point should be selected before bisecting)

Section [I]: obey the command of division, and div is division.

Example: Apply the command of me or Div, then select a path (such as a line) and enter the name of the block just defined, then enter the equal distance or equal fraction, and then confirm.

Hatch: You can populate objects with commands.

H: You can fill in objects with dialog boxes.

He: Edit the filling mode of civil industry.

Snap: Switch to the inside of the axonometric model /S/I/ Confirm (F5 can be used to switch faces).

Regions: regions/selected objects (closed drawings)

Mvlew[mv]: You can create a new viewport with irregular boundaries by converting objects drawn in paper space into viewports (this command is used for paper structures).

Constraints: Set graphic boundaries.

Donuts [do]: Fill circles and create rings.

Draworder[dr]: Change the instructions of images and other objects in turn.

AV: open the aerial view.

So: Set a solid filled polygon.

Splinedit: editing spline curves

Stretch[st]: Stretch (note: when selecting objects, write a block command in cad to select from right to left and move when selecting all).

To: customize the east-west bar

W: Write the object to a new graphic file.

Filter [fi]: object selection water curtain.

Remove [pu]: Remove debris.

Insert [i]: Insert and check the block name.

Tilemode: transformation between model and structure (1 is model and 0 is structure)

Oops: Sometimes, after deleting some primitives, many operations are reversed, but the primitives that need to be deleted are found. If you quit at this time, the following operations will be done in vain, and it will be troublesome to redraw the deleted primitives. At this point, you can use the OOPS command to restore the deleted primitive. Note that OOPS can only restore the last deleted primitive.

Second, the selection skills.

When selecting elements, you can also use process help to help you select them:

Previous [p]: Select the entity of the previous operation.

Remove[r]: Deletes the selected entity (usually used when using the stretch command).

Add [a]: Add the selected entity (after applying deletion).

When you click the box with the mouse to select a graphic element, the selected graphic element is highlighted, and then the keyboard inputs an edit command to edit, which can trick Hello FT Jian into deleting the graphic element selected by the parallel branch.

There is really another point, which may be more straightforward: after selecting an object, I found that some lines were not selected. At this time, press and hold the "S Hello ft" key, and you can edit the block command for reverse selection.

When using the "Cut" or "Extend" command, you don't select the object, just press the space, so you can cut or extend freely without restriction.

3. Input special numbering technology

%%P

%%C:

%%D 0

\U+00b3 m3

\U+00b2 m2

(Note: This is 0 to 0, which can only be predicted in the imitation, and the rest fonts are not good. )

In addition, the upper and lower corner markers in CAD: MTEXT command are applied; Mark the upper corner as ㎡ and mark it as m2. Select 2 and click the A/B key. The lower corner is written as m 2. Select 2 and click the key a/b. ..

4. Other technologies

First, the benefits of cheating external dynamic blocks in CAD.

In the communication of foreign landscape and interior design companies, they have a very good drawing habit, that is, they accept the form of reference, that is, insert/external reference/public building basemap, and then draw in the page space when drawing, which is more convenient than forcing, so that once the building changes, the reference will automatically start again at any time, thus stopping the invalid action and improving the efficiency of things. At the same time, it is more convenient to draw pictures and make the same demarcation than to use force.

Secondly, the foreign essentials are correct, and the author also provides a kind of essentials for reference: sharing the base map, accepting the parameters of the external cad blasting headquarters, drawing in the model space as usual, locking the shared base map, and then using the LMAN command to control the drawing and lay out the layers.

Key points for modifying blocks and xrefs:

Directly click or double-click the block and external reference to be modified, and then click OK to enter the reference editing standard style. In this block, you can arbitrarily modify the properties of the elements in the block or edit the elements. Click Save Modification of Reference in Reference Edit after modification, or click Abandon Modification of Reference if it is not necessary to save modification. Click OK to return to the drawing model.

It should be noted that if the diagram with external parameters is modified in this diagram, the external reference diagram, that is, the base map, will also be modified accordingly. Therefore, the external parameter diagram should be carefully modified.

Change the backup file to a CAD document

After modifying the CAD drawing, a BAK file (backup file) will be automatically generated. How to restore its backup files? Under the window, things/folder options/view/uncheck the extended name of the hidden known file type, set the extended name of the file, and then change BAK to DWG.

Set a scaled border in the structure.

Draw a drawing frame according to the actual size of the structure, adjust the cad explosive block command to the east-west column of the viewport, enter the MVIEW[MV] command to create a new viewport and adjust its size, double-click the new viewport, step into the model, and select the drawing scale in the east-west column of the viewport.

If the colors in CAD drawings overlap, the colors will be confused after converting the pictures. You can choose to block two objects and then convert them into pictures, so that light colors will not be covered by dark colors.

Opening a CAD document directly sometimes leads to block explosion or other similar problems. First, open CAD, then open the drawing from CAD, use the AUDIT repair command, and then apply the explosion command.

The patterns of the two open poses are different, and some of them will change slightly.

Essentials of calculating arc length by CAD: (This essentials can be used to calculate the parameters of two-dimensional graphics and straight lines and the dimensions of plane or object surface)

1. As long as the arc to be measured is drawn directly, use lenhen[Len] to lengthen the life command and directly select the arc length.

2.LIST[LI] can be used to obtain all parameters of an arc, including center, radius, starting angle, ending angle, etc.

3. After executing the "area" command, select the object option, and select the calculated figure according to the prompt, and AutoCAD will automatically calculate the size and perimeter of the plane or surface of the object.

4. For complex closed graphics composed of simple lines and arcs, the area command cannot be directly executed to calculate the size of the graphic plane or the surface of the object. You must first write a block command, apply the region command to create an AREA, then execute the command area, then input the object, and finally select the object.

Blocks inserted by the MINSERT command cannot be decomposed. You can use MINSERT to copy 2 copies and delete the original graphic elements. It is a read-only file, but you'd better save one first! MINSERT copy 1 copy can be modified by blasting.

Sometimes, plans copied from other places will make fatal mistakes on the way to revision, and then automatically quit. How to solve it? It should be the original picture, which can be remedied by clearing (liquidation) and auditing (maintenance) orders.

This is the addition function of CAD2000 initiated by ourselves. Through this process, it can get a selection set of institutions according to the premise. After the QSELECT command is entered, the "Quick Selection" dialog box pops up, and you can choose according to the type of the specified object, the characteristics of the specified object to be drenched, the drenching range, etc. You can also press the right mouse button in the drawing window of your active CAD2000, and the menu contains the "quick selection" option. However, it should be noted that this function is not applicable if the selected object feature we set is "with layers".

Selection of formation formation

Combine several objects. When prompted to "select object:", type g (group) and press enter, and then the command line displays "Enter group name:". Enter the group name at the prompt of the block write command and press Enter, and the corresponding graph will be selected. This posture mode is suitable for those objects that need frequent operations. In addition, if an object is directly selected at the prompt of "Select Object:", all objects in the group to which the object belongs will be selected.

Combining the "block" and attribute function of AutoCAD 2000 skillfully can greatly improve the drawing efficiency. "Blocks" can be divided into internal blocks and external blocks.

An internal block is a block defined in a file and can be used freely in the file. Once the internal block is defined, it will be stored and opened simultaneously.

The external block writes the main file of the "block" to disk, and other graphics files can also apply it. It should be noted that this is an important difference between external tiles and internal tiles.

Clever use of space:

Select the base point of the pattern: (that is, when selecting an object, a blue dot appears, and then select a blue dot with red as the base point)

The following spaces: Move command;

The second space: rotation command;

Three spaces: zoom command;

Four spaces: mirror order.

Shift Magic Effect: Fixed instrument offset capture or rotation capture.

Example: Draw a circle, left-click the bare-metal grab handle, and right-click the bare-metal command control block. Select Copy in the pop-up shortcut menu, drag the mouse for a certain distance, and left click to determine the position of the first circle to be copied. Now press the SHIFT key and drag the mouse on the screen again to expose the second circle.

Look! It is copied at equal distances, that is, small-scale arrays!

You can also rotate the array: draw a circle, grab the grip, click the space twice, adjust the rotation of the command line, enter the copy command c, enter the rotation angle of 30, and confirm the command with the space. At this time, hold down the SHIFT key, rotate the mouse in turn, and confirm the response position with bare metal, and the effect will come out!

SHIFT key, at the same time, you can quickly switch between pruning and expansion order. After entering the order, when you choose to abstract pruning or extend the money to the point, press SHIFT to switch the order.

It's really easier to copy with lines.

Draw a dollar first, select it, and expose the middle point (that is, a red dot appears). At this time, hold down the SHIFT key, drag a certain distance on the screen, and then expose the next one. You will find that this time is the same distance copy. If you release the SHIFT key, you can copy the object repeatedly.

Control of layers in viewports

If you only need to cut the cad block in the current viewport so as not to print a certain layer, for example, if you don't print the dimension layer in the current viewport, set the essentials in detail, double-click the current viewport to step into the model space in the drawing space (otherwise you can't control the layer in the current viewport), open the layer property handler, select the layer to be frozen in a single front viewport, and click Freeze in the current viewport.

Three-dimensional blanking printing function

Select the viewport (bare-metal viewport line) to be printed with blanking, and open the feature handler with an option of "Blanking and Printing". Select Yes to blank and draw.

Decompose text in AutoCAD2004! (Note: Song Ti can't be exploded, only line body can be exploded. )

1.wmf mode file-output-survival

2. After the point survives, prompt to select the object, select the text to be blasted, and press enter.

3. Click Insert -Windows Metafile-Select the existing file and insert it according to the prompt! ! !

All right! So the text became a line! ! !

Glue the graphics in CAD to Word;

1. Adjust the required graphics to full screen in cad, and then click File → Export to export the selected graphics as wmf pattern pictures.

2. In WORD, click Insert → Picture → From File, and select the previously exported wmf picture → Insert.

3. Right-click on the command list of the drawing cad editing block → Set the picture pattern → Layout → Floating above the text → OK.

4. Right-click the picture again → combine → ungroup, blow up the picture → click ESC.

5. Select the blasted picture scene → click the Delete key to delete the picture scene, leaving only the picture lines you want.

6. Select the picture lines to be bold (1, multiple or all lines), right-click the picture lines → set the patterns of optional graphics → colors and lines, select black as the color, and select the thickness as needed → OK.

7. At this time, each drawing line is separate and independent. Improper operation may cause one or several of them to shift and crush the integrity of the drawings. The solution is: select all lines, right-click lines → merge → merge, so that all lines will be merged into a complete and inseparable figure. This process is completely reversible and you can modify it at any time.

Using this method, you can ensure the pure vectorization operation of graphics, which looks a bit complicated, and you can easily complete any complicated graphics operation after mastering it.

How to replace the original font that can't be found in CAD: (This font can be replaced by Song Ti)

Select the font file to be replaced by abstract (such as hztxt.shx) and change it to the font name to be replaced by cad block order. For example:

Open a CAD file, prompting that the font hzst can't be found and you want to replace it with hztxt.shx, then you can go to the AutoCAD fonts folder, copy hztxt.shx in it, name it hzst.shx from the beginning, then put hzst.shx in the fonts folder, and then open the drawing from the beginning. In the future, if you open a file that contains fonts (such as hzst) that are not available on your pc, you will not be required to constantly replace them.

Draw the required boxes in advance, and then save the file (change the file type to graphic template file *. DWT)。 Copy this file to the original file disk \ program files \ AutoCAD 2004 \ template.

This way, every time you open cad, you can click New File, and then select the dwt file you copied earlier. (Anyone who will acquiesce after that)

Select a layer to freeze, open or close.

Los Angeles, okay

F↓ ok

~ * * OK (with symbol "~")

This can freeze all layers except "* *", and you can choose not to freeze the lower layers.

Measures to keep orthography of mirror fonts;

Type mirrtext at the command prompt, press enter, then enter 0, and then press enter.

Create a quick trick:

First, select the object to be created, then hold down the Ctrl+S Hello ft+C key at the same time, click the midpoint of the selected object with the mouse, and then hold down the Ctrl+S Hello ft+V key at the same time, and click the vacancy with the mouse. At this time, you can see that the glued object is already a whole piece.

Make a tangent circle quickly.

In plane cad, the adjacent relationship between one graphic element and another graphic element is tangent. When I first started learning AutoCAD software, I always used the method of radius addition or radius subtraction to draw tangent circles. It's really silly to think about it at this time. In fact, when we use the command of drawing a circle, we use the parameter "Ttr" to designate it as a tangent circle, then select the tangent objects A and B respectively, and then enter the radius of the transition circle, so we can easily make a tangent circle.

Double-click the wheel to maximize the chart.

Q: What preparations do you need to make to start painting?

A: Sharpening the knife does not mistake the woodcutter. Computer drawing, like manual drawing, also needs to make some necessary preparations. Such as setting layers, linetypes, labeling paradigms, strategy capture, cell mode, graphic boundaries, etc. Many repetitive things can be completed in advance in the model board drawings, such as ACAD. DWT, and can be used when drawing a new drawing.

How to mark words with scores?

1) Type the "mtext" command.

2) Positioning the boundary

3) Enter "1/2" in the pop-up box.

4) Type a space, and the space will be automatically superimposed and converted into a degree score in the pop-up box.

5) Confirm and confirm the order of cad editing blocks.

If you don't want to indicate a layer in the structure viewport:

Double-click inside the structure to activate one of the viewports.

Call the layer property handler to predict the details, select the layer you don't want to predict, and check the current layer freeze.
