Solid modeler like DeleteFaces script

kleerkoat · October 21, 2020, 1:19pm

i found this script on github that deletes faces like a solids modeler does by filling in the deleted faces. this is something i’ve always wanted in rhino. although it doesn’t work in all cases it does pretty good on simple cuts in the solid and saves tons of time extracting, untrimming, and patching the “holes”.

i’m wondering, if this can be done in python script why can’t it be native within rhino as a real command?

here’s a screen grab of the script in action and a link to the script on github

"""
160531-0601: Created.
160824: Now selection of faces can continue after chain fillet selection.
160829: Adjacent faces are now trimmed to one another and attempted to be joined back into a solid.
        Added bAddCrvs option.
160831: Import-related update.
        joinBrepsWithOneIndividually now allows main breps to start with no faces.
160907-08: Modularizations and now adjacent faces will extend if the solid doesn't heal using other techniques.
160911: Removed brep layer of nesting in orderedLists_AdjacentFLT_perSelFBorders.
        Moved orderedLists_AdjacentFLT_perSelFBorders from brep.py.
160914-15: Now curvesForTrim uses Curve.ClosestPoints before attempting to pull naked edges of polyface breps to face to split.
180612, 190423, 200107: Import-related update.
200107-10: Restarted development of this script.
           Added bHeal and bAddModFaces.
           Now tries Brep.JoinBreps instead of Brep.Join due to forced edge joining of the latter.
           Now determines whether resultant brep is final based on naked edge border counts before versus after processing.

I’m pretty sure V7 will do this if you use sub-object select.

with subobject selection it just deletes the faces, it doesn’t fill it in an retrim

Yes. I had a situation to actually try it out yesterday and discovered exactly what you describe. I’ve been so blown away with the “magical” things that happen to solids with subobject moving that it seemed to me that it would fill holes too.

Perhaps this could be an option on subobject delete somehow? (delete and fill???) @stevebaer

This may be best for @rajaa to take a look at since she wrote DeleteHole. I’m personally not very involved with these solid editing commands.
