Change" Function Description

Drawing tool The most used tool for drawing straight line L F is also very simple in usage. Because the commands such as straight line are used most frequently, but the key operation is very inconvenient, it is necessary for us to change it.

construction line XL—a straight line extending infinitely, which plays an auxiliary role in drawing such as labeling. Although it can be printed, it is not used as the drawing subject.

polyline PL—it is very useful. When filling, use this tool to create the boundary first, which can avoid the time for the machine to analyze the filling area. It is also very useful to calculate the area and perimeter. You can also use it to draw arrows and thick lines.

regular polygon pol-it is seldom used in drawing. Property is closed, you can set the global width, and you can query the area and perimeter of the created polygon with the feature tool.

Rectangular rec-a common tool, with closed properties, global width can be set, and the area and perimeter of the created polygon can be queried with the feature tool.

ARC—There are many ways to draw an arc, and the default is the first "three-point" circle drawing method in the menu.

circle cc is a common tool, the attribute is closed, and the global width can be set, and the area and perimeter of the created polygon can be queried with the feature tool. (it was changed to CC to reserve c for the copy command)

revision of cloud line rev cloud-used for emphasizing regional division and other purposes, which is generally not often used.

spline curve SPL—used to create curves with irregular shapes.

ellipse EL—used to create an ellipse.

ellipse arc EL-a—used to create ellipse arc.

insert block I—when inserting a block, the blocks in this file are displayed in the browse bar of the dialog box. If there are many unused blocks, you can clear them by executing the PU clear command, and then they will not be displayed.

create block b or w-b is used to create a block in this file, and w is used to create an external block file. After the creation of CAD26, the block can be edited directly by double-clicking. The operation space of the block editor is the same as the model space, but the default is to talk about the yellow background color, which can be modified into the customary color through options.

point PO—used for filling and bisecting lines, etc. If you can't see the command, you can execute the point style under the format menu to increase the percentage of point size.

hatch h-hatch command gives most legend patterns in architecture, but in fact, with the improvement of drawing aesthetics, more legends are needed, and other legends can be downloaded to supplement them. For the filling of some complex areas, it is best to use PL line or BO command to create the boundary first and then select the boundary to fill it, which will save the time for the machine to analyze the boundary of the filling area. If there is text in the filling area, you can select the text together with the border, so that the text will not be filled, and a gap will be left around the text. CAD26 supports the function of filling and trimming.

gradient GD—The gradient command is rarely used in two-dimensional drawing, while most of the three-dimensional drawing uses software such as 3Dmax, so this command is basically abandoned.

region reg-is a closed region with physical properties, which is mostly used for three-dimensional operation, and in two dimensions, it is used to calculate the area.

table TB-this function is not very convenient to operate, so it is suggested to edit the table with Eecel first, then copy it, and then paste the CAD editing menu selectively, and select CAD primitives to realize table conversion.

multi-line text mt-multi-line text is used to edit more text, and the current 26 edition has modeled many styles of Word, which is much more convenient to operate.

modify tool to Delete e-except for the e command, the delete key performs deletion.

COpy co or CP C because the copy command is widely used, it is suggested that the shortcut key be changed to C. By default, the 26 version of the copy command can be copied continuously, which is a great innovation of the copy command.

MI RRor mirr mirror if the original object needs to be deleted, it can be deleted directly in the mirror command, without another delete command.

offset O Q offset can use the division function, and CAD does not support addition, subtraction and multiplication. For example, if two lines with equal distance are offset between two 1-wide vertical lines, we can perform the offset, input 1/3, and then pick up the original line to offset twice, and now two lines with a distance of 33.3333 are generated. To offset the irregular polygon, it is required that the polygon is a closed

array AR-it is suitable for copying the graphics with more complex shapes, and the graphics that can be simply copied by the copy command should be copied as much as possible.

because the move command is used more, the original shortcut key m is not convenient to operate, so it is suggested to change it to the V key on the left hand side or other keys on the left hand side.

rotate RO R in some cases, we need to copy and rotate an object, and we can execute the rotation command, and then select copy c according to the prompt in the command bar. Because the rotation command is used more, the original shortcut key RO is not convenient to operate, so it is suggested to change it to a separate R key or other keys on the left hand side.

scale sc-you can use the division function in the command bar when scaling, and CAD does not support addition, subtraction and multiplication. For example, if you shrink an 8.25-wide primitive to 5-wide, you can enter SC in the command bar, and then enter 5/8.25. Now measure the width, and it is 5-wide. If you want to enlarge it by 1, it is 1/8.25, so you can zoom any width to the desired width.

stretch s-flexible use of stretch command can greatly improve the drawing efficiency. Any graphic object except blocks, groups and external references can be stretched in front, back, left, right and local of the graphic object if it is long or short, and this command can also be understood as moving the local position.

Trim TR—You can quickly cut objects by using F to delete columns when executing the trimming command. In the 26 version, the trimming command enhanced the trimming function, and you can select the parts to be deleted by using the picking box, and you can delete objects at one time. Unlike the previous version of 24, you need to click Delete one by one, which is much more convenient.

extend ex-if the reference edge to which it extends is not that long, it can be set to extend to the edge in the command bar, and it will still be valid after one setting.

break-execute this command to break the line and connect the two points formed by the break.

break at point br-execute this command to break the line, but the two points are separated after the break.

merge join—used to merge two adjacent lines in a straight line direction. Is the opposite of the interrupted command.

inverted right angle cha-you can invert a right angle with different lengths on both sides of the source.

trimming line segments by chamfering F FT is faster than cutting command in some cases. Just set the chamfering value to zero, and both chamfering and chamfering can be used. It is recommended to use round chamfering, because chamfering is used more in practical application.

decompose X—When decomposing a block, if it contains another block, you need to execute this command several times.

dimensioning tool linearly dimensioning DLI—A linear dimension is required between baseline dimensioning and continuous dimensioning.

alignment mark DAL DA alignment mark can mark horizontal and vertical lines, and can also mark diagonal lines, so it is suggested to use this mark by shortcut, but the disadvantage is that dragging one end of the mark point will rotate.

arc length labeling Dar-label the length of the arc.

coordinate marking dimord-mark the coordinates of the point.

radius dimension DRA—dimension the radius of a circle or arc.

bend marking jog-some arcs are only a short section and have a large foxiness. If the dimension line of the radius is displayed completely, it will be ugly, so you should use bend marking.

diameter dimension DDI—dimension the diameter of a circle or arc.

angle marking Dan-mark the included angle between two lines.

Quick dimensioning QDIM—Selecting dimensioning points can generate dimensioning between these points at one time, which is very quick and highly used.

baseline labeling DBA—When using baseline labeling, you need to create a linear labeling first.

continuous dimension DCO—When using continuous dimension, you need to create a linear dimension first.

fast leader LE—qleaper (LE) straight leader, leader (curve leader can be created).

TOL—it is rarely used in general, but some companies use it as a material identifier. I think this is a good method, which is more flexible and simple than the block method.

center mark DCE—used to mark the center point, which is displayed as a cross. You can change the size of the cross center mark through the marking style.

edit dimension DED—used to change dimension text or rotate dimension text and extension lines.

edit dimension text dimtedit—mainly used to change the alignment position of dimension text.

label update apply—use label update to update labels quickly, which is similar to format brush, but only the labels can be refreshed.

label style D—the most frequently used label style may be the setting of Arabic numeral size, and generally, 1, 5, 3 and other styles are established to represent the corresponding proportional characters.

other tools, single-line text dt-the editing function of single-line text is very simple, and it can only handle short text, but it is also very simple to use. However, when we draw, the marked text is very short, so we often use it.

zoom z-with the enhancement of mouse zoom function by CAD, the z command has lost its former elegance, but many people still use it to zoom in real time.

multi-line ML—used to draw walls, etc., and can draw multiple straight lines at one time. By default, there are only two lines, and the interval between these two lines can be set at will, generally 24mm and 12mm wall thickness.

calculator QC-(ctrl+8) starts the calculator program built in CAD to calculate various types of data.

circle DO—it is rarely used, and it is also offset by a circle, so you can ignore this command.

object capture setting ds-object capture is the specialty of CAD. Without it, CAD will be disabled. In the 26 version of CAD, the function of dynamic input has been added, that is, some commands and data under the command bar run to the cursor, but some people think it is an eyesore, so you can set it off here.

option op-almost every large-scale software has a similar function, which is equivalent to windows to the control panel.

forced alignment al-the main purpose is to align a graph with any angle to the desired position. It is a good complement to the rotation command, and accurate alignment can be completed without input angle.

create layout viewport mv-create a new viewport in the layout space, which is a rectangular viewport by default. Of course, you can also create a polygonal viewport according to the prompt of the command bar, or you can create an existing irregular closed graph as a viewport.

create a closed boundary bo-with this tool, a closed boundary can be created quickly and accurately. The main function of creating a boundary is to calculate the area, perimeter and filling pattern.

undo previous deletion oops-undo previous deletion. Note that it's only a step to undo. This command is very useful before creating boundaries, because some graphics are very miscellaneous and can be deleted temporarily to avoid calculating redundant boundaries. Fill it after deleting it, and then use this OOPS command to undo the graphics that have just been deleted.

measurement list LI or ls-every time an independent geometric object is drawn, CAD gives it information, which can be used to view relevant information. Generally, we use it to view the area and perimeter of a closed figure.

cleaning pu —— cleaning blocks, dimension styles, text styles, layers, etc. that have been used before and are not associated with use at present. Generally, executing the drawing after a stage can reduce the file size.

layer LA—quickly open the layer manager.

color COL—open the color manager quickly.

linetype LT—open the linetype manager quickly.

line width LW—open the line type manager quickly. Since color printing is almost always set at present, the setting of line width is unnecessary.

measuring distance di-measure the distance between two points and the included angle formed by the connecting line between these two points and the horizontal line. It plays the role of simple query, and is often used to view the brief information of lines when drawing.

query area and perimeter AA—it is mainly used to query the closed figure of non-polyline. If it is a closed figure with polyline attributes (such as rectangle, etc.), you can quickly query the area and perimeter directly with the LS command.

The software system will automatically reduce the display line segments to improve the running speed when drawing the regenerated model Re-CAD. For example, some circles look like polygons, which is the reason. Executing this command can display them completely.

Dividing a constant into divisions—This is a very useful command. When drawing, it is often necessary to divide a line into several parts to draw details, which can save calculation time.

equal division at fixed distance me-with the above equal division at fixed distance, the function of equal division at fixed distance is not great, and it is not as convenient as equal division at fixed distance.

edit polyline PE-if the existing line is not a polyline, executing this command will prompt you whether to merge it into polylines first. So this command is also used to merge straight lines into polylines.

edit block definition BE—when this command is executed, a dialog box will pop up where you can select one of the blocks to edit. But in general, we need to edit the block and double-click it.

define block attribute ATT—used for DIY blocks. The blocks with defined attributes can be used once and for all, and it is also very convenient to use, so it is necessary to master it.

transfer to drawing PS-when you enter the model operation in the layout space, you sometimes need to transfer to the drawing level. You can double-click or use this command.

switch to model ms-when operating at the drawing level in the layout space, it is necessary to switch to the model. You can double-click or use this command.

graphics repair manager DRM-when the software is closed due to power failure or software, you can use this tool to open the last automatically saved file, and the time of automatic saving can be set in the options.

linear ratio
