Methods of placement a component on the assembly layers |
Scroll |
During the process of adding a component, you can choose the method of placement it on layers assemblies. To do this, use the Displaying group of elements in the Advanced parameters section. The following methods are available.
On the specified layer — all objects of the added component and all its constituent components are placed on the same assembly layer. The required layer is selected from the list in the Layer field.
On source layers — objects of the added component and all its subcomponents are located on layers with the same numbers as in the base file(s).
The method may be useful if objects in the component are distributed by layers based on certain attributes, for example, there is a layer Auxiliary objects, on which all objects intended for marking, auxiliary constructions, etc., are placed. By changing the properties of the layers, you can manage objects in the assembly: disable the layer's visibility or its projection in the drawing, etc..
Change of the layer state in components does not affect the layer state in the assembly file, and vice versa – change of the layer state in the assembly does not affect the layer state in the component files.
After a component is inserted into an assembly, the method of its placement on layers can be changed during editing component properties during changing position of a component or moving it to another layer. The section below discusses how to control the placement of components of the second and subsequent levels on assembly layers.
Controlling the placement of second- and subsequent-level components on assembly layers
A component of a second or higher level (i.e., one included in a subassembly of the current assembly) can be moved to any layer of the current assembly. This allows you to place specific components from different levels, such as standard parts, on a single assembly layer.
For the transfer to be possible, the subassembly containing the component must be placed using the On source layers placement method. You can quickly move a component to a layer of the current assembly using the Parameters panel: select the desired component(s) in the Model Tree, then in the Properties section, in the Placement on layers list, select On specified layer and select the assembly layer to which you want to move the component. Once moved to the assembly layer, the component will follow the settings of that layer: Visibility, Background, Projection, and Color.
If a subassembly containing a component is placed using the On specified layer placement method, all its components are located on the same assembly layer as the subassembly itself. Therefore, selecting a placement method for components in this case is not possible.
On inserting a component with placement On source layers into the assembly, automatic synchronization of layers may be performed within this assembly. It starts if the assembly file does not contain layers with numbers present in the component file. The result of automatic synchronization is the creation of layers in the assembly with missing numbers. If a component, in turn, contains other components, then the layers are "collected" from all levels. From the source layer to the new assembly layer, the number, color, name, and the value of the Visibility property are copied. Properties Activity, Editing and Projection in the drawing are established by default.
When an assembly with a component placed On source layers is opened, the layer numbers of the assembly and that component are compared and, if necessary, the layers are synchronized.

If a component, placed On source layers, and the assembly containing it are opened simultaneously, then when creating new layers in the component with new numbers, these layers are immediately moved to the assembly, resulting in them having the same – default – parameters. The same happens when you edit a component "in place". |
A layer copied from a component cannot be deleted from the assembly (as long as it is present in the component). When trying to delete, a corresponding message appears on the screen.
While editing a component "in place" synchronization of layers is also possible. It is used in those cases when the component lacks layers with the same numbers as in the base assembly, and it is necessary to create them. To start the synchronization, run the command Synchronize layers 
from the context menu of the root element in the Layer tree of the component.
