What’s new in AutoCAD 2020

Added a dark theme, which is much more convenient in terms of reducing eye fatigue when working in the program for a long time.

The highlighting of contextual tabs on the ribbon is now more distinct when it is active, for example, when editing text or creating hatching.

How to insert a block in AutoCAD 2020.

There are currently several methods available for inserting blocks: insert, tool palettes, and design Center. The presence of these different options, recognizing that people in different disciplines have different requirements and preferences.

The main reason for changing the design of the insert dialog box is to provide a better visual preview of blocks in the workflow for inserting blocks. The palette improves the efficiency of searching and inserting multiple blocks, including a new re-placement option that can save you a step.

Key features in the new block palette make it easier to efficiently set and insert blocks from the most recently used list or from specified drawings. Three tabs provide access to the following
• * the current drawing tab displays all block definitions in the current drawing, either as icons or as a list.
• The recent tab displays all recently inserted blocks, regardless of the current drawing. They are saved between drawings and sessions. You can delete a block from this tab by right-clicking it and selecting Delete from the recent list.
• On the Other drawings tab, you can go to folders from which you can select drawings to insert as blocks or select one of the blocks defined in these drawings. These drawings and blocks are also saved between drawings and sessions.
The upper part of the palette contains several controls, including a field for applying wildcard filters to block names, as well as several parameters for various thumbnail sizes and list styles.

How to clear a document in AutoCAD 2020 from unused primitives.

The cleaning function (the PURGE command) has been revised to make it easier to clean and organize the drawing. The control settings are almost the same, but the orientation is more efficient, and the preview area can now be changed.

How to find and delete duplicate objects in an AutoCAD 2020 document.

Another new and useful command is the ability to delete duplicate objects this is especially useful if these objects can not be visually determined that is, they completely match in shape and coordinates. To call this command, type OVERKILL in the command line.

How to measure objects in AutoCAD 2020.

Measurement is much faster thanks to the new quick option of the MEASUREGEOM command. Use this option to quickly view dimensions, distances, and angles within a 2D drawing.
If this option is enabled, the command dynamically displays dimensions, distances, and angles within the 2D drawing when the mouse cursor hovers over and between objects. The orange squares displayed on the left side of the drawing represent angles of exactly 90 degrees.

Graphical settings in AutoCAD 2020.

AutoCAD now runs correctly with various DirectX drivers (Dx9, Dx11, or without drivers), high-resolution (4K) monitors, and dual monitors. In addition, the graphic display settings are combined into three modes, which include gradient hatching and images. Graphics performance tuning, intermediate mode, is updated to automatically reset multiple display parameters to optimize your display. Settings are made using the GRAPHICSCONFIG command.

How to change the zoom speed in AutoCAD

In AutoCAD, you can use the mouse wheel to zoom objects on the screen, but the step or speed of zooming is not always acceptable to the user. This is especially true if the objects are very large or very small.

To change the zoom step or speed in AutoCAD, use the ZOOMFACTOR system variable.

Enter the ZOOMFACTOR system variable and specify a value of 15 or 20 instead of the default value of 60.
Zoom in or out with the scroll wheel.

As a result, zooming (zooming) becomes smoother and more accurate.

If you need both precise scrolling with the mouse wheel and long-step scrolling at the same time, create custom buttons on the ribbon panel or toolbar so that you can use them to set specific values for the ZOOMFACTOR system variable.

How to make a classic workspace in AutoCAD 2018, 2020.

In AutoCAD 2018, 2020, etc. the built -in command to quickly go to the classic workspace similar to previous versions of AutoCAD with menus and toolbars instead of the bookmark feed is missing.
To create a classic workspace in AutoCAD 2018, 2020, follow these steps:

  • Enable menu display. To do this, select the «Adapt quick access toolbar» button in the window header.


  • Disable the tool feed do this, enter the command RIBBONCLOSE in the command line and press Enter.
  • To enable displaying the necessary toolbars for this on the tools menu, click Toolbar.

  • In order to switch between different workspaces, you must save the configured workspace. In the lower-right corner of the screen, select Save current as from the drop- down menu.



How to set the line thickness in a drawing for printing in AutoCAD

According to the same requirements for drawings, lines with different purposes must have the appropriate thickness. To avoid cluttering the drawing and make it easy to create it, AutoCAD allows you to set the line thickness directly when printing. In this method, AutoCAD maps the line color to a predefined thickness value. You can set the thickness value for each color of an object in a document by selecting and editing the print style Sheet in the print settings window.


The most commonly used printing style is Monochrome.ctb in this case, the drawing will be printed in black and white.

After selecting a print style, you must edit it by clicking the button next to the drop-down list.

In the style editor, on the Card tab, assign each line color that is used in your drawing the appropriate characteristics, including the line thickness in the line Weight drop-down list.

How to add a plotter in AutoCAD to print DWG to raster formats

The article describes how to print a drawing from AutoCAD to a jpg file, however, by default in AutoCAD there is no plotter in the print settings for printing to a jpg, tiff, png, pdf file. Next, consider how to add the appropriate plotter.

We call the plotter manager. This can be done through the file menu, or by the _plottermanager command on the command line.

In the window that appears, a list of already installed plotters and the icon of the Plotter Setup Wizard will be displayed, it is just what you need.

Launch the Plotter Setup Wizard. A window appears in which you need to select the appropriate settings. For example, the type of plotter or printer to be installed.

We get to the choice of a plotter model, here in the list of Manufacturers you need to select Raster file formats, or Autodeask ePlot if you need to convert to pdf.

Next, select the model, that is, the type of raster file.

Set the name of the created plotter.

Now the created plotter will be available in the print settings in the lists of plotters (printers).

How to find the intersection of 3D solids (3D solid) in AutoCAD

When a document becomes a lot of 3D bodies visually determine the intersection between the bodies, especially if this intersection is small is very difficult. In AutoCAD for this there is a special command «Test interactions» it can be called from the «Edit» menu, the submenu «3D operations». You can also run this command directly from the command line by typing _interfere and pressing Enter.

After running the command, you will need to alternately select two sets of bodies.

The result of the team will be the creation of temporary objects-bodies or surfaces with the allocation of the intersection area of the models.

If the set of objects contains both 3D bodies and surfaces, then the resulting interaction object will be the surface.

For network objects, interaction checking is not performed. But if network objects are selected, they can be transformed into a body object or surface and the operation can continue.

How to create a parametric drawing in AutoCAD

All commands of this functionality are in the Parameterization menu.

The term parameterization means that the dimensions of 2D objects are set in the form of parameters that can have values, including in the form of a formula containing other parameters.

Consider a simple example of creating a rectangle in which one side will always be twice as large as the other.

First, use the _line command to create an arbitrary rectangle.

Next, we impose geometric dependencies on individual elements of our drawing (lines, points) by choosing the corresponding item in the Parameterization menu.

In particular, we use the coincidence between the points of the lines and the perpendicularity between the three lines, as well as the horizontalness of one of the horizontal lines of the rectangle.

We set the dimensional dependencies by choosing the appropriate menu item Parameterization.

We will choose one size horizontal and the other vertical values ​​will be left by default. Next, change the values ​​of the size parameters by double-clicking on the corresponding size. The value of the vertical dimension parameter d2 is set to 200, and the horizontal parameter size d1 is set in the form of the formula d2 * 2. Now, when d2 (vertical size) changes, the d1 parameter (horizontal size) will automatically change and will always be twice as large.

How to create and manage a group of objects in AutoCAD.

A group in AutoCAD is a named and saved set of objects. The user can select and edit both the entire group and its individual objects. Groups are useful for managing multiple graphical objects in a consistent manner. You can create them quickly by assigning them default names.
Groups are useful for linking 3D bodies when you do not want to join them using a Boolean operation.

You can add or exclude items from a group at any time.

To some extent, groups resemble blocks, which also combine objects with a name, but in a slightly different way. For example, groups can be saved for use in future work sessions. The difference is that the user can edit individual objects in a group, whereas when working with blocks, you must first break the block into individual elements. Unlike blocks, groups cannot be used in other drawings.

When creating a group, objects are selected, its name and description are specified.

When you create a group, you specify its name and description.

When you copy a group, the new copy is named Ax by default; the new group is considered unnamed. Unnamed groups are not listed in the object Groups dialog box unless the Include unnamed option is selected.

If you select at least one element of the selected group, all its elements are included in the new group.

An object can belong to more than one group at a time, and a group can belong to other groups. You can Ungroup nested groups to restore the original group configurations.

When you use a drawing as an xref or insert block, named groups within the drawing are not available. However, the user can embed and then dismember an xref or block, after which the groups are made available as unnamed groups.

To create a group, you must type in the command line _GROUP, if you type-GROUP command parameters are displayed.

When group selection is enabled, groups can be moved, copied, rotated, and edited in the same way as individual objects. To edit an individual object in a group, turn off the group selection mode or use the handles on the object.

In some cases, it is useful to control the order in which objects belonging to the same group are selected. For example, a user program that defines toolpaths for numerical control may depend on a number of adjacent objects in a specified order.

Reordering elements can be done in two ways: either change the order of the individual elements (either one or more), or change the order of all elements. The numbering of group objects starts with 0, not 1.

How to quickly change the properties of selected objects to Layer values

In AutoCAD, you can use the layer COMMAND to change the specified properties (color, line type, etc.) of selected objects to Layer values. The values of the by Block parameter for objects can also be changed to Layer values. Objects whose properties are not set to Layer do not display layer property overrides set by the viewport.

To specify which properties are changed to Bylayer values in the team settings ASTROLOY after running the command via command line you have to press the right mouse button and select in the context menu setting.
