Simple geometric modeling concepts of sophisticated engineering design
Part 4 of 8
04 Surfacing
Surfacing is the definition of the exterior area of the solid body in terms of color, texture and even lights, shadow and environmental background.
The texture of a solid body can be assigned from the library of pre-defined industrial materials such as wood, metal, concrete, glass and even water.
Aside from the appearance point of view, surfacing can also be seen in terms of modeling elaborately shaped solid bodies. Complex solid components, especially those with wavy surfaces, are often formed using what else, surfacing tools! A surface is a plane which may also be a wavy plane that can be extruded into the three dimensional space to form a more complex body, through the union with other wavy surfaces. On its own, a surface has only two dimensions (length and width), without a thickness. However, surfaces can be joined together to form solid bodies.

Part 3 of 8
When a certain shape is given explicit dimensional values, it is said to be fully defined. As such, a sketch turns black from blue and it cannot be moved or deformed in that state.
Sizing is basically specifying length and radius of a sketch. The elements in a sketch can be given dimensional relationships (equal, parallel, perpendicular, tangent, coincident, pierce, colinear) with each other to fix their size and position in space.
Dimensional variables can also be defined and assigned to sketch elements. This is called parametric modeling in SolidWorks where dimensions are given in a table of equations.
Zooming in or out to magnify details or expand the viewing horizon is also an available feature in geometric modeling software to establish size and context.
The sizing feature of geometric modeling extends to the determination of mass properties of a solid body by simply drawing it. Once drawn, the area, volume, centroid, and moments of inertia can be subsequently inferred using the evaluation tool. When the material is assigned to the solid body, the mass can also be determined instantaneously.
For curved edges and surfaces, a measuring tool can find automatically the intersection points.

My recent project: Shelter on a Hill. It is a photo anthology of huts that I passed by on my mountain hikes.
