1. 1 ROOT CATIA P. Biryukov (p.biryukov@gsi.de) (progress report)

2. 2Aim The aim of the work is to make ROOT geometry available in CATIA and vice versa The aim of the work is to make ROOT geometry available in CATIA and vice versa ROOT->CATIA 1.export geometry from ROOT using RootToCatia(char *fn) function (automatically) 2.import geometry to CATIA using macros (automatically) CATIA ROOT Geometry

3. 3Aim The aim of the work is to make ROOT geometry available in CATIA and vice versa The aim of the work is to make ROOT geometry available in CATIA and vice versa CATIA-> ROOT 1.mark geometry in CATIA and specify geometry names (manually) 2.export STEP file with geometry (automatically by CATIA) 3.create file with geometry description (partly automatically using macros in CATIA) 4.convert geometry using CatiaToRoot (char *fn) function (automatically) ROOTCATIA Geometry (STEP) Types, Hierarchy

4. 4 Example: CATIA->ROOT Create a geometry in CATIA

5. 5 Mark the geometry

15. 15 Example: CATIA->ROOT Execute "StepToRoot" function StepToRoot(" myDetector "); it loads STEP file (myDetector.stp) it loads geometry description file (myDetector.txt) and it saves ROOT file (myDetector.root)

16. 16 And as a result of the previous steps the following ROOT geometry was created...... and saved into myDetector.root file Example: CATIA->ROOT

17. 17...now it could be changed... Example: CATIA->ROOT

18. 18 Example: CATIA->ROOT Execute "StepToRoot" function RootToCatia(" myDetector "); it loads ROOT file (myDetector.root) and it saves file with geometry for CATIA (myDetector.txt)
