Layout Geometry is part of a model, which is a set of objects that define the basic geometric parameters of a model. For example, it can define:

•areas of assembly space that limit its components,

•fasteners,

•the final positions of the moving parts of the assembly (if any),

•limitations of overall dimensions,

•placement of individual components of the product, etc.

Using layout geometry is one of the design techniques for an assembly model (see Appendix Methods for designing assemblies. Teamwork, Top down design with pre-layout and Bottom up design with pre-layout).

Components of layout geometry can be parts, assemblies, and local parts.

Parts and assemblies inserted into the model as layout geometry are stored in separate files. In fact, the model contains only links to files of these parts and assemblies. When transferring such a model to another workplace with it, it is necessary to transfer files of all parts and assemblies, which are sources of its layout geometry.

The local part, built in the model as a layout geometry, is stored directly in the file of this model.

Layout geometry can be added to the model in various ways.

•When working with a part, layout geometry is added from a file of another model.

•When working with assemblies, layout geometry can be added from a file of another model, created in the context of the current model, and also obtained by converting objects of the current model.

Creating Layout geometry "In Place"

Transformation of objects into layout geometry

In the future, you can edit the layout geometry in the context of the current model. If the layout geometry is stored in another file (part, assembly), you can also open it for editing in a separate tab of the KOMPAS-3D window.

For more details on the specifics of editing layout geometry...

The same model can be inserted as layout geometry in several other models, and vice versa, the model can contain several inserts of the same layout geometry.

Elements of the layout geometry (faces, edges, solids, etc.) can be used in the operations of constructing various objects of the model. In this case, the layout geometry itself does not change.

Layout geometry is not an integral part of the product; therefore, it is not taken into account when creating reports and specifications for the model.

Layout geometry is not involved in the definition of the model's CMP.

By default layout geometry is located on a special layer. Layout Geometry and if there are several layers with this name (these layers can be added and removed by the user) – on one of them with the lowest number. If at creation of layout geometry a layer with the Layout Geometry name missing in the model, it is automatically created. By default, the automatically created layer is not projected into the associative drawing. If necessary, you can turn on the projection or transfer the layout geometry to another layer. Working with layers is described in section Model layers.

Building layout geometry as a whole is similar to building components.

During further work with layout geometry, in contrast to working with components, the following actions are not available:

•enable/disable fixation,

•merging into subassembly and subassembly destruction,

•conversion to local portion by Embed in document command.

The integration into a macro-element is available only for objects included in components of the layout geometry. These components themselves cannot be combined into a macro-element.

In addition, the  View – Hide in components menu commands do not cover layout geometry objects. You can manage visibility of layout geometry objects using the Model Tree (see section Methods of Working with Objects in the Model Tree).
