Creating New Assembly Models

Your company can create customized templates that you can use to create new assembly models.
• Create new assemblies in the New dialog box.
• Use customized assembly templates.
• Assembly templates include:
– Datums
– Units
– Parameters
– Layers
– View Orientations

Assemblies are composed of parts and other sub-assemblies that you  combine. You can create new assembly models within Creo Parametric either by clicking File > New, or by clicking New
. You can type the name of the assembly and select whether you want to use a default template. Unless you select the Empty template, the new assembly displays in the graphics window with the default datum features associated with the selected template.

Using Templates
New assemblies should be created using a template. Assembly templates are similar to part templates in that they enable you to create a new assembly with predefined general information. Your company has most likely created customized templates to use that contain your company’s standards. Using a template to create a new assembly is beneficial because it ensures that  regardless of who created it, the assembly contains the same consistent set of information, including:
• Datums — Most templates contain a set of default datum planes and default coordinate system, all named appropriately.
• Units — Most companies have a company standard for units in their assemblies. Creating every assembly with the same set of units ensures
that mistakes are not made.
• Parameters — Every assembly can contain the same standard metadata information.
• Layers — When every assembly contains the same layers, it is easier to manage both the layers and items on them.
• View Orientations — Ensuring that every assembly contains the same standard view orientations aids the modeling process.
Viewing and Creating Parameters
Parameters are metadata information that can be included in an assembly template or created by a user in his or her own part or assembly. Parameters are important because they enable you to add additional information to part and assembly models. Parameters can have several uses:
• Parameters can drive dimension values through relations, or be driven by relations.
• Parameters can be used as a column in a family table. For example, the parameter Cost might have a different value for each instance.
• Parameter values can be reported in Drawings, or viewed with data management tools such as Pro/INTRALINK or Windchill solutions.
• User parameters can be added at the model level (part, assembly, or component) or to a feature or pattern.
You can view an assembly’s parameters and create new ones by clicking Parameters from the Model Intent group in the Model ribbon tab.
You can create parameters that accept the following types of values:
• Real Number — Any numerical value. For example 25.5, 1.666667, 10.5E3, and PI.
• Integer — Any whole number. For example 1, 5, and 257.
• String — Any consecutive sequence of alphanumeric characters (letters or numbers).
• Yes/No — Accepts either the YES or NO value
