Grasshopper ground cut

Dear experts! Perhaps someone has already encountered this problem and there is a solution.

When i work with Grasshopper, when you display (Draw) Grasshopper geometry, a specific surface appears that prevents new and previously created objects from displaying. I work with a super formula. It’s built near the origin.

UPD 210916 The solution was found. The fact is that if there are several objects in the code, and one of them is many times larger, trimming occurs. If I use proportional objects, this can be avoided.
