Autodesk Animation Academy Autodesk Design Academy AutoCAD for Mac Autodesk AutoCAD is a complete application for a computer-aided design that provides a comprehensive set of tools for engineers and designers while working with 3 Dimensional designs. It has become a standard in the world of design.
With state of art drawing and designing tools, the users can design almost anything without any trouble. Command-line support allows passing different parameters to the application. It is specially designed for professional 3D designing.
Students can also get complete control over the designing tasks while working on this powerful application. It provides advanced 3D designing is not the only feature of AutoCAD, but you can also create architectural patterns. It is the best tool to improve the designing process. So far, no product is available in the market which is as much efficient as AutoCAD.
It has also revealed the power of the cloud in the field of designing. You can also download AutoCAD As a cross-platform product that can collaborate with other platforms and workflows.

Let’s see some particularities and 3D applications and learn that a whole bunch of known commands can also be applied. Basically, all drawing commands can be used in 3D, provided that we have the correct working plane, LINE being the exception. But circles, arcs, and polylines including polygons and rectangles are drawn on the working plane called active coordinate system or a plane parallel to the working plane.
Some commands work only on the objects plane, not necessary the active working plane. This allows for cutting or extending objects that, in the current view, seems to be on the same plane, but are really on different planes.
Now, we have three different commands for rectangular, polar, and path arrays. Among multiple options, there are two with special importance for 3D: Rows , where we can define a number of rows with a height distance, and Levels also with a variation in height. No one can use AutoCAD without inquiring for information from time-to-time.
Blocks work exactly the same way in 2D or 3D. When inserting a block with non-uniform scale, we can specify a different scale for the Z direction. Regions are 2D opaque closed objects that are frequently used in 3D. Besides 3D, they can be very useful for extracting areas, inertia moments, and other geometric properties.
To create regions, we must have their contours already drawn. Contours can be lines, arcs, circles, ellipses, elliptical arcs, and splines. In 2D, regions are created with two commands:.
It only prompts for the selection of objects and the original objects by default are deleted. An example follows. We are going to create some 2D objects and from them, some regions. For now, dimensions are not important. On the dialog box shown in Object type list, choose Region. Select the Pick Points button. The dialog box disappears. Specify the four points inside the closed area, shown on the image and press Enter. The four regions are created. Freeze layer 0 to view only the regions.
Regions are opaque. Choose the Realistic option:. We can apply thickness to most linear 2D entities and also create linear 3D entities like 3D polylines and splines. Almost all linear entities that we know from 2D have a property called Thickness, whose value represents a height along the Z axis a better word actually should be height. A line is still a line or a text still text, but with a proper visualization, these entities can transmit a 3D feeling:. These polylines are designed by lightweight polylines.
But what if a single object is needed to be composed by segments whose endpoints have different Z coordinates? The answer is to create 3D polylines. Three processes are available:. It works like the LINE command, but the result is a single object. It is enough that one endpoint of a line is out of the plane for a 3D polyline to be created. The first object must already be a 3D polyline.
Starting with version , the best way to apply the JOIN command is to select all the line segments at the first command prompt, without specifying a source object. Depending on the type of selected objects and their positions, the most suitable object is automatically created. The creation of 3D solids and surfaces from linear objects is the subject of Chapter 4 , Creating Solids and Surfaces from 2D. Splines are smooth linear objects, normally without corners that pass through or near specified points.
Splines are described by a set of parametric mathematical equations, but have no fear, for AutoCAD will internally deal with this, we will not have to! Splines are used whenever we need smooth curves and are also the foundation for NURBS surfaces, the most used surfaces in the automotive or aeronautic projects. To create a spline we apply the guess?
By default, the command only prompts for the location of fit points, and the spline passes through the specified points. An Enter finishes the spline and the Close option creates a closed spline.
When selected, the small blue triangle allows switching between Fit points and Control vertices. To edit a spline is very simple: we select it, without command, and work with grips. We can either click a grip and move it, or we can place the cursor over a grip and on the grip menu choose to move the vertex, add one, or remove that vertex. This last process is known as multifunctional grip. We may have a contiguous and non-planar sequence of lines, arcs, elliptical arcs, splines that the result is a single spline.
By default, the command prompts for the center point of the base, base radius, top radius, and height.
