1 ROOT CATIA P. Biryukov (progress report)

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

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 Example: CATIA->ROOT Create a geometry in CATIA

5 Mark the geometry

8 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTube tube Number of a record in the file (0, 1, 2,...)

9 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTube tube Type of the shape (TGeoBBox, TGeoTube, etc)

10 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTube tube Name of the shape

11 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTube tube Parent's number

12 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTube tube Names of points, as they are named in STEP file (e. g. in STEP file point could have a name "tube.3" or "myBox.LeftBottom")

14 0 TGeoBBox world TGeoTrd2 trd TGeoTube tube Example: CATIA->ROOT Write geometry description 2 TGeoTrap

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

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

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)

19 Example: ROOT->CATIA The program creates myDetector.txt file 0 TGeoBBox world catiaPoint (0)Point catiaPoint (1)Point catiaPoint (2)Point catiaPoint (3)Point catiaPoint (4)Point catiaPoint (5)Point catiaPoint (6)Point catiaPoint (7)Point TGeoTrd2 trd catiaPoint (0)Point catiaPoint (1)Point catiaPoint (2)Point catiaPoint (3)Point catiaPoint (4)Point catiaPoint (5)Point catiaPoint (6)Point catiaPoint (7)Point TGeoTube tube catiaPoint (0)BottomCentre catiaPoint (1)RMinPoint catiaPoint (2)RMax catiaPoint (3)TopCentre TGeoTrd2 trd catiaPoint (0)Point
