This is a tutorial for drawing an EDGESURF polygon mesh of a tunnel it may be used to draw a computer mouse or sismilar product, with bit of tweaking.

Many AutoCAD commands that you use to edit 2D objects work on 3D objects as well, some with special options for 3D. In this article I discuss how the familiar 2D editing commands work on 3D objects.

What happens when you use 2D commands on 3D objects? Ellen Finkelstein says you may be surprised. Simple commands such as COPY and MOVE are intuitive enough, but have you ever used EXPLODE on a curved body?

Thickness is an object property that gives the object a 3D effect. If you apply thickness to lines, circles, ellipses, arcs, polylines, solid fills, and traces they will acquire some height. Thus by changing the shade mode they will look like 3D surfaces and/or solids. Elevation is the default distance from XY plane along Z axis. Although you can override this value with direct coordinate entry or by using OSnaps it might be useful. The current tutorial shows you how to draw a simple 3D table with the help of elevation and thickness.

Viewports enable you to view the models from different view points at the same time. Various display settings such as zoom factor and shade modes can be applied to every viewport. There are two types of viewports available in AutoCAD: Tiled and Floating. Tiled viewports are applicable to Model space while Floating viewports are used in Paper space only. Note: The tutorial is designed for AutoCAD 2004 though might be applicable for other releases.

This tutorial is a quick review of different methods for viewing 3D models. Note: The tutorial is designed for AutoCAD 2004 though might be applicable for other releases.

This tutorial shows how to draw a simple archway such as in an architecture drawing utilising POLYLINE, EXTRUDE and REVOLVE.

Most of Wireframe models are built with 2D objects. The success key is in correct use of UCS and 2D commands. Here you will learn how to build the following simple Wireframe models. Two further tutorials will help you to create more complex Wireframe models.

The TRIM and EXTEND commands are not only used in 2D drawings but also applicable to Wireframe models. In this tutorial you will draw a 3D polyline and use TRIM and EXTEND in 3D space.

Every drawing is equipped with a coordinate system called WCS or rather World Coordinate System. The WCS is fixed and you cannot change its location or orientation. Instead the User Coordinate System or rather UCS is used. You can move or rotate UCS in any direction. The placement of objects is based on the current UCS so you can even use 2D commands to create objects in 3D space with various orientations.

Prior to AutoCAD 2002 I was able to plot an EPS file of a solid model and then import the EPS file into a new drawing to obtain a 2D drawing of my original 3D model. I can`t seem to do that with AutoCAD 2002. Does anyone know another way to accomplish this?

Wireframe models can be used in creating surfaces and solids. Here we will build the Wireframe model of a tent. In a later tutorial you will cover the tent with surfaces.
