Geom. Appl. 6, No.2, 187-204 (1996).} \itemab Summary: An approach to the reliable boundary evaluation for polyhedral solids is proposed. The approach is based on the three ideas: an approximate evaluation of the Boolean operations is performed; precise calculations are performed at micro-level by using only exact numbers; triangulations are used for the boundary representation. Test examples illustrating efficiency of the approach are presented. \itemrv{~} \itemcc{} \itemut{boundary evaluation; polyhedral solids} \itemli{doi:10.1142/S0218195996000137} \end
