1 General
Please delete all the geometry that is not to be included in the transfer; the model should only contain the geometry which is actually to be converted (time/cost savings).
Please use the (curve) precision (0.02mm or a greater degree of precision) appropriate to the purpose.
Please do not use any special characters (especially /*%) or umlauts in the names within the CAD system.
Please break down all the geometry generated by other programs (macros, user-defined applications, PDM tools, etc.) so that the model only contains the standard data types.
Associativities cannot be included in the transfer.
2 Preparing CATIA models
2.1 Preparing CATIA models (general information)
- Please delete all non-referenced geometry, e.g.
- all NOSHOW/NOPICK geometry
- all unused details
- Please link all SETS with the "SETS/LINK" function if possible.
- Please deactivate all filters ("LAYER/FILTER"/All function).
- Please use the precision required in the target system
(see above, "STANDARD/MODEL"/Page 2/
IDENTICAL CURVE TOLERANCE = MODEL DIMENSION/10^5).
- Please check the model with "CATCLN" and rectify any errors.
- Please use codepage ISO8859-1
(use the CATIA utility CATAIX to set this codepage if necessary).
- Please do not use any embedded project files (PRJMODEL = TRUE).
- Please use CATIA export files for CAD data exchange; use the CATIA utility "CATEXP" with the option " EXPORT/EXPORT" for exporting the models from your CATIA environment.
2.2 Preparing CATIA models (3D, SPACE)
- Please delete all DRAW geometry (if only the SPACE geometry is to be converted).
- Please use only SOLEs or VOLs, not SOLMs or other solid derivatives that require special CATIA modules (e.g. *PIP,*TUB,*GPR) or change these into SOLEs beforehand.
(SOLMs can only be read into UG and then only as facetted solids).
- Please use the "SOLID/UPDATE" function in all workspaces even if the "FORCE" option has to be used.
- Please do not use any solids/volumes which comprise two or more separate bodies that to not touch (only possible in CATIA).
- Please break down import/smart solids and generate as true SOLEs.
- Please use the "DETAIL/EXPLODE" function to break down solid dittos with which Boolean operations were performed.
- Please do not use any transformed dittos.
2.3 Preparing CATIA models (2D, DRAW)
- Please delete all SPACE geometry not required in the drawing (if only the DRAW geometry is to be converted).
- Please use only CATIA standard fonts (e.g. DSUS).
- Please use only one DRAFT (drawing).
