MegaCAD 3D is the ideal synthesis of an innovative solid and surface modeling system and a full-feature 2D drafting program. If you are developing your model in 3D or if you are drawing a 2D design, each step will automatically be transferred from one dimension into the other one.
In MegaCAD 3D, the user has a powerful solid modeling system. In addition, any designs can be wholly or partly implemented in the surface modeler. Because they share a common data structure, the two forms of model can be combined. This makes it possible, for example, to trim a solid object with a complex free-form surface, to give the solid a new shape. Conversely, the surface of a solid body can be isolated as a separate surface.
