Apply Base

the apply base feature creates a flat surface on the base struts to ensure platform adhesion during printing use this feature when you want to adhere your lattice directly to the platform where to access solidify (operation) apply base (checkbox) no base without a base, the platform facing surface of the lattice just lightly touches the platform at each strut this will likely lead to under adhesion (part does not fully adhere to platform) with base applying a base extrudes the cross section of the struts down to z zero (represented by the grid in the design engine)
