Solid modeling is the process of making 3D objects by defining their shape, surface, and volume. It starts with basic 2D and 3D shapes. Simple flat shapes like lines, circles, rectangles, polygons, and arcs are used as outlines that can be stretched or rotated into 3D forms. Basic solid shapes like cubes, spheres, cylinders, cones, and rings can be combined or changed using Boolean operations to make complex models. Using both 2D and 3D shapes helps designers quickly create detailed and usable models, common in engineering, architecture, and product design.

The primary functions for creating 2D objects and detailed instructions on how to effectively use them in various design projects.

Building of geometric objects such as POINT, LINE, and CIRCLE (with several methods of creation), ARC (also created in multiple ways), SPLINE, and CONTOUR within the three-dimensional space. These elements form the foundational components for complex 3D modeling and design processes.
Checking carefully if the objects are properly closed, whether they are self-intersecting, and if they all lie precisely on the same line or within the same plane.
Obtaining the coordinates of a specific point by using the parameter of the object path, which ranges from 0 at the start to 1 at the end.
The feature that enables you to obtain an array of line segments within the wireframe object view, providing a clear representation of the object's structural lines.
Algorithms for exploring the positional relationship between two objects allow you to determine various spatial configurations. For example, you can verify whether the objects lie on the same plane, assess if one object is positioned entirely inside the other (in the case of closed objects), or identify if the objects intersect each other in any way. These techniques are fundamental in understanding how objects relate to each other in space.

Making 3D objects uses methods like modeling, sculpting, and procedural generation. Learning these skills helps improve how they work and look.

Building of various geometric objects such as BOX, SPHERE, CYLINDER, CONE, TORUS, ELLIPSOID, and SPHERIC BAND. These fundamental shapes serve as the building blocks for more complex designs and structures in three-dimensional modeling.
Obtaining the arrays of vertexes, edges, triangles, and normals from any 3D object for further processing or analysis.
Calculating the UV texture coordinates for each polygon vertex involves using various methods such as cubic, spherical, and cylindrical techniques for texture mapping. These approaches enable precise placement of textures on 3D models, enhancing their visual realism and detail.
Assigning specific materials and textures to objects.

Creation of Surfaces and Solids

Advanced tools designed to turn 2D objects into detailed and precise 3D models. This improves the design’s depth, accuracy, and appearance, making the final result clearer and more refined.

Kinematic Operations

Kinematic operations involve the process of generating new objects by extruding a two-dimensional shape along a defined path within three-dimensional space. This technique is fundamental in modeling, allowing the transformation of flat designs into complex 3D forms through guided movement.

Solid modeling creates 3D objects by shaping form, surface, and volume. It starts with 2D shapes like lines and circles, which become 3D forms. Basic 3D shapes like cubes and spheres combine or change to build complex models, aiding design in engineering, architecture, and products.

Boolean Operations

Boolean operations in solid modeling combine simple solids using union, intersection, and difference. They enable quick, accurate CAD modeling, aiding prototyping, analysis, and manufacturing, and enhance software flexibility for detailed shapes.

Solid Modeling

Solid modeling is a CAD technique that creates precise 3D object shapes, defining volume and surface. It enables detailed design review, stress tests, movement analysis, and manufacturing planning, speeding up product design with fewer errors and improved collaboration.

Direct UI Experiment

Traditionally, Windows applications are built upon the GDI/User windowing hierarchy, and thus restricted in several areas. While you can certainly generate a nice application quickly with the built-in control-set and get a standard clean look, you will soon enough stumble upon the limitations of the Windows controls - especially if you want to build something that looks a little more flashy.

Visual Studio Experiment

Visual Studio is an integrated development environment (IDE) from Microsoft. The Visual Studio IDE is a creative launching pad that you can use to edit, debug, and build code, and then publish an app.
