It is like standing in one place and rotating your body around to view each side of a room Step Distance is the distance the camera and target move each time you use the Move keys on the speedbar or the arrow keys on the keyboard On a big drawing you might want to move in 5 foot or 10 foot increments If you re trying to position yourself in a vehicle for a view out the window you might set the step distance smaller say to 2 in order to make minor adjustments Step Angle is the number of degrees the view changes each time you use one of the rotate buttons on the speedbar or the rotate keyboard keys Chapter 1 Welcome Chapter 1 Welcome to The 3D Viewer This chapter introduces you to the new Diagram Program 3D Viewer It explains the basic ideas behind 3D program features and how to get help with the program if you need it In this Chapter e Introduction e Why 3D e Compatibility e System Requirements e Help Resources 1 1 1 2 Chapter 1 Welcome Why 3D Professionals from many different industries often use three dimensional diagrams to visualize scenes and to make presentations It helps them under stand how an object will appear from different angles If all you have are 2D sketches on paper visualizing a scene as it really looked can be difficult 3D gives you a new perspective on the simpler plan view drawings that you create in 2D It allows you to view your diagrams in a dynamic rather t

49. y switching back to the 2D plan diagram When you finish editing your diagram you open it in the 3D Viewer again This process can be repeated as many times as you like working back and forth between 2D and 3D until your 3D view is perfect Before You Start The 3D Viewer was created as an enhancement to Version 6 0 of The CAD Zone s Diagram Programs and is designed to run side by side with any of them It is opened and run from within the Diagram Program with just a simple mouse click Any 2D diagram already loaded on the drawing screen is automatically converted to 3D There is very little that you need to do to create a 3D model since most of the process is automated for you The 3D Viewer is meant to be used with diagrams created with Version 6 0 and above of any of the CAD Zone s diagram programs If your drawing was created with an earlier version or was imported from another CAD program you will need to edit the diagram before it will appear properly in a 3D view The older 2D objects such as symbols and line types will still appear in the 3D Viewer but as 2D images You need to manually replace these 2D objects with similar objects from Version 6 0 or above in order to have them dis played as 3D images If you have not done so you should upgrade to the newest release of the particular 2D diagram program that you are using This ensures that all of your diagrams will be fully 3D capable as you create them Upgrade pricing is av
