@ -49,12 +49,10 @@ o Advanced Transformations
|
|||
- Add statement for 2D and 3D minkowski sum
|
||||
- Add statement for refinement via surface subdivision
|
||||
- Add statement for intersections in cartesian product of childs
|
||||
- Add statement for mirroring objects (without inverting them)
|
||||
o Function-Module-Interface
|
||||
- Pass a module instanciation to a function (e.g. for a volume() function)
|
||||
- Pass a function to a module instanciation (e.g. for dynamic extrusion paths)
|
||||
o Language Frontend
|
||||
- Allow using the childs of a module instance inside the module
|
||||
- Allow local variables and functions everywhere (not only on module level)
|
||||
o DXF Import
|
||||
- Support for POLYLINE entity
