• Repair part: Heals a body by removing and repairing common geometry faults in an
attempt to create a valid solid.
• Simplify part representation: Simplifies a curve or a surface by using analytical and
more robust representations of the entities.
• Repair edges: Repairs inaccuracies in the edges of a sheet or a solid body by recalculating edge and vertex geometry to a specified precision wherever possible.
• Repair and sew faces: Repairs problems in the faces of the selected part then tries to
sew them into a solid or sheet part.
• Remove small features: Removes small features such as edges, faces, spikes and gashes
from the input parts.
A hole-filling tool has been included that allows a face to be reconstructed from its bounding
edges. This tool is often useful in cases where the face cannot be healed or is missing. A
new selection tool has been developed for selecting the smallest loop of laminar edges that
include the currently selected edges.
The CAD healing tools, including the hole-filling tool, only work on primitive parts and don’t
support parametric re-evaluation.
4. The application automation framework that was already powerful has been extended further. Application automation has been included in CADFEKO allowing users to create geometry using scripts. Only a subset of CADFEKO is accessible through the Lua scripting interface
and the rest will be made available in future releases.
Application macros are available in CADFEKO and POSTFEKO allowing users to create their
own tools or download scripts from the FEKO website and then have them readily available
in the GUI interface. Forms or dialogs can be used to obtain user input during the execution
of the script. This allows users to expand the capabilities of POSTFEKO without having to
open the scripting editor each time a custom script is executed.
5. A new set of windscreen construction tools have been developed. The main new feature is
a constrained surface tool that creates a windscreen work surface analogous to a CADFEKO
work plane. This surface is easily specified and conforms to the shape of the windscreen.
Antennas in the windscreen can then be defined in this work surface, using a regular 2D
work plane which is then automatically mapped to the shape of the windscreen in 3D space.
Antennas in this work surface can be specified using wires, Bézier curves and regularly
spaced wires.
6. EDITFEKO has been completely rewritten and now boasts a number of new features. These
include:
• A new ribbon interface similar to the other GUI components.
• A search bar allows users to quickly find the correct card.
• Window tabs (multiple files) can be re-ordered.
• Support for drag and drop of files.
• Syntax highlighting that makes editing files easier.
• Request, source and load names are included on the card panels (not just a comment
at the end of the first line of the card).
7. The calculation of far fields has been accelerated by implementing a new method based on
a spherical wave expansion. This allows in particular the plotting of continuous far field
data that can be sampled to any resolution in POSTFEKO. The feature is attractive for the
simulation of large gain antennas or RCS of large objects, where normally the far field/RCS
versus angle would show a ripple requiring a fine angular resolution.
