History of AutoCAD

Before AutoCAD, most CAD programs ran on minicomputers, with each CAD operator (user) working at a separate graphics terminal connected to a mainframe computer. The software would draw a model, export the graphics data to the mainframe computer, process the data in the mainframe computer, and return the processed data to the graphics terminal. At the graphics terminal, the operator could then export the graphics data as an image to film or paper for presentation to clients. To do this, the operator used the so-called “film command,” which could either be used in the context of traditional “B-and-F” printing or in the context of rotary printing.

AutoCAD, along with similar programs, enabled the operator to create and edit graphic images directly on a graphics terminal, without running a separate instance of the mainframe computer. The user would select a command in the graphics terminal to “draw,” and the result would be displayed immediately. Commands to draw in AutoCAD include the line, circle, arc, ellipse, polyline, polygon, spline, circle with center, path, polyline/arc, polyline/circle/arc, polyline/arc/circle, polyline/polygon, polyline/arc/circle/polygon, polyline/polygon, arc/circle, arc/circle/polygon, arc/polygon, polygon/arc/circle, polygon/arc/circle/polygon, polygon/polygon, circle, circle/polygon, circle/polygon/arc, circle/polygon/arc, and line/arc. AutoCAD also has commands for text.

Key features of AutoCAD

One of AutoCAD’s key features is that it includes “dynamic” technology. Dynamic means that new commands can be added to the software at any time. Dynamic technology means that the commands cannot only be stored on the disk drive, but are actually executed by the computer itself, so that AutoCAD can perform new commands as they are created. This means that new commands can be created and added at any time, and also that there is no need to wait for the installation and deployment of a new release of AutoCAD.

AutoCAD also has “variable” technology. Variable technology is the ability to make the software “responsive.” It means that the user can create objects at any location and

There are different versions of AutoCAD. Most people use AutoCAD 2016 (formerly AutoCAD LT) because it was the first to support Windows 10. AutoCAD 2017 (formerly AutoCAD LE) is required to run legacy applications. However, some of AutoCAD’s functions can be used in all versions of AutoCAD, including some functions for command line automation.

Document creation and manipulation

Drafting and design

Model tools

AutoCAD supports drafting and design tools including the following:
Scale tools for making sure the objects in a drawing are the right size. This includes the AutoCAD Protractor, which is used to control the scale of drawings (e.g. the length of the sides of building walls), and the AutoCAD Coordinate or Facing tools, which are used to guide the placement of an object in space.
Layouts: used to group and sequence objects.
Graphical annotations tools for adding text and lines to a drawing
Scene management tools for managing the drawing and objects on the drawing canvas
Reference tools for copying objects from the original model to the drawing
Placing tools to place the objects on the drawing canvas


Rigid and non-rigid modeling tools used to create 3D models:




AutoCAD supports multiple methods of 3D viewing:
Orthographic (planar) view: used to observe a cross-section of the model without changes in the model’s perspective.
Isometric (perspective) view: used to observe a 3D model from a constant angle and distance. This is an alternative to orthographic view, but is not completely analogous to a 2D drawing.
Camera view: used to view the model from any angle. This allows the user to see the model as if they were standing next to the model.
The Stereographic (topographic) view is a projection of a 3D model onto a 2D plane.

Measurement and dimensioning

AutoCAD supports a variety of methods for measuring and dimensioning objects in a drawing:
Using dimensions to specify lengths, widths, heights, and angles (lengths are the longest dimension, widths are parallel to the longer dimension, heights are perpendicular to the longer dimension, and angles are perpendicular to the longest dimension).
Using either the AutoCAD centerline dimensioning or

OS X The access command was denied by the operating system

This is a puzzling problem and I’m wondering if anyone has encountered this before. I’ve installed OS X El Capitan on a new Mac Mini and I keep getting this error:
The access command was denied by the operating system.
I can navigate to any directory on the computer and it opens just fine but when I click on any of my desktop icons I get the error. This happens in Safari, iTunes, Finder and all other apps that request access to the desktop. I’ve already tried rebooting twice, I’ve cleared all caches and there’s nothing in the system preferences or anywhere else that could be the source of the problem. Anyone have any ideas?
I’m guessing this has something to do with the new security settings. I changed my password and then logged out and back in and this resolved the problem. I’m just wondering if there’s a setting in the new system that I’m missing or anything else that could explain it.


I had this problem with 10.10. I was playing around with changing my account permissions and making sure my admin privileges were up. It eventually was an issue with permissions that were confusing my login screen with my admin login.
Try removing/reinstalling your admin password.


I encountered the same issue, and found the resolution on another post. I will update this when the answer is confirmed. It is the same answer as the one in the post I linked to, so it seems like the issue was resolved in El Capitan by Apple.
I’m not sure which specific setting was causing this issue for me, but I did see that something was added in El Capitan which was throwing up the error message.
