You can use this tool to make a Breakline symbol on a line. 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. There are many best practices that you follow to keep your AutoCAD software and PC in great working condition and there are also many inbuilt tools and commands in AutoCAD that help you in keeping the performance of your software properly optimized.
In this section, you will find all those performance and optimization related commands which you can use in your daily workflow. This command can be used to remove unused named objects like layers, blocks and dimension styles from the drawing. 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.
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 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 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.
Its default value is 1 but you can turn off this highlight effect by changing its value to 0. 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 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. 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. This system variable suppresses the dialog box that opens up when invoking certian commands like Save, Save As and Export. The default value of this system variable is 1 which allows the dialog box to open.
When you, however, change the value of this system variable to 0 the command will run on the command line and the dialog box will not open. This command should be used for removing errors from your drawing. 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. 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. Using this command you can convert your AutoCAD drawing from one unit to another and you can also scale the existing drawing to new scales automatically, you can know more about this command in the related article.
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. 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.
This tool was added in the AutoCAD 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. You can learn more about this command on this AKN page. These commands will help you in making your overall drawing workflow faster and efficient by eliminating the need for using many repetitive tasks.
It is always a great practice to use as fewer steps as possible to keep the drawing workflow easy and also to avoid unnecessary data in your drawing, and the commands of this section will help you in achieving just that. 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. This command will redirect you to BIMobject. 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. 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 print multi-sheet files directly, unlike PLOT command which only plots single sheet this command will allow you to plot multiple sheets or even all of the sheets of the drawing directly. 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.
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.
This command can be used to bring Design Center palette in the drawing area. To know more about the 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. If you want to export a 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. You might be familiar with many of these commands but there are also many commands which are not frequently used despite their great features. 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.
Using this command you can make a 3D wall-like shape as shown in the image here, you can also define height and thickness of this poly solid using command line options. This system variable controls the behaviour 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.
You can extract edges of a 3D solid as 2D geometries using this tool. In the image shown here the XEDGES tool has been used to extract the edges of the 3D solid and then the solid geometry has been moved to reveal the edges only.
This command was introduced in AutoCAD 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.
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.
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 align a 3D solid object with respect to another 3D solid, this video explains the use of this command in detail. 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 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 imprint 2D drawings on planar faces of a 3D solid or a surface to create additional faces for 3D tools like Presspull. Did we miss any command or tool which should be included in this list? Let us know in the comments below. L It can be used for making simple lines in the drawing.
