Report bugs or proposals for improvements to support[at]gcad3d.org.

gCAD3D has its own

import and export-programs,
integrated 3D-OpenGL viewer,
program interpreter for geometry and NC commands in 3D,
programming interface for userprograms (plugins), NC-processors

The creation of geometrical elements / NC-programs can be done by -

interactive generated geometric objects or
manually generated commands or by the
import module (Step - Iges - dxf) or by the
Mockup import module (Vrml-1 - obj ..) or by loading a
datafile created by program or by
special importprocessors (user-programs)

The programinterpreter provides functions for -

creation and spatial visualisation of data
NC-work, direct and program controlled
preparation of data (building contours ..)
analysis of data
programming functions

Functions for making documentations:

Display of 2D-draftings, 3D-models and images (bitmaps) in the same 3D-model space
drafts and models can be generated / modified dynamically
all graphic objects can be connected with interactions

Interactions can:

call models (like HTML - HREF)
call programs (start plugins)
change the viewport
change model parameter (dimensions ..)

Outputting data is done by the -

DXF, IGES or STEP export module or the
standard ISO postprocessor
special export processors (user-programs)
native format APT3D

The programminginterface offers -

creation and analysis of geometric objects
interactive dialog functions (selections ..)
automatic compile, link and reload at runtime (DLL's in C)

Videos zu gCAD3D:

- create contours S24, S25 from curves;
- make offset-contours S26, S27

- create surface from polygon 1000 x 800, load image as texture
- take contours as B-splines, polygons from image
- modify the B-spline-points
- export contours in DXF-format.
