Getting a Simple Animation of Your View

The last 3D Orbit option you’ll learn about is one that is perhaps more fun than practical. You can get a simple animated view of your model that rotates your view about the target point. Try this exercise to see how it works. 1; To make this animation a bit more interesting, turn on the Go around…

Viewing Your Model in Perspective

So far, your views of 3D drawings have been in parallel projection. This means that parallel lines appear parallel on your screen. Although this type of view is helpful while constructing your drawing, you will want to view your drawing in true perspective from time to time, to get a better feel for what your 3D model actually looks…

Moving Objects in 3D Space

AutoCAD provides two tools for moving objects in 3D space: Align and 3D Rotate. Both of these commands are found on the Rotate fly out of the Modify toolbar, They help you perform some of the more common moves associated with 3D editing. Aligning Objects in 3D Space In mechanical drawing, you often create the parts in…

Editing a Mesh

Once you’ve created a mesh surface with either the Edge Surface or Revolved Since tool, you can make modifications to it. For example, suppose you want to add a spout to the pitcher you created in the previous exercise. You can use grip” to adjust the individual points on the mesh to reshape the object. Here, you might…

Other Surface-Drawing Tools

In the last example, you used the Edge Surface tool to create a 3D surface. There are several other 3D surface commands available that allow you to generate complex surface shapes easily. Using Two Objects to Define a Surface The Ruled Surface tool on the Surfaces toolbar draws a surface between two 2D objects, such as a line…

Adjusting the Settings That Control Meshes

As you can see, the seat in our butterfly chair is made up of rectangular segments. If you want to increase the number of segments in the mesh,you can change the Surftab1 and Surftab2 system variables. Surftab1 controls the number of segments along edge 1, the first edge you pick in the sequence; and Surftab2 controls the number…

Creating a Curved 3D Surface

Next, you will draw the seat of the chair. The seat of a butterfly chair is usually made of-canvas and drapes’ from the four corners of the chair legs. You will first define the perimeter of the seat using arcs, and then use the Edge Surface tool on the Surfaces toolbar to form the shape of the draped…

Creating Complex 3D Surfaces

In the previous example, you drew a chair composed of objects that were mostly straight lines or curves with a thickness. All the forms in that chair were defined in planes perpendicular to each other. For a 3D model such as this, you can get by using the Orthographic UCSs. At times, however, you will want to draw…

Using Advanced 3D Features

AutCAD’s extended set of tools for working with 3D drawings lets you create 3D objects with few limitations on shape ‘and orientation. This chapter focuses on the use of these tools, which help you easily generate 3D forms and view them in both the Perspective and Orthogonal modes. Mastering the User Coordinate System The User Coordinate System…
