PTC/User Montreal Creating a Sheet Metal Assembly

Topics Covered Skeleton in Sheet Metal Assembly Sheet Metal Parameters Convert Solid Model to Sheet Metal Model Copy Geometry Mirror a Part in Assembly Assembly

Skeleton in Assemblies Skeleton: A special component of an assembly Created only within an assembly Placed before all other components Solid geometry in the model tree Filtered out the BOM and drawing views Specially handled for Simplified Reps and Shrink-wrap features Maintain their own family tables

Skeleton in Assemblies Skeleton: The framework of the assembly Defines skeletal, space claim, interface, and other physical properties of an assembly Defines geometry of components Perform motion analysis on an assembly

Example: Monitor Shielding Shell

Using the skeleton Dependent on Skeleton by CopyGeom VS Completely Independent from Skeleton

Copy Geometry Create a link between assembly components Create a link between external references Advantage: –If references are removed, can be made independent (link is kept!) Beware of circular references!

Sheet Metal Parameters Special kind of model parameters Help centralize Sheet Metal Information Automate the Sheet Metal Design Set up before modeling

Example

Converting Solid Models to Sheet Metal Models Solid Models can be converted by: –Selecting a driving surface Solid model created with thin option –Shelling the model When should you convert? –Corners

Example: Corner Cut Rip

Mirroring a Part in Assembly Creates an exact mirror copy –Independent (Copy) –Dependant (Reference) Part with Reference –No reference to the assembly if datum or plane belongs to original part Subassembly –Always a reference with Original Assembly

Summary Skeleton & Copy Geometry can play an important role in a Sheet Metal assembly Sheet metal Parameters help automate sheet metal models Sheet metal components can be created by converting solid geometry –Very useful for corners
