How to select objects that are not parallel to any of the dimensions

[rowanG077]

I have a simple design where I want to select an edge that is at an angle. But no matter what I try I cannot get the edge selected.

This is my part:

from __future__ import division
from cadquery import *

stand_height = 50
stand_width = 50
stand_thickness =  1
stand_supp_thickness =  1
stand_supp_width = 12.5

stand_lip_chamfer_height = 0.5
stand_lip_chamfer_depth = 2.5 * stand_lip_chamfer_height
    
stand = cq.Workplane("front")\
    .vLine(stand_thickness + stand_supp_thickness - stand_lip_chamfer_height)\
    .line(stand_lip_chamfer_depth, stand_lip_chamfer_height)\
    .hLine(stand_supp_width - stand_supp_thickness - stand_lip_chamfer_depth)\
    .line(stand_supp_thickness, -stand_supp_thickness)\
    .hLine(stand_width - 2 * stand_supp_width)\
    .line(stand_supp_thickness, stand_supp_thickness)\
    .hLine(stand_supp_width - stand_supp_thickness - stand_lip_chamfer_depth)\
    .line(stand_lip_chamfer_depth, -stand_lip_chamfer_height)\
    .vLine(-stand_thickness - stand_supp_thickness + stand_lip_chamfer_height)\
    .close().extrude(-stand_height)

show_object(stand)

And I want to add a fillet to the following edge on both sides:

I have tried many things. First selecting faces then the edges. Trying combining selectors etc. But I can't even get the face that is at 45 degrees selected.

It was awkward but I got this to work:

from __future__ import division
from cadquery import *

stand_height = 50
stand_width = 50
stand_thickness =  1
stand_supp_thickness =  1
stand_supp_width = 12.5

stand_lip_chamfer_height = 0.5
stand_lip_chamfer_depth = 2.5 * stand_lip_chamfer_height
    
stand = cq.Workplane("front")\
    .vLine(stand_thickness + stand_supp_thickness - stand_lip_chamfer_height)\
    .line(stand_lip_chamfer_depth, stand_lip_chamfer_height)\
    .hLine(stand_supp_width - stand_supp_thickness - stand_lip_chamfer_depth)\
    .line(stand_supp_thickness, -stand_supp_thickness)\
    .hLine(stand_width - 2 * stand_supp_width)\
    .line(stand_supp_thickness, stand_supp_thickness)\
    .hLine(stand_supp_width - stand_supp_thickness - stand_lip_chamfer_depth)\
    .line(stand_lip_chamfer_depth, -stand_lip_chamfer_height)\
    .vLine(-stand_thickness - stand_supp_thickness + stand_lip_chamfer_height)\
    .close().extrude(-stand_height)

show_object(stand, "stand")

sel = cq.selectors.SumSelector(
    cq.selectors.NearestToPointSelector((stand_supp_width, 0, stand_thickness + stand_supp_thickness / 2)),
    cq.selectors.NearestToPointSelector((stand_width - stand_supp_width, 0, stand_thickness + stand_supp_thickness / 2)),
)

fstand = (
    stand
    .faces(">Z")
    .edges(sel)
    .fillet(1)
)

show_object(fstand, "filleted stand")

I feel like there should be some combination of selectors and InverseSelector that could have done this as well, but I couldn't get there.

You are probably looking for this:

stand.faces('>Z').edges('|(1,1,0) or |(1,-1,0)')

You are probably looking for this:

stand.faces('>Z').edges('|(1,1,0) or |(1,-1,0)')

Wow, that's neat. I was wondering how to select faces that might be otherwise unreachable. Thanks!

edit: Couldn't find it in the docs. Do the generated docs not track master, or do they need independently updating?
