Layer Linking

Layers created in VectorWorks are independent of each other. Each design layer has its own scale, view, and render status. In VectorWorks Fundamentals, however, a layer link can be created that combines the geometry of several design layers, including workgroup-referenced layers, onto a single design layer. The linked objects on this design layer display in the same view and scale, and share the same render status. This can then be used to give an accurate depiction of how objects in each layer work together. For example, the various floors of a building can be drawn on separate layers and then linked together into a new layer to form an entire building.

In VectorWorks Fundamentals, consider using viewports instead of layer links, as they provide a better and easier way to present drawings.

In the VectorWorks Design Series, layer links are being superseded by design layer viewports. Layer links cannot be created, but for backward compatibility, existing layer links can still be viewed and edited. See Presenting Drawings with Design Layer Viewports.

The layer link is created on a new design layer that contains links to the existing design layers of the drawing. 3D objects on selected layers are automatically linked; 2D objects can be projected onto the layer link. Once the layer link is created, updates to the design layers are automatically reflected on the linked layer when a screen redraw occurs. However, this updating occurs only in one direction; any new objects or details added to the linked layer will not appear in any other layers. Linked objects cannot be edited on the linked layer; they must be edited on their source layer.

To create a layer link:

1.	Create a new layer, and then make it the active layer.

This layer shows objects on all linked layers and any changes made to them.

2.	Select View > Create Layer Link.

The Create Layer Link dialog box opens; the layer being linked to (the currently active layer) is not listed. Workgroup-referenced layers display in italics.

3.	Select the design layers to be linked from the list of existing layers. Sheet layers are not displayed.

4.	Select Project 2D Objects to display any 2D objects in a view other than Top/Plan.

To project 2D objects after a layer link has been created, select and then unlock the layer link object. Select Project 2-D Objects in the Object Info palette.

Click OK.

Linked layers are locked objects. To unlock a linked layer, select Modify > Unlock; double-click on an item in the layer link (or select Edit Design Layer from the context menu) to return to its source layer and edit it.
