How to quickly create a 3D model of a sheet part in AutoCAD

How to quickly create a 3D body of a bent sheet part in AutoCAD.

— Using a polyline to build the profile of a bent part.

— using the squeeze command applied to the polyline, we build a plane by setting the size of the extrusion, for example, 200 mm.

— using the «Add thickness» command, type THICKNESS (_Thicken) in the command line and press Enter, applied to the plane to create a 3D body. Moreover, by setting the thickness you can specify a negative value then change the direction of building thickness.

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 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 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.

How to quickly select the desired objects in a drawing or 3D Assembly in AutoCAD

In complex Assembly drawings or 3D assemblies in AutoCAD, it becomes difficult to select the desired objects among many others for editing. To solve this problem, the useful AutoCAD function «Quick select» helps to start it, you must click on the button on the Properties palette.

Next, a window will open in which the conditions are set by which AutoCAD will select the desired objects among the set in the editor.

You can search the entire document or in a pre-selected area of the editor.

To select an object, you must set the object Type to its Property and the value that this property of the selected objects must match. For example, you can select all objects of only a certain color.

You can also add or exclude selected objects from the set.

How to squeeze an arbitrary cross section along a path in AutoCAD

Very often there is a need to build a 3D object of a certain cross-section along a complex path, such as piping, wiring, pipes, hoses of sleeves, etc. Such an object can be constructed using the EXTRUDE use the parameter Trajectory. We build the trajectory necessarily using the command POLYLINE geometry can be any.

We construct a section, which we will squeeze out, necessarily perpendicular to the trajectory, in our case, it is a circle.

Select the command to SQUEEZE. In the command prompt, enter «T» (for the Russian version of AutoCAD) ie squeeze sweep. Receive result.
