Some problems that originate at the creating of 3D model with difficult shapes without the parameters and dimensions of real part

Abstract

The contribution deals with some problems, which originate at the creating of 3D model without drawing documentation details of modelled part. To obtain the dimensions of such undefined real part is often very difficult, especially, if the accuracy requirement is great. The solution of these problems can greatly affect the efficiency of the part manufacturing and so considerably decrease the economic cost for its manufacturing.
