Choose Pan. Pan to a new area of the drawing. Choose Constrained Orbit to set the mode back to orbit. Choose Perspective. Perspective view displays objects in perspective so that all parallel lines converge at one point.
Objects appear to recede into the distance, and parts of the objects appear larger and closer to you. The shapes are some what distorted when the object is very close. This view correlates more closely to what your eye sees. Parallel view displays objects so that two parallel lines in a drawing never con verge at a single point.
The shapes in your drawing always remain the same and do not appear distorted when they are closer. Choose Visual Styles from the pop-up menu. Choose Visual Aids from the pop-up menu. Choose Preset Views from the pop-up menu. Choose one of the following standard 3D views. Choose View, Orbit, Free Orbit. The 3D Orbit Arcball appears.

Choose Tools, Palettes, Dashboard. There are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object. Because each object that makes up a wireframe model must be independently drawn and positioned, this type of modeling can be the most time-consuming.
The AutoCAD surface modeler defines faceted surfaces using a polygonal mesh. Because the faces of the mesh are planar, the mesh can only approximate curved surfaces. With the AutoCAD solid modeler, you can make 3D objects by creating basic 3D shapes: boxes, cones, cylinders, spheres, wedges, and tori do- nuts.
You can then combine these shapes to create more complex solids by joining or subtracting them or finding their intersecting over- lapping volume. You can also create solids by sweeping a 2D object along a path or revolving it about an axis. You can specify different Z coordinates for each corner point of a 3D face. Entering i or invisible before the first point of an edge makes the edge invisible.
Type EDGE at the command prompt. Type Revsurf at the command prompt. Type Surftab1 at the command prompt. Type Surftab2 at the command prompt.
Choose Draw, Modeling, and one of the following solid primitives. A polysolid can have curved segments, but the profile is always rectangular by default.

Choose Draw, Modeling, Revolve. Open a drawing with 2D objects to sweep and display in a 3D view. Choose Draw, Modeling, Sweep. Choose Draw, Modeling, Loft.
Type LOFT at the command prompt. The only thing stopping me going for the 3 or 3. BTW if it helps the rated gain on the 2. Or should I spend the extra money on a 3 or 3. Thanks in advance to any help with this decision. Last edited by vk2amv; at PM. I have a 2. The only thing that you have to remember is the bigger the dish, the more securely mounted it has to be, either on the ground or attatched to a building.
If trying to get the weak signals then there are times where the bigger dish is better. Are you going to go for feeds on those weaker birds or just stick to the mainstream channels.
But as others have said the bigger the dish the more wind drag etc. Weigh up the costs against what you want from it. Rain fade is not such an issue on Cband, its Ku band that's effected by rain. Its possible to build a bracket next to your feed horn to hold a offset Ku LNB with a hose clamp and operate with a switch or to just buy a dual c and ku band LNB to save you all the mucking around.
I'll just echo some of the other comments, I got a 3. As you said "there is very little of interest to me on KU Band other than Optus D1 and D2" then I'd recommend you have a separate small Ku dish for those sats and a dedicated mesh dish for C-Band. This will give you superior results for both bands as you are avoiding signal loss by not trying to compromise a single dish with two different bands.
It's like using combi terrestrial antennas. A combi can work fine, if the signals are strong, but separate antennas will perform much better with marginal signals. As others have mentioned In very-low signal instances, it can be the difference between sufficient signal quality to lock onto those signals, or no reception at all on those very weak ones.
Based on the advice here I have decided to go for a 2.
