MegaCAD 3D is the ideal synthesis of an innovative solid and
surface modelling 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.
