Often, when working with complex files, you may find yourself showing and hiding sets of related objects in the tree. For instance, if you have a CAD model and measurements of several sub-systems on an assembly, you may wish to view only a given sub-system in the graphical view.
For this purpose, you can create layers. You can assign objects to certain layers, then show or hide layers. This serves as a very quick way to show and hide multiple objects at once.
Every file contains a Default layer that cannot be deleted.
From the menu, select View>Layer Manager.
In the SA file, show only those objects you’d like to appear on the layer.
In the Layer Manager, click the Make New Layer button.
Type a new name for the layer, then click OK.
The Layer Manager will show the new layer and indicate the number of objects on the layer, and the number of objects currently visible.
In the Layer Manager, select one or more layers to hide or show.
Click one of the following buttons:
Hide. Hides the selected layer. Objects already hidden remain hidden.
Hide Only. Hides only the selected layer. Objects on other layers are shown.
Hide All. Hides all layers. The only remaining visible objects will be those that don’t belong on a layer.
Show. Shows the selected layer in addition to the objects already visible.
Show Only. Shows only the contents of the layer, hiding all other objects.
Show All. Shows all layers. The only remaining hidden objects will be those that don’t belong on a layer.
In the Layer Manager, select the layer to rename, then click the Rename button.
Type a new name for the layer, then click OK.
In the Layer Manager, select one or more layers to delete.
Click one of the following buttons:
Delete Layers and Entities. Deletes the layers and any objects on those layers.
Delete Layers - Leave Entities. Deletes the layers but any objects on those layers remain.
Right-click on the object in the tree or graphical view and select Layer Info from the context menu.
The Layer List dialog appears, showing the layers that currently contain the object.
Do one of the following:
To remove the object from a layer, select the layer and click Re- move From Layer.
To add the object to one or more layers, click the Add to Layer button. In the Add to Layers dialog, select the layers you’d like to add the object to, then click OK.
