For easy classification, I have divided all commands into four categories.
This command is useful for counting number of blocks in your drawing. It reports the number of each instance of block used in the drawing along with its name. To count the block it should be visible in the drawing area.
Using this command you can convert single line as well as multiline text into geometries.
Using this command you can make infinite lines starting from the point of selection. When you trim or break this infinite line to a finite length it becomes a simple line geometry.
This command makes a single point geometry in the drawing. To modify the type of point created by this command you can use PTYPE command and choose te desired point type from Point Style window.
Using this command you can make a revision cloud geometry by freehand sketching.
You can make a freehand sketch using this command. You can use Line, Polyline or Spline as the object type for making this freehand sketch.
If you want to repeat any command without pressing enter key then use MULTIPLE command. To cancel repetition of command press ESC key.
Use this command to copy nested objects from a block or Xref without exploding them.
Using this subcommand you can perform calculations directly on the AutoCAD command line even when you are in the middle of a command. You can start this subcommand by entering ‘CAL (don’t forget to add an apostrophe before CAL) while running any other command.
To know more about this subcommand refer the related article.
Explodes the block containing attributes retaining the attribute setting and its layer definition. This is especially helpful if you want to retain the text of attribute after exploding the block.
Using this command you can check the spelling of selected text and correct the spellings from Check Spelling window.
This command can be used to write arc aligned text in AutoCAD. You can use this command to even write text aligned to a circle. More about this command can be found in this related article.
This command can be used to restore the last deleted object in your drawing. After deleting an object if you made many other changes in the drawing and realized that you might need to restore the deleted object then simply type OOPS and press enter.
This command can be used to change the space of an object from model space to paper space and vice versa. See the animated image shown below for reference.
You can use this command to divide any 2D geometry into many equal parts. At each point of division, a point geometry will be added on the 2D curve. More about this command can be found in this related article.
If you need to rename any named object like layer, block or linetype simply use this command to rename it. More about this command can be found in this related article.
This command can be used to break 2D geometries at one or two points. It is helpful if you want to break a curve at the point of intersection with other curve or if you want to create a gap by breaking a part of the geometry.
Using this command you can find a lot of information about your drawing like the date when the drawing was created and total editing time consumed on the drawing.
This command can be used to make the selection from your drawing with filters. As an example, you can use quick select to make a selection set containing all circles of the drawing with the radius of a particular value.
It can be used to find the distance between two points in the drawing.
Using this command you can copy any object using a base point.
You can paste the copied objects from clipboard to your drawing using this command. If you use COPYBASE to copy the objects then you will be able to paste it in the same or another drawing with the selected base point.
Using this command you can find lots of properties of an object like the layer they are on, area, length or radius, perimeter or circumference and a lot more. To use this command simply type LIST on the command line then press enter and select the object from drawing area about which you want to know and press enter again.
This command was introduced in AutoCAD 2016 version and it can be used to make most of the dimensions like Linear, aligned, radius, diameter and baseline. To access this command you can use DIM command or select the DIM tool from dimensions panel of Annotate tab.
If you want to add feature control frame representing tolerance related information in your drawing then you can use this command.
Using this command you can change the scale of existing Text or Mtext object in the drawing. To use this command type SCALETEXT on the command line press enter and select the text from drawing area and press Enter again.
Now select “Existing” option from the command line and then select “scale factor” option and then type the scale in which you want to convert the text height and press enter. When the scale of these text entities are changed the base point will remain fixed.
Using this command you can change the base point of a drawing without changing its origin. This is especially helpful in the situation where you want to insert the drawing into another as a Xref. By default, AutoCAD takes origin as the base point which can be modified using this command without changing the origin.
If you have a drawing open in AutoCAD and you don’t know the location where it is saved you can simply type DWGPREFIX command to look it. This command can be used to quickly find the location of Xref’s attached in the drawing.
Using this command you can change the text justification of Text and Mtext elements in the drawing.
Using this command you can set the drawing units and other settings like the precision of linear and angular dimensions and default rotation angle.
Using this command you can make a multiline geometry which contains multiple parallel lines.
You can insert a block or a drawing as a block in the table using this command. You can also fit the block in the table cell and also justify its location automatically with TINSERT dialogue box. I have made a simple table by importing blocks of design center as shown in the image below.
By default, AutoCAD does not mirror text in the drawing but if you want to mirror the text of your drawing then change the value of MIRRTEXT system variable to 1.
As the name suggests this command can be used to find the area of closed or open shapes in the AutoCAD drawing. To know more about finding the area in AutoCAD drawings refer this related article.
Using this command you can reorient text entities in best readable position. In the image A below the text is oriented at different angles and in some of the situations, the text is not properly readable. Whereas in image B below TORIENT command has been used to make the text readable for all angles.
This command can be used to find the coordinate values of a point in AutoCAD drawing.
Using this command you can insert existing blocks of a drawing as a rectangular array component. An array added using MINSERT command can’t be exploded.
Using this command you can extract closed boundaries from any enclosed area. This boundary can be used to find the area of the enclosed region or for many other applications. In the image below the boundary of the area mentioned as A has been extracted as a polyline using BOUNDARY command.
This command can be used to make a dimension line inclined to a particular angle with respect to the positive side of the X-axis. In the example shown below the dimensions are made with DIMROTATED command.
You can use this tool to make a Breakline symbol on a line. Type BREAKLINE on the command line and press enter then click on scale option of the command line and apply an appropriate scale to the breakline.
Select the starting and end points of the breakline then click at any point on the line to specify the location of breakline or directly press enter to place it exactly at the center of the line.
Using this command you can convert a text object into a Mtext object and you can also combine multiple separate Mtext objects into a single Mtext unit.
As the name suggests this command can be used to save all of the open drawings in AutoCAD window.
This command can be used to remove unused named objects like layers, blocks and dimension styles from the drawing.
Using this command you can delete some of the most stubborn layers from your drawing which can’t be removed using PURGE command. This command can also remove Defpoints layer and also layer containing objects but I would not recommend that.
Using this system variable you can turn off or on the visibility of filled area in hatches or wide polylines by changing its value to 0 or 1 respectively. By turning the FILLMODE to off you can enhance the performance of AutoCAD by limiting resources consumed on regenerating the filled geometries.
You need to regenerate the drawing using REA command after changing this system variable to see its effect on the drawing.
This system variable controls the area of influence of object snap. The aperture size as defined by this system variable is the area of the square under which the point will be selected if the cursor is brought into it. The default value of this aperture is 10 but depending on the complexity of the drawing you can change this value between 1-50.
The size of the aperture is relative to the current scale of the screen and it is not an absolute value. In the image below the red box (not visible in AutoCAD) is the aperture size for two values 10 and 50 respectively.
Use this command to remove overlapping or unnecessary geometries from the drawing.
You can change the value of this system variable to reduce the time it takes to save a drawing. This system variable also affects file size of AutoCAD drawings and its compatibility with other softwares.
By decreasing the value of this system variable you can increase its compatibility with other softwares and it also decreases the size of the CAD file but the time consumed in save operation generally increases. When you increase the value of this system variable opposite happens.
The default value of this system variable is 50 and it can be changed from 0 to 100.
When hovering the cursor over any object a preview will appear if the value of this system variable is set to 3. You can remove this preview thereby improve the performance by changing the value of this system variable to 0.
This system variable is also similar to SELECTIONPREVIEW but in this case, the object will appear highlighted when selected. Its default value is 1 but you can turn off this highlight effect by changing its value to 0.
This command repairs a corrupted or damaged drawing along with all of its attached Xref’s.
Using this command you can change the layers of selected objects. To use this command type LAYMCH on the command line and press enter key then select objects whose layer assignment you want to change and press enter then select any object of the layer which you want to apply on selected objects and press enter key again.
Using this system variable you can change the size of Pickbox which appears at the cursor of AutoCAD. The default value of this system variable is 3 and you can change its value from 0 to 50.
In the image below the size of Pickbox is 3 for first cursor and 10 for the second cursor.
This system variable will toggle the visibility of start tab at the beginning of the AutoCAD application. By default the value of this system variable is 1 which allows start screen to appear, you can change this value to 0 if you don’t want to see the start screen.
If you have multiple tabs open in your AutoCAD window and you don’t want to manually close them one by one then you can simply use CLOSEALL command to close all the open windows. AutoCAD will prompt you with the save dialogue box before closing all unsaved drawings and it will take you to start screen after closing all of the drawings.
Using this system variable you can make a selection of overlapping objects very easily. When the value of this system variable is set to 2, an overlapping icon and a menu containing a list of overlapping objects appear and you can select the required object from this list.
If you set the value of this system variable to 1, only the overlap icon appears not the menu. You can turn this off by changing the value of this system variable to 0.
This command should be used for removing errors from your drawing. It is always a good practice to keep checking your drawing file with AUDIT tool for errors.
This command is similar to the AUDIT command but it is useful for the drawings which are corrupted to such an extent that you can’t even open it. More about drawing repair tools can be found in this related article.
This command is a great time saver if you want to copy properties of one object on other without changing its geometry or contents.
Using this command you can close all open drawing windows except the current drawing window.
Using this command you can shrink or expand the text entities in a drawing to fit in the required area. In the example below I have fitted the AutoCAD text within the rectangle using TEXTFIT command.
Using wipeout command you can clean background in a crowded drawing to make overlaying objects clear against the background. In the image shown below Wipeout command has been used to clean the area around the second hook. You can use WIPEOUTFRAME system variable and change its value to 0 to remove wipeout frame boundary also.
Using this command you can automatically create a masking behind the text to make it clearly visible against the crowded background. In the image below Textmask has not been applied for the first case and in the second case, it has been applied.
If you want to merge layers of multiple objects then this command is for you. Type LAYMRG press enter key then select the objects whose layers you want to change then press enter again. Select any object of target layer on which you want to transfer the selected objects and press enter again.
All the objects of the selected layer will be transferred to the end layer and also the selected layer will be removed.
Using this command you can open the drafting settings window which can be used to change settings related to status bar options like object snap, polar tracking, snap and grid settings.
Using this command you can check all the objects which are on a particular layer. When you use LAYWALK command a list with all layers appears on the screen and you can click on any of the layer(s) from the list and objects from that layer(s) will only become visible in the drawing area. The original status of layer and object visibility is restored once you close LAYWALK window.
This tool was added in the AutoCAD 2017 version and it allows you to create center mark easily on a circle or arc.
As the name suggests you can add a centerline easily between parallel or intersecting lines using this tool. See the related article for more on Centermark and Centerline tools.
If for some reasons you are looking to use Tablet as pointing and navigation device in AutoCAD then you can use this command to turn the Tablet input on and off. The Tablet can be turned on and off using TABMODE system variable also.
You can learn more about this command in this AKN page.
This command will open a text window which has a history of recently used commands.
This tool can be used to modify the attribute information of blocks containing attributes.
You can use this command to Turn on/off hardware acceleration or change the graphics related properties of AutoCAD like smooth line display and high-quality graphics display.
This command will redirect you to BIMobject.com page (formerly Autodesk seek) which is a CAD and BIM object catalog. It is one of the great places to get blocks for your projects.
Using this command you can select objects which are connected to the selected object in the drawing area. The behavior of this command is controlled by FSMODE system variable, if the value of FSMODE is OFF then FS command will select only the selected object and one object that is directly connected to the selected object.
If the value of FSMODE is ON then FS command will select the selected object as well as all the objects connected to it and its next connected object in the series. This selection series continues as long as the command finds connected objects.
Using this command you can bring TEXT, Dimensions and Leader lines on the front of all underlying objects like hatches. This command is especially helpful if you want to bring multiple annotations to the front of all drawings objects without changing their draw order selectively.
Using this command you can hide all objects from the drawing area except the selected objects. By hiding unnecessary objects from drawing you can get a clean work area. To bring back all the hidden object back to the drawing select UNISOLATE or UNHIDE command.
This command is similar to ISOLATE command but in this case, you can hide selected objects keeping remaining objects visible. In this case, also you can bring back hidden objects by using UNHIDE or UNISOLATE command.
Using this command you can group multiple objects as a single unit. This command is great for making groupings of the similar type of objects like a group of similar blocks. To break this group you can use UNGROUP command.
This command can be used to bring Design Center palette in the drawing area. You can also use CTRL+2 key to open the design center palette. To know more about design center go to the related article.
Using this command you can import drawings of many different formats in AutoCAD, the list of all supported formats is shown in the image below.
Fields are dynamic text information which can add a lot of intelligence to your drawing by keeping data interlinked and updated. Fields are extensively used in the sheet set and layout drawings and they can be used to automate a lot of information in AutoCAD drawings.
You can start the Field window using FIELD command of AutoCAD.
If you want to export certain part of your drawing or any of its blocks to an external file then you can use write block tool or its command equivalent WBLOCK.
Using this command you can convert a surface into a 3D solid by adding thickness to it.
Using this command you can convert 3D mesh and watertight objects made with surfaces to 3D solid and you can also control whether converted solid is smooth or faceted.
This system variable controls the behavior or 2D curves when 3D tools like Extrude, Presspull and Sweep is used. You can change the value of this system variable so that AutoCAD either retains or deletes curves after converting them to 3D.
More about this system variable can be found in this AKN article.
Using this command you can find the volume of a 3D solid as well as lots of other information like its moment of inertia, radius of gyration, centroid, and products of inertia.
This command was introduced in AutoCAD 2017.1 update and it is especially helpful in removing the 3D graphics related anomalies and surface tessellations.
Using this command you can create a section plane in the drawing that can be used to see the 3D drawings by sectioning them along different planes.
This command is great for converting a 3D drawing into 2D and using this command you can also create multiple views of a single 3D drawing like the front, top and isometric on a single plane. To know more about this command follow the related article.
This command can be used to detect intersecting 3D solids. The command is especially useful in situations where you want to detect clashes between different solids like pipes and walls.
Using this command you can project a 2D curve on a 3D surface, solid or region as shown in the animated image below.
Using this command you can convert a 3D solid into a hollow solid with a wall thickness. To use this command type SOLIDEDIT on the command line press enter type B press enter again type S and press enter again. Alternatively, you can also select the shell tool from Solid editing panel of the Solid tab.
Using this command you can fill the open areas of a surface like the top of a cylinder as shown in the animated image below.
As the name suggests this command can be used to make a helix in AutoCAD drawing.
Using this tool you can move faces like a groove of a 3D solid from one point to other as shown in the animated image below. For using this tool type SOLIDEDIT on the command line press enter then type F press enter then type M and press enter again.
This command is similar to the trim command of 2D drawings but in this case, it will trim surfaces instead of 2D geometries.
Using this command you can offset any surface inside, outside or on both sides of the surface as shown in the animated image below.
Using this command you can imprint 2D drawings on planar faces of a 3D solid or a surface to create additional faces for 3D tools like Presspull.
Using this tool you can record the history of solids on which boolean operations are performed and you can modify these solids later.
In the image below Subtract operation is performed on two solids and then the amount of removed part is changed by selecting the Cone by pressing CTRL key then changing its base radius.
By default, the value of this system variable is 0 which keeps this feature off but you can turn it on by changing its value to 1.
Using this command you can align a 3D solid object with respect to another 3D solid, this video explains the use of this command in detail.
