TUTORIAL 1

AutoCAD 2007 3D Modeling
Learning Objectives
After completing this tutorial, you will be able to:

• Use the new 3D Modeling tools in AutoCAD 2007. Required Competencies
Before starting this tutorial, you should have been able to:

• Use the 3D Modeling tools available in previous releases of AutoCAD • Use AutoCAD at an intermediate to advanced level • Manipulate the UCSThe new 3D modeling tools in AutoCAD 2007 allow you to model complex freeform  shapes that previously were not possible to model in AutoCAD.  This tutorial assumes  that the user is completely familiar with creating precise 2D sketches of arcs, lines,  polylines, and splines in any location as well as the 3D tools from previous releases.

1.The first thing I would do is turn off the grid.  In almost 20 years of doing CAD I  have not had anyone give me a convincing reason for using a grid except for a  few narrowly defined cases.  I consider the use of a grid the mark of an amateur.   Notice that there is a new tool in the tray marked DUCS.  The Dynamic User  Coordinate System will allow you to sketch on planar faces of solids without having to manually change the UCS.  I would also turn on the LWT lineweight and experiment with the Settings  display scale to get a thickness you can easily see.

3.In the upper right hand corner of the screen you will find the new Dashboard.

  4. If you move the mouse to the gray bar in each of the control panels a down  pointing chevron will appear that will reveal more tools if you click on it.

5. Right Mouse Button (RMB) click in one of the control panels of the Dashboard  and set the visibility of the control panels as shown.  Expand the 3D Make  control panel.  This will give you access to both the 2D Draw and the 3D Make  tools.

6.In the lower right corner of the screen you will find the Tool Pallets.  I prefer to  have the Modify tab selected.  (You should know how to customize the Tool  Pallets from previous releases.)  I prefer to have the tool description text turned  off and I have added a few tools that I use often, particularly Shell, which were  left off of the Dashboard.  Unfortunately, the Dashboard cannot be modified.

7. Openthe file named Tutorial 1. Turn off all layers except the Polysolid layer and make the Polysolid layer the active layer. I have set the delobj = 0 that all entities will be preserved. Set the Visual Style to Realistic. • Select the Polysolid tool and RMB Select Object and click on the wireframe sketch.

Undo and then experiment with different settings for Justify, Width, and Height. • • • Selectthe Polysolid tool and RMB Select Width, experiment with the settings. Select the Polysolid tool and RMB Select Height, experiment with the settings. Select the Polysolid tool and RMB select Justify, experiment with the settings.

  8. You should be able to figure out how to use these tools on your own.  Pyramid is  new.

9. Turn off all layers except the Extrude Surfaces layer and make it the active layer.   Select the Extrude tool and extrude the arc, polyline, spline and line as surfaces.   Surfaces in previous releases of AutoCAD were of limited value, but in  AutoCAD 2007 surfaces can be used to edit solids.
