AutoCAD Civil 3D Full Version
AutoCAD Crack+ [32|64bit]
Today, AutoCAD is used throughout the design industry to create drawings, technical documentation, and other forms of two-dimensional (2D) content. It is also used in industry, government, and academia to create three-dimensional (3D) content. AutoCAD is used to create models in civil engineering, architecture, structural engineering, landscape architecture, interior design, industrial design, mechanical design, electrical design, and other fields. CAD is a separate discipline from computer-aided manufacturing (CAM), which is the application of CAD in manufacturing.
CAD software is used to create or modify drawings and other types of 2D content. A drawing is a collection of connected lines, arcs, planes, text, and other graphical elements. Drawings are typically created on paper using a drafting tool, such as a pencil or pen, and a drafting tablet. The draftsperson draws and connects lines and other elements using input devices such as a stylus, trackball, or mouse to manipulate the graphical elements.
Drafting tablets are used for electronic drafting. Electronic drafting is commonly done on a touch screen. Electronic drafting eliminates the need to hand-draw on a drawing surface. This allows a CAD operator to draw more complex and faster. Electronic drafting can also allow the CAD operator to select a style of drawing, such as a line style or a freehand or stroke style. AutoCAD lets the operator choose the most appropriate style, based on the drawing. The stylus or pen used with electronic drafting is a pointer device. The operator manipulates the pointer device to create and modify the graphical elements.
CAD software and CAD content is also used in industry, government, and academia to create or modify 3D content. A CAD model is a collection of surfaces and other geometric elements in a modeling language.
Modeling languages allow the CAD operator to create and manipulate the geometric elements of a CAD model, independent of the type of model. Many of the modeling languages supported by current CAD software also offer programmatic access to the CAD model via a high-level interface language (HLL). Many CAD applications are available as a native application on the same computer or system that the CAD operator uses to create 2D content.
CAD software is used to create 3D content in a variety of applications, including civil engineering, architecture, structural engineering, landscape architecture, interior design, industrial design, mechanical design, electrical design, and other fields. CAD applications can

Autodesk AutoCAD runs on Windows, macOS and Linux (both natively and via cross-platform emulator Virtualbox). It also runs on the Android platform, but currently only allows users to open.DWG and.DWF files (the native Android CAD format).
Autodesk AutoCAD is free for personal use, open source projects and academic use. The company also offers a cloud-based subscription model.
The basic user interface (UI) is similar to those of CAD packages such as AutoCAD LT and GIS packages such as ArcGIS, although AutoCAD has no GIS or asset management functionality. The basic UI is based on the Microsoft Windows theme, and includes the standard components of a Microsoft Windows desktop: the File, Edit, View, Tools, Help and Options menus; the Start menu; a System Tray (with the Sync clock) and the taskbar.
Since version 2005, AutoCAD is based on Microsoft Windows Presentation Foundation (WPF), and its interface includes a left panel. The basic window layout is simple and common, but customizability of the interface has allowed a wide variety of customizable user interfaces to be created, including skins and themes. In addition to the standard UI elements, AutoCAD provides support for Windows XP's Taskbar, which allows the program's main window to be docked to the taskbar as a shortcut.
The user-defined toolbar is customizable and may be customized to suit a user's preferences. It is located in the bottom-right corner of the window, to which various commands may be assigned by placing the mouse cursor over the image.
Toolbars and ribbons
AutoCAD contains a number of customizable toolbars and ribbons. These are the same ones that appear when the Autodesk Navigator window is selected as the main interface, but they may be customized to suit individual users.
The menu ribbon, located in the upper-left corner of the window, provides access to menus in the Program's Window.
The Recent menu provides access to recent drawings, users, AutoCAD sessions and drawing data that have been opened within the past ten minutes.
The Help ribbon provides access to a variety of online documentation sources. The Online Help Index page,

r data.table conditional join
I have a large data.table, and want to join it to another data.table based on a column with the same name in both data.tables. The conditional would be if the value in the 2nd data.table is less than the corresponding value in the 1st data.table.
I'd like a solution without using sqldf.
How could I do this?
The 2nd data.table looks like this:
structure(list(V1 = c(22, 11, 24, 14, 11), V2 = c(45, 24, 15,
36, 34)),.Names = c("V1", "V2"), row.names = c(NA, -5L), class = c("data.table",
and the 1st data.table looks like this:
structure(list(V1 = c(20, 12, 23, 13, 10), V2 = c(34, 35, 15,
36, 35)),.Names = c("V1", "V2"), row.names = c(NA, -5L), class = c("data.table",
I want a result that looks like this:
V1 V2 V3 V4 V5
1: 22 45 NA NA NA
2: 11 24 NA NA NA
3: 24 15 NA NA NA
4: 14 36 NA NA
