Visible lines in elevation view in Wallniche

[Joachim Suehlo]

I am creating a window with rounded niches.

For this I use a WALLNICHE command for the cutout and a PRISM_ command for the rounded fill body.

Both PRISM_ and WALLNICHE have invisible contour lines at the planned connection points,

but in the finished object there are still lines visible at border from cutout to fill, when I am in the elevation view and in the basic vector 3D window. But these lines shall not be there.
Any ideas?

I fixed it: got the wrong Mask Value. Now it is okay.

The mask codes (and syntax) should be unified.. (new versions {x} ofc...but they should)
