2、ositioning reminderPurpose/scope of the productWeld Design 1 completes the fabrication and assembly process for industrial machinery by providing a dedicated tool for weld creation, part preparation, and making relevant annotations. The ability to create welds in the 3D digital mock-up facilitates p

3、rocess integration by allowing the designer to manage digital pre-assembly, mass inertia, space reservation, and drafting annotation. 1997 2001 DASSAULT SYSTEMESDASSAULT SYSTEMES - Date Page 4WELDSYMBOLNAMEPARAMETERSX REFPreparationRelimitationDraftingTypefilletHeight2 FacesNYYCsquare grooveLength(r

Clash collisionWelds will be integrated in the clash collision of the assembly. The way to integrate welds in the computation depends on the geome

11、try integration in the assembly.Knowledge ware The weld attributes will be integrated to the knowledge ware. As much as geometric parameters (length, width) or technological parameters (quality). But it will not be possible to define customized attributes defined by the user (user parameter). 1997 2
