About Using Layers in Welding
You use layers in a model or a layout as an organizational tool. By associating items with a layer, you can collectively manipulate features including deleting, reordering, suppressing, or hiding and unhiding them as necessary.
While there is no specific default layer for welding, you can set a default layer for all welding features (light, surface, and solid) by setting the configuration option def_layer to layer_weld_feat <layername>, where layername is the name you assign the layer. For example:
def_layer layer_weld_feat allwelds
Weld features you create after setting this option are automatically added to this default layer.
You can customize your welding layers, and how they display, by clicking 
> from the Model Tree.
> from the Model Tree.Creating a Layer for Light Welds Only
You can create a layer for light welds only from the Rule Editor dialog box. Set both the rules described below:
Look for = Feature Look by = Feature Attributes = Type Comparison = is equal to Category = Welding Value = Welding Feature or any other welding type. | Look for = Feature Look by = Feature Attributes = Type Comparison = is not equal to Category = Miscellaneous Value = Has Quilts |
