AutoCAD Crack + Activation Download For PC [Updated] 2022
The earliest AutoCAD drawings were described in engineering reports. Many of these drawings were produced on paper and then scanned and digitized by people using various computer programs. These digitized drawings were typically stored in a proprietary format, thus making them difficult to exchange with other vendors and drawing stations. CAD (computer-aided design) allowed these drawings to be stored in a more universal CAD format.
Today, AutoCAD is the mainstay of commercial CAD. The large, international, highly technical user community has had significant influence on the development of AutoCAD and other related products.
Like all software applications, AutoCAD has a specific product version. It is important to use the latest available version, as AutoCAD updates and new features are not guaranteed to be backward compatible.
You can download free trial versions of AutoCAD at the Autodesk site.

3D modeling 
AutoCAD LT 
AutoCAD LT has basic 3D modeling capabilities that allow users to model simple objects. You can use polyline, polyline with standard, polyline with polyline, circle, circle with circle and arc objects, and spline objects.
 Advanced 3D modeling 
AutoCAD LT 2011 
AutoCAD LT 2011 has several 3D modeling features, such as splines, polylines, surfaces and mesh tools. These features give users the ability to model complex objects. These features include the ability to extrude and revolve multiple profiles, subtract and subtract profiles, use standard, split and union surfaces, create complex splines, edit meshes and remove components of a mesh.
 3D modeling tools in AutoCAD 
Revolve and extrude tools 
Revolve and extrude are two main tools used in 3D modeling in AutoCAD. These tools allow you to model any kind of object.
Loop cut and join 
The loop cut and join tool allows you to cut and join faces together.
Perspective 
The perspective tool allows you to create and modify complex 3D objects.
Reverse engineering 
The reverse engineering tool allows you to model complex 3D objects in one step.
Surface and sketch editing 
In AutoCAD LT, surfaces and sketches can be used in many ways. The surfaces tool allows you to create a 3D surface on an existing 2D surface. You can also make complex 3D shapes by using surfaces.
The sketch tool allows you to create 2D shapes and faces for use in 3D modeling. Sketch objects can also be modified using the reverse engineering tools.
Face tools 
AutoCAD LT uses face tools to create, edit and modify 3D objects. These tools include:
Faces
Edit face 
The Edit face tool allows you to open, modify and close faces for various purposes. For example, you can close a face to generate a non-manifold surface or use the open face command to add a new face to a closed face.
Modify face 
The modify face tool allows you to create new faces, delete faces, modify edge loops, remove sharp faces and merge faces.
Clip 
The clip command allows you to create a closed shape from multiple faces.
