3d Solid Modeling
3d Solid modeling is an extension of the surface model that allows the description of a volume through additional design rules. Solid models are created in a virtual space. Such an object (= solid) has a closed shell, which allows the clear definition of inside and outside. This makes it possible to check collisions between objects. The volume can be modeled directly or indirectly.
Direct representations construct the volume of simple primitives. Indirectly, the volume is described by its shell. Furthermore, properties can be assigned to the solid modeling. This expands the volume model to the product model. For example, by assigning a density, the mass of the body can be calculated dynamically, depending on the volume.
A dynamic sketching tool enables the rapid design of components, with parameters and dependencies being able to be assigned at any time during production. Solid Modeling is a prerequisite for the Module Features Modeling and Freeform Modeling.
Advantages of solid modeling
Complete, consistent and accurate description of the body shape
Source of information for downstream functions (including geometric calculations)
Automatic pattern generation
Good visualization capabilities (automatic hidden hide shading, shading)
Body collision considerations possible
Significantly less input to model complex objects than 3D Wire and surface models.
