dimensioning a 3d model to 2d drawing autocad

Nosotros accept taken a good fourth dimension lately working on mastering the basics in AutoCAD, and with this skill, you must exist able to replicate any 2D images using AutoCAD.

As y'all must take noticed from our past experience, learning AutoCAD goes outset with understanding what the environment is fabricated of, How to draw basic shapes, and finally how to combine all the basics to create complex designs.

AutoCAD 3D features

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

AutoCAD is primarily for generating 2d sketches. It does take some ability to visualize those 2d sketches in 3d, and fifty-fifty to make 3d objects, but information technology'south primarily congenital around a flat, sketch-based workflow. If your invention is fundamentally 2-dimensional, or made of trivially interlocking 2d parts, AutoCAD might exist the right affair.

Inventor is for 3d product pattern. It'south a professional piece of software and takes quite a bit of fourth dimension to learn, but that'southward likewise true of its directly competitors. Information technology's currently Autodesk'south nearly powerful tool for mechanical blueprint. I can't give you lot a coherent feature comparison to SolidWorks or Creo because I don't know them well enough; I do know that SolidWorks is more popular. Inventor is 2nd, I think.

We practice have a fairly new product called Fusion 360. Information technology's congenital on the same modeling kernel as Inventor, and has better gratuitous form modeling. It's designed to exist an all-in-i package for product design by hobbyists and pocket-sized businesses. We focused on making the user interface as easy to learn as possible. It's still quite a new product, and gets updates every few months, partly based on user feedback from its forum. A major reward is that information technology's free until y'all showtime making coin with it, and fifty-fifty later that it's pretty inexpensive.

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

Surface Modeling and Solid Modeling

While talking about AutoCAD Drawing and CAD, information technology is important to know the deviation between Surface Modeling and Solid Modeling.

Surface modeling CAD (Blender, Sketchup, Rhino, Maya) deals with manipulating the curves and surfaces of a model. It's more free form and generally done by clicking and dragging the surface/curves effectually to your liking. It's ideal for architects, jewelry design, or annihilation you desire done aesthetically.

Solid modeling CAD (Solidworks, Inventor, ProE, SolidEdge, GeoMagic) deals with adding dimensions and constraints to a 3d model. It is "parametric" meaning you lot can define the shape and afterward edit. This is very essential for engineers since design changes are e'er happening. Great for mechanical parts that require constant iterations. Some solid modeling CAD can perform surface modeling but it's a nightmare.

AutoCAD 3D modeling 101

The following epitome shows you an overview of what the object is made up of.

All objects are arranged like this

The elbow:

Creating basic 3D AutoCAD drawing

Before fully diving into this, you should make certain all tabs are activated. (Right-click to show the menu)

Creating a Cylinder

To create a cylinder

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

Other routes y'all can use to create a cylinder are the post-obit.

Using the EXTRUDE command

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

To do that

1. Create a circumvolve the way nosotros learned
2. Type EXTRUDE and press ENTER
3. Select the circle and printing ENTER
4. Specify the height of extrusion

Using the REVOLVE command

1. Create a rectangle
2. Utilize the Circumduct command to obtain the cylinder

To practice that

1. Create a rectangle using the RECTANGLE command
2. Blazon Revolve and Printing ENTER
3. Select the rectangle and Press ENTER
4. Select one of the ends of the red line shown on the epitome above
5. Select the second stop
6. and press ENTER

Using this method, you tin at the final step decide not to close the cylinder, meaning you will have to enter an angle value less than 360 before 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 it. (use the POLYLINE command to create the rectangle). You can as well use the WEDGE command to create it.

Nosotros take pretty much created all bones 3D objects nosotros demand, now we need to create copies, rotate them and get together everything.

We have seen quite a number of new techniques here today, We volition be coming dorsum for the second part of this, where we volition deal with some commands like UCS, Union, SUBTRACT, INTERSECT and evidence you how to assemble the whole to create our terminal blueprint.
