The method of drawing three-dimensional graphics with CAD;
1.3D modeling tool:
CAD software usually provides a series of 3D modeling tools, such as stretching, rotating, lofting and chamfering, which can help users create and edit 3D shapes.
Users can create geometric bodies with different shapes by setting parameters and operating controls, such as cubes, cylinders, spheres, etc. And then create a more complex 3D model by combining and modifying these basic geometries.
2. Multi-view display:
CAD software supports observing and editing 3D models from different angles, and users can easily rotate, translate and scale the models in different views for better observation and editing.
Usually CAD software provides orthogonal views (front view, side view, top view, etc.). ) and perspective view can help users understand all aspects of the model more comprehensively.
3. Materials and textures:
CAD software also supports adding materials and textures to increase the realism of 3D models. Users can add different colors, materials and textures to the model surface to make it closer to the appearance of real objects.
4. Rendering function:
Many CAD softwares have rendering functions, which can simulate the lighting, shadows and material effects of 3D models and generate more realistic images. This enables users to generate high-quality rendered images for display and demonstration.
5. File format and output:
CAD software usually supports various file formats and can export 3D models, such as STL, STEP, IGES, etc. These formats can be shared and used in different software and platforms.
Generally speaking, CAD software has powerful 3D modeling and editing functions, which can help users create, edit and visualize various complex 3D graphics and models. The three-dimensional design function of CAD is not only widely used in engineering, architecture and other industries, but also plays an important role in manufacturing, art design, virtual reality and other fields.
