GCCEC ANNOUNCED BUG IN CATIA V5R20
GCCEC experienced unexpected trouble using CATIA for modelling support assemblies of ATLAS big wheel muon chambers. Assembly contains several subassemblies with number of parts in each. In one of the assembly parts are positioned on contact using standard constraints. However after insertion of subassembly into mother assembly and positioning, contacts in subassembly are moving into 0.14mm clash. Seems that number:
1st iteration: Adding volumes with similar materials into one; simplification of shapes - removing all details, holes, lugs, etc. and creation of simple cylinders, tubes, etc. keeping initial volume and weight.
: Adding and simplification of shapes coming from 1st iteration.3rd iteration
: Modification of shapes to avoid possible overlaps with other volumes.
