Tip    In order to easily draw a polyface mesh with PFACE, draw 2D objects as a guide for


picking vertices. Then you can use object snaps to pick the vertices. Also, for poly* face meshes on more than one plane, draw a diagram that numbers the vertices. This helps you specify which vertices make up which face.


During the second phase of the prompts, when PFACE asks you to define the faces, you can right-click and choose Layer or Color and specify the layer or color. Then specify the vertices that are to be on that layer or color.


In the following Step-by-Step exercise, you draw a hexagonal night table with polyface meshes.


The drawing used in the following Step-by-Step exercise on drawing polyface meshes, ab23-b.dwg, is in the Drawings folder of the AutoCAD 2002 Bible CD-ROM.

Step-by-Step: Drawing Polyface Meshes


1.    Open ab23-b.dwg from the CD-ROM.



3. Type pface J. Follow the prompts. First you specify all the vertices. Then you specify the top hexagon, then the five sides (the front is open), and finally the bottom hexagon. Unfortunately, if you make a mistake, you must start over.
