What is C3D

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

Used in software products as the component responsible for geometric model construction and constructed model control

C3D Kernelr1(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;

What's New in C3D V16?

The latest release of C3D features more than 100 improvements

to the kernel's functionality

24

C3D Modeler

Transformation of Solids

with a specified grid

26

with a set of matrix: Rotation, Mapping, Reflection, Scaling, Projection

27


with a set of matrix: Rotation, Mapping, Reflection, Scaling, Projection

28


Swept Operations

One pair generatrix/directrix can be used to build a series of independent solids

29

Cutting Threads

Adjusted according to the initial position and length of the hole in which it is rendered

30

Shell Rings

with irregular faces is performed using the constant bend radius

31

Conical Polygons

Through sheet metal bends is performed through segmentation of the support arches

32

Sheet Metal Bodies

with different lengths to the left and to the right of the bending extension

33

Sheet Metal Bodies

34

The closure of angles is rendered through the rotary processing of the target area

Filleting Edges

35

Created more efficiently, with dramatically fewer inaccuracies and with no building limitations

Thickness of Surfaces

Based on singular (polar) points

36

Reinforcing Ribs

Composed of some planar and revolution surfaces

37

Binding Surfaces

The tangent line junctions of surfaces built from a web of curves are rendered more smoothly

38

Boolean Operations

Have been significantly improved for 2D objects

39

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

Stitching Multiple Surfaces

in the multithreading mode with a high level of securing threads from unauthorized intrusion

41

C3D Solver

Optimization of Multithreading

using Intel C++ Studio

43

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 Solveris being implemented through the journaling databases

3D Assemblies

with reflection symmetry of some objects

45

3D Assemblies

with reflection symmetry of some objects by curves on pairs of bodies

46

3D Assemblies

with reflection symmetry of some objects by external facets on pairs of bodies

47

Parameterized Splines

Passing through the interpolated points+ more clear behavior of these splines when

any type of constraints are specified

48

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

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

C3D Converter

Import Parasolid и STEP

52

Improved multi-threading converts data faster → for Parasolid – 1.6x faster → for STEP – 1.9 faster

Intel i5 with 4 Cores

Import STL и VRML

53

Supports polygon modelsExample: 2 378 154 points and 792 718 triangles

New C3D Converter

Passes attributes of items during conversion: 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
