Hi all,
I can not BooleanUnion these 2 simple breps. I check the Intersect and it gives a curve as result, but why I can not Boolean Union thess 2 breps ?

Thanks!
you have some tolerance issues here:
you can use the curve from intersect to trim the top surface, delete the lower surface of the top part and join.
but this will not give you a nice result.
did you import the data from some other program?
strongly recommand to remodel the 2 curves with proper fillets, extrude and booleanunion…
kind regards - tom
EDIT:
further digging:
i did not check the angles … see @Gijs post.
make sure the radii are proper 2.00 and 3.00 m
also consider cutting the notch later.
ok - with the info of Gijs - remodel everything with boxes is quite straight forward:
_cplane … set a custom rotated cplane
_bounding box for upper / lower element
_setPt (y of the custom cplane for the common / coplanar faces)
_box for the details
_boolUnion / Difference with mergeAllCoPlanarFaces
_filletEdge
make sure to set proper Radii especially the one i marked here:

hope this helps - kind regards - tom
Just a FYI: the sides are not square, e.g:
has an angle of 89.971 degrees
and these are also slightly off parallel:
I second @Tom_P ‘s advice to rebuild these shapes from scratch.
