CATIA V5 3D Solid Modelling
CATIA V5´s greatest improvement over V4 could probably said to be in creation and handling of Parametric Solid bodies. Using functions like `Offset´ and `CloseSurface´, surface `CloseSurface´, surface entities may also be seemlessly integrated into Solid-Based Design work, work, as our completed `button´ demonstration shows below.

CATIA V5 3D Solid Modelling
To complete our button, we will need the trimmed surface entities that were created in the previous demonstration. You may also swap between show/no show to select the needed trimmed faces and leave l eave any undesired parent entities(i.e. shetches) hidden. As the side faces of our botton were extruded from a planar rectangular profile, the bottom of our hollow `quilt´ should be planar. Planar openings in collective face quilts can be filled, and the resulting closed body automaticaly upgraded to a solid, using the `close surface´ function. 1. Select the quilt entity and choose the `Close Surface´ function. Our Solid should be now created problem-free. 2. Since our Button may not have any hard edges on the `visible side´, a Fillet radius radius should be applied. Caution is advised when selecting the desired radius measurement of our fillet. Some branches of design engineering must obey certian NORM standards dictating the minimum radius of a fillet that will come in contact with the end user (or the OEM customer may have a corresponding in-house standard). We must also plan our model: our next and final step will to refine our solid body to a thin-wall housing Shell,, so we want to provide a Shell radius definition greater than the thickness of our proceeding inward Shell Shell thickness. NOTE: If the Shell is to be outwards, this concern is then irrelevant. We will enter a Fillet radius of 2.5mm. 3. In the final step of this demonstration, we will `Shell´ our button, that is, reduce or rounded block to a hollow, thinwall part with an open bottom.
