Hello Dongxuli,

Thanks, the aesthetic result now looks excellent, could you please try the semicircles with rounded ends, as described in a past post [1]; likewise, added to the aesthetic aspect, it would be important that the area formed by the two semicircles and the two segments was a closed area, on which among other things we could apply a hatch.
