Progress of a opencascade sketch implemenation.

~/opt/hal-core/src/hal/components/matrix/cpp_interface/libocct/occ_apps/OcctQtWidget

You need to load (eventually compile) the 2 projects of above path.

  • OcctQtApp (is only the executable app that executes the OcctQtLib code)
  • OcctQtLib (the source code. Coded as a Widget)
    The opencascade.tar.gz is the used opencascade library. The .pro files have linked path's to this.
    This opencascade archive is also a qt project. And can be compiled by qt.
    Sniff into the ~/opt/opencascade/oce-upstream-V7_5_0beta/adm/qmake/ dir to find the Occt.pro file.

Specs until now

  • User can select 3 types off drawing grid plane's to draw on.
  • Primitives all in 3d space working : point line linestrip arc 3p center arc 3p contour circle 2p center square
  • Most of the icons work, like view top, bottom, left, right etc, zooming, etc.
  • Color selector. Contains a nice piece of code to convert qt to occt colors.
  • For F8 ortho i made a test input that run's like a classic autocad line input method.
  • Contains a old russian code named libsctecher for reference.

Todo soon

  • 3d spline... Got algo for this already.
  • bezier curve... Got old algo for this, but maybe use a occt shape for this.
  • Starting a trim implemenation.

sketcher

For reference : eryar/occSketcher#4 source code example.
