Open issues:


============================================================================
- UI gtk2 to gtk4
============================================================================
  - gcad3d is using legacy-OpenGL 1.2 (displaylist-support).
  - Gtk3-port exist,but does not support displaylists.
  - all calls to gtk are concentrated in toolkit (src/gui_gtk2/*.c)



============================================================================
- Boolean operations with surfaces 
============================================================================
  - consistency checks of surface-boundaries (body-net)       -
  - boolean operations with surfaces                          -
  - boolean operations with planar surfaces                   90 %
  - trimmed polygonal_representation_of_curve                 OK


============================================================================
- Translate messagefiles
============================================================================
  - Existing languages: 
  - es fr it to be updated, new languages ..
  - eg with translate-shell "trans -b de:es \"text to translate ..\""


============================================================================
 offset-surfaces                                         -
============================================================================



============================================================================
- Add rounding surfaces
============================================================================
  - circular surface along spine                              -
  - intersection surfaces                                     OK



============================================================================
- interactive editor - modify object:
============================================================================
    - display objects not affected dimmed,
    - update all child-objects dynamic.
    - "edit object" in MAN and CAD shall display all objects following dimmed.
Example:

P20=P(20 0 0)
C20=P20 50
A20=C20
L20=P20 P(100 0 0)

Edit obj C20 (eg change radius 50)
- P20 - displayed normal;
- C20 - hilited; active obj to be modified,
- A20 - dimmed; following the obj C20 and child of C20
- L20 - dimmed; following, not child of C20.

- exit modifications with OK:
  - update all child-objects of modified obj C20 (A20)
  - change display of all objects following obj C20 from dimmed to to normal



============================================================================
- interactive editor - insert object:
============================================================================

only in mode MODIFY:
- provide button INSERT mit info "insert obj before active obj"
- activate INSERT: display text "ADD / INSERT" (replacing MODIFY);
  - active mode CAD/add; after OK back into MODIFY;


- Funcs:
  - insert new CAD-code into line before active modify-line;
  - display new created obj




============================================================================
============================================================================
- Project and Mirror currently only for individual objects,
  not for CCV (currently Translate only).

- mirror CCV (S#=MIR S# L#)

- update interactive editor to modify B-splines. 

- Search/Name ObjList objID edit - does not find and edit obj eg P24 ..

- Transformation of 3D Text: currently is always set in the XY plane.

- NC machining is graphically not yet active in the transformed reference system.

- NC-function are not yet completely implemented for alternative construction-planes

- Function for interactive positioning of sub-models to a contact position.

- Drawing 2D from 3D 

- With hatching, no islands are possible yet

- The programming interfaces are only partially documented.

- Step-Export only partially implemented

- Perspective view (only parallel view)
