Autocad 3d models

by Design Workshop Sydney

In common with all modeling programs there are three types of Autocad 3d models: these are wireframe models, surface models and solid models. We look at all three types in  our Autocad 3d course.autocad-3d-models
The first and earliest type of 3d model is the wireframe model and first appeared in the public arena in late-1970s video games. Wireframe models (top left) lack faces and are like  models made from coat-hanger wire. To create the model 2D objects  like lines, circles and arcs are used. You can still orbit around the model and apply colours to the lines, but they are limited in their uses and are in themselves not used much these days.
The next type of 3d model in Autocad is the surface model (bottom left). These are similar to wireframe models but are created from faces. They resemble objects made from cardboard, like boxes, spheres and cones. They are not true solids in that if you dissect a surface model you can see the hollow interior space. Again, they are not used so much these days.
The third type of 3d model is the solid model (bottom right). Again these can be constructed from boxes, spheres and cones, but like objects in the real world solid models can be joined and dissected, revealing cross-sections of solid interiors.
Solid modeling is the most used of the three types, and is versatile in simulating objects in the real world. In Autocad’s 3d modeling toolset there are many ways of creating 3d models – from simple geometrical shapes, to extruding and lofting profiles around paths. You can unite and subtract models, and you can create organic meshes for terrain or non-geometric masses.
Solid models also respond well to the application of realistic materials and photometric lighting systems which simulate the way objects and surfaces behave in the real world. As such 3d modeling is used in a variety of visualization contexts, from engineering to architectural and interior design.
The 3d interface in Autocad is user-friendly and easy to learn, and we take time to teach a broad range of applications in our classes including modeling, materials, lighting and animation. See many examples of our clients’ work on our Facebook page.
