Use this tool to check the maximum distance between any two surface boundaries. The most useful tool is the Locators > Deviation Min/max measurement tools. Whether you are creating a model, verifying a model, or debugging a translation, there are a number of tools in Alias you can use to check the quality of the geometry you have created. Lower than this will affect processing time. This setting will enhance the success of post transfer processes, such as skinning, that are to be carried out once the geometry is in CATIA.ĭo not set the Curve Fit Distance tolerance in Alias at less than 0.001 mm. If you find that it is not resulting in Alias geometry that can be successfully used in CATIA, then experiment with the Curve Fit Distance-it can set to as low as 0.001 mm. This Curve Fit Distance setting should normally be accurate. The default positional tolerance in CATIA V5 is 0.001 mm, and the AliasCurve Fit Distance setting should be set to 0.001 mm. The Curve Fit Distance is the tolerance to which trim boundaries are rebuilt to (or approximated). What are the curve fit distance tolerances in Alias Use Evaluate > Check Model to be alerted to potential problems: it’s another good practice.Use surface building tools such as Square and Rail Surface, taking advantage of the Boundary Rebuild option to control curvature continuity between surfaces and ensure that surfaces do not contain multi-knots.Avoid using Object Edit > Attach > Attach since this function creates multiknots in Alias geometry that may result in unusable geometry in CATIA.If you periodically stitch the geometry to ensure that the model meets all tolerance requirements, you’ll have a good indication of whether the final model will stitch correctly. The Alias model should be capable of being successfully stitched before export.Periodically transfer models from Alias to CATIA during construction to manage the quality of the model being created.(CATIA tolerances are set for large scale objects as well as for normal scale objects.) While you create the model Set optimal tolerances in accordance with CATIA V5.
Alias CATIA V5 DirectConnect is a stand-alone utility that allows the exchange of 3D model data between Alias and CATIA V5 using the native CATIA part (.CATPart) and product (.CATProduct) files.
