Hello,
based on some similar parts it seems to me that the orientation and description of 70681 should be changed to:
Arch 1 x 3 x 1 Inverted with 1 x 1 Cutout
from Slope Brick Curved 1 x 3 with 1 x 2 Inverted Cutout.
The similiar parts are:
6806 Arch 2 x 6 x 0.833 Inverted
78666 Arch 1 x 2 x 1 Inverted
18653 Arch 1 x 3 x 2 Inverted
