Being a great 3D CAD designer requires time, and an understanding of how to manipulate commands at your disposal within the CAD software. With some of my own trading secrets I can help you design 3D models in less than half the time that most CAD designers take. With these tips, and a good understanding of CAD software commands, your designs can be professional, accurate, and developed within minutes. However, do not forget, accuracy, and accuracy are more important in designing than speed.
When a 3D model begins the most important trick is to begin designing the right point. In most CAD programs there is now space within the 3D kingdom called the source. The source is the point where drawing planes within the model space is intersecting. The three planes are known as XY, XZ, and YZ airplanes. Ideally the center where all they meet is the source of the 3D environment, and where any professional designer should start first. The advantage of doing this allows you to draw a sketch in any of your directions, making the process of using commands easier. Not only are the airplanes used to sketch, but they can be used in conjunction with commands to perform the necessary tasks to create 3D models.
Before any CAD designers start drawing 3D they need to ask themselves what is the most efficient way to design this model. Why a good CAD drafter is his way, or he goes about designing the project. The smallest amount of commands is better. Always try to think about how you can use commands like mirrors, and copy them to reduce the amount of work in the design. For example, if a drawing is exactly the same from some point center, you only need to draw half of it, then use the mirror to create the other half. Ideally CAD designers will design half from the emission source, so the edge of the mirror depends on an airplane. This will allow the order to be executed properly, as well as the design center of the origin, exactly where you want it.
With years of experience designing 3D models with CAD, I've learned that keeping your design centered at the source is the most important decision you can make. While your environment for creating 3D source features allows you to have a round axis for commands like revolve, and circular patterns. If you are extruding something lying in the XY plane for example, there is an inside option urgently allowing the thing to be urgent in the same direction, placing your 3D object directly in the center of the source. If you take advantage of all the commands embedded in CAD programs you can save minutes, hours, and even day work values.
The secret to being a great 3D CAD designer is to utilize all the tools available, and to design your features with the least amount of steps. Make sure you spend a few minutes before each design that studies the characteristics and dimensions that make up the 3D model. After practicing techniques over time, you should identify the most direct path to achieving your 3D drawing. Also make sure you are familiar with all CAD software instructions, because if you do not know the strength in your hands, how can you benefit from it?
