Point 9: Surface Modeling in AutoCAD 2002
Deepak Maini
Surface models are a type of three-dimensional (3-D) models with no thickness and are hollow from inside. They are used in the automobile industry to create the body of a vehicle, as well as in the aerospace and plastics industries. The various methods to create surface models in AutoCAD are:
-
Converting a wireframe model into a surface model
-
Creating surfaces using two dimensional (2-D) elements
-
Using standard surface primitives
This ReferencePoint discusses the methods to create surface models. It also explains how to suppress the hidden edges in the surface models and edit the surface models.
Converting a Wireframe Model into a Surface Model
The 3DFace and Pface commands help convert a wireframe model into a surface model.
| Note | To learn more about the wireframe models, see the User Coordinate System ReferencePoint. |
Creating Surfaces Using the 3DFace Command
Use the 3DFace command to create 3-D faces using the vertices of a wireframe model. To invoke this command, select Draw->Surfaces->3DFace from the menu bar.
When this command is invoked, a prompt ensues to specify the first, second, third, and fourth points of the 3-D face to be created. After the fourth point is entered, a prompt again asks to enter the third and the fourth points. If the third and the fourth points are specified, then AutoCAD creates the second face by assuming the previous third and fourth points as the first and second points, respectively. This prompt will continue until you press Enter.
Each pair of points you...
