Complement to _FilletEdge.
This script uses headless FreeCAD ( https://wiki.freecadweb.org/Headless_FreeCAD )
The most significant differences from Rhino's _FilletEdge are at the
intersections of non-tangent edges.
Caution: Check the resultant polysurfaces (B-reps) for missing faces.
See script file for setup instructions.
Send any questions, comments, or script development service needs to @spb on
the McNeel Forums ( https://discourse.mcneel.com/ )
"""
#! python 2 Must be on a line less than 32.
from __future__ import absolute_import, division, print_function, unicode_literals
"""
This script was last tested on
- Rhino 8.11.24254.15001, 2024-09-10
Using
- FreeCAD 0.21.2.33771 (Git)
On Windows.
Requirements to run:
1. Rhino 7 or 8. Other versions have not been tested. If you try other versions,
please inform me (see below) of the results.
2. FreeCAD, preferrably the same version as stated above,
https://www.freecadweb.org/downloads.php
installed where Rhino running the script can access it.
3. Modification of the code in the "Variables to modify per OS"... section
below as needed. Notice that as provided, .stp and .py communication files
are created on the current user's Desktop.
211222-220103: Created.
220106: subprocess.Popen now runs in a threading.Timer.
220110: Removed code for PartDesign Fillet since it has less options than Part Fillet.
Added multiple fillet radius input capability similar to _FilletEdge.
220111: Added preview of text dots on edges containing their assigned radius.
Added option to use previous input.
240101: When running on Windows, now searches and automatically sets FreeCAD
version to the latest installed. Also, added command option to change versions
if more than one are available.
240918: To avoid Python process conflicts, the PYTHONHOME environment variable is
now deleted when the script is run in Rhino 8.
TODO:
For previous input option, should the input be merged with any current input?
Maybe?: Allow variable radius fillet input.
FreeCAD only creates variable fillets that have 2 radii and are G1 blended
between the edges so that the target fillet radii can G1 match to
an adjacent fillet at a tangent edge. They are not linearly blended.
