how to draw 3d in autocad 2007 pdf

We have taken a good time lately working on mastering the basics in AutoCAD, and with this skill, you must exist able to replicate any second images using AutoCAD.

As you must accept noticed from our by experience, learning AutoCAD goes first with understanding what the environment is made of, How to describe basic shapes, and finally how to combine all the basics to create complex designs.

AutoCAD 3D features

Before diving into creating your first 3D drawing in AutoCAD, I would like to throw the following.

AutoCAD is primarily for generating 2nd sketches. It does have some ability to visualize those 2d sketches in 3d, and fifty-fifty to brand 3d objects, merely it's primarily built around a flat, sketch-based workflow. If your invention is fundamentally two-dimensional, or made of trivially interlocking 2d parts, AutoCAD might be the right thing.

Inventor is for 3d product design. It'due south a professional piece of software and takes quite a fleck of time to learn, but that'south also true of its direct competitors. It'south currently Autodesk'south most powerful tool for mechanical design. I can't requite you a coherent feature comparison to SolidWorks or Creo considering I don't know them well enough; I practice know that SolidWorks is more popular. Inventor is second, I think.

We practise accept a adequately new product called Fusion 360. It's congenital on the aforementioned modeling kernel as Inventor, and has amend gratuitous form modeling. It's designed to be an all-in-one package for product pattern by hobbyists and small businesses. We focused on making the user interface equally easy to learn as possible. It'due south nevertheless quite a new product, and gets updates every few months, partly based on user feedback from its forum. A major reward is that it'southward costless until you start making money with it, and even after that it'southward pretty inexpensive.

Adam Helps ( Software Engineer at Autodesk )

No need to elaborate further, but be aware that there are some industries (like Structural Blueprint, Civil engineering science) where AutoCAD is the preferred CAD software for 3D cosmos.

Surface Modeling and Solid Modeling

While talking most AutoCAD Drawing and CAD, it is important to know the difference betwixt Surface Modeling and Solid Modeling.

Surface modeling CAD (Blender, Sketchup, Rhino, Maya) deals with manipulating the curves and surfaces of a model. It'due south more than gratuitous class and generally washed by clicking and dragging the surface/curves around to your liking. Information technology'southward platonic for architects, jewelry blueprint, or anything y'all desire done aesthetically.

Solid modeling CAD (Solidworks, Inventor, ProE, SolidEdge, GeoMagic) deals with calculation dimensions and constraints to a 3d model. Information technology is "parametric" pregnant you can ascertain the shape and later edit. This is very essential for engineers since design changes are always happening. Great for mechanical parts that require constant iterations. Some solid modeling CAD can perform surface modeling merely it'southward a nightmare.

AutoCAD 3D modeling 101

The post-obit image shows you an overview of what the object is made up of.

All objects are arranged like this

The elbow:

Creating basic 3D AutoCAD cartoon

Before fully diving into this, you should make sure all tabs are activated. (Correct-click to show the carte du jour)

Creating a Cylinder

To create a cylinder

1. Click on Cylinder
2. Specify the center of the base of operations
3. Specify base radius
4. Specify the height of the cylinder

Other routes you can use to create a cylinder are the post-obit.

Using the EXTRUDE command

1. Create a Circle
2. Use the extrude command to obtain the cylinder

To practise that

1. Create a circle the fashion we learned
2. Type EXTRUDE and press ENTER
3. Select the circle and printing ENTER
4. Specify the peak of extrusion

Using the REVOLVE command

1. Create a rectangle
2. Use the Revolve control to obtain the cylinder

To do that

1. Create a rectangle using the RECTANGLE command
2. Blazon REVOLVE and Press ENTER
3. Select the rectangle and Press ENTER
4. Select ane of the ends of the red line shown on the paradigm above
5. Select the second terminate
6. and printing ENTER

Using this method, you can at the last step decide not to shut the cylinder, pregnant yous will have to enter an angle value less than 360 earlier pressing ENTER.

Creating a sphere

To create a sphere

1. Click on sphere
2. Specify the center of the sphere
3. Specify the radius of the sphere

Create the last piece of that elbow

Simply create a triangle and extrude information technology. (use the POLYLINE command to create the rectangle). You can equally well utilise the WEDGE command to create information technology.

We have pretty much created all basic 3D objects we need, now we need to create copies, rotate them and assemble everything.

We have seen quite a number of new techniques here today, We will be coming back for the 2d part of this, where nosotros volition deal with some commands like UCS, Wedlock, Decrease, INTERSECT and show you lot how to assemble the whole to create our last design.
