Basic information about the C3D Labs' development toolkit and the new version of its C3D modeling kernel V16, as well as some examples of existing licensing programs, and current software developed on C3D.

1. One Toolkit for Developers!
Three Dimensions to CAD

2. What is C3D

3. C3D is a geometric modeling kernel (solid modeling kernel)
that incorporates all three crucial CAD modules:
●
3D modeling
●
3D constraint solving
●
3D file conversions
C3D Kernel

4. Used in software products as the component responsible for
geometric model construction and constructed model control
C3D Kernel
r1(u1,v1) = p + u1ix + v1iy;
r2(u2,v2) = p + u2iy + v2iz;
r3(u3,v3) = p + u3ix + v3iz;
r4(u4,v4) = p + u4ix + v4iy + z iz;
r5(u5,v5) = p + u5iy + v5iz + x ix;
r6(u6,v6) = p + u6ix + v6iz + y iy;

23. What's New in C3D V16?

24. The latest release of C3D
features more than 100 improvements
to the kernel's functionality
24

25. C3D Modeler

26. Transformation of Solids
with a specified grid
26

27. with a set of matrix:
Rotation, Mapping, Reflection, Scaling, Projection
27
Transformation of Solids

28. with a set of matrix:
Rotation, Mapping, Reflection, Scaling, Projection
28
Transformation of Solids

29. Swept Operations
One pair generatrix/directrix can be used
to build a series of independent solids
29

30. Cutting Threads
Adjusted according to the initial position and length
of the hole in which it is rendered
30

31. Shell Rings
with irregular faces is performed using
the constant bend radius
31

32. Conical Polygons
Through sheet metal bends is performed
through segmentation of the support arches
32

33. Sheet Metal Bodies
with different lengths to the left and to the right
of the bending extension
33

34. Sheet Metal Bodies
34
The closure of angles is rendered through
the rotary processing of the target area

35. Filleting Edges
35
Created more efficiently, with dramatically fewer inaccuracies
and with no building limitations

36. Thickness of Surfaces
Based on singular (polar) points
36

37. Reinforcing Ribs
Composed of some planar and revolution surfaces
37

38. Binding Surfaces
The tangent line junctions of surfaces built from
a web of curves are rendered more smoothly
38

39. Boolean Operations
Have been significantly improved for 2D objects
39

40. Time of creating sections and cuts
Have been greatly reduced due to use in C3D:
→ a complex optimization of creating processes
→ efficient parallel calculations within the kernel
40

41. Stitching Multiple Surfaces
in the multithreading mode with a high level
of securing threads from unauthorized intrusion
41

42. C3D Solver

43. Optimization of Multithreading
using Intel C++ Studio

44. Journaling in 2D Solver
Provides the calling history of API functions
→ Recorded automatically to file
→ Saved in editable format *.jrn
→ Allows remote debugging of bugs that are
reported by customers
44
The automatic regression test system in C3D Solver
is being implemented through the journaling databases

45. 3D Assemblies

48. Parameterized Splines
Passing through the interpolated points
+ more clear behavior of these splines when
any type of constraints are specified
48

49. Parameterized Splines
Through its points with fixed coordinates,
and through vectors of the 1st, 2nd, and 3rd derivatives
at points with the specified parameters
49

50. What's more?
C3D Solver adds a new geometric object called the “Cluster”.
Clustering is useful for arranging geometric models against a
hierarchy of nested sub-assemblies. Designers can employ the same
solver instance for an entire assembly This saves computing→
resources and speeds up calculations when modifying 3D models
A new function for manipulating drawings and sketches
by the push-pull method has been updated – DRAGGING
→ the shape of objects changes preserving constraints,
in real time
→ more interactivity in all applications on C3D
→ dragging of the objects that are directly or indirectly
related with splines by constraints
50

name, designation, owner
Adjusts the accuracy of exported STL by three parameters:
→ the maximum deflection
→ the maximum pivot angle of a normal curve or surface
→ the maximum length of a triangle side
