Issue with the cut command: Cutting cube from sphere

[Anti7932]

Hello Everybody!

I want to generate a barrel-shape (truncated sphere) which is cut on the top and on the bottom by a cube.
When I want to perform the following code with the cut function, the original sphere has not been cut.

Here is my code:

neper -T -n 100 -morpho gg -morphooptistop val=1e-2 -domain "sphere(0.2,100)" -transform "cut(cube(0,0,-0.15,1,1,0.15),cube(0,0,0.15,1,1,0.15))"

neper -T -n 100 -domain "sphere(0.2,10000)" -transform "cut(hspace(-0.03,0,0,-1),hspace(0.17,0,0,1))"
neper -V n100-id1.tess -cameracoo x:-1:z+0.2 -cameraangle 15 -showedge "domtype!=1" -cameraprojection orthographic -datacelltrs 0.15 -dataedgerad 0.001 -dataedgecol 64:64:64 -print image
