Xrefs for Civil Types

1. XREFS –

1.1. What types of files could be XREFFED?

1.1.1. Any file with line work that is typical throughout the entire project.

1.1.1.1. MSTR or Base Files

1.1.1.2. Design Files

1.1.1.3. Titleblocks – Not the Titleblock information, just the border line work

1.1.1.4. Standard Notes and Construction Notes. This way, when the notes need to be changed you only change them in ONE place and they are updated in all sheets.

1.2. What is the difference between Attached and Overlay?

1.2.1. If you Attach file A to File B and then Attach File B to File C, both File A & B will show up in File C

1.2.2. If you Overlay File A into File B and then Attach or Overlay File B into File C, only File B will show up in File C.

1.2.3. Attached XREFFS will carry through from one drawing to the next, creating a nested xref.

1.2.4. With a nested XREF, you have little control over the layers that are in the nested file.

1.2.5. Another problem is when File B is detached or the path is lost, you will see file A listed as Orphaned. This can create some major headaches when trying to detach or reload the Orphaned file.

1.3. How can XREFFS be done?

1.3.1. Xrefs that are placed on layer 0, will allow you to control Freeze\Thaw settings for individual layers using the Express Tools Layer commands. If you place an Xref on a different layer and try to freeze a layer by selecting it, it will freeze the entire xref, since you are telling ACAD to freeze that layer.

1.3.2. Overlay – This allows you to control the layers of the individual xreffs in each sheet file and eliminates the problems that come with nested xrefs.

2. Renaming XREFS –

2.1. By renaming the xref files, we can define layer settings files that we can load from the server to make sure that the layer settings are the same in each sheet of the set. Renaming the xref in the Xref dialog, does NOT change the drawing name, it just changes the first part of the layer name

2.1.1. Example, You Overlay 123-07MSTR.dwg into your sheet, then you can either re-open the XREF dialog and click on the name of the xref twice (slowly, do not double-click) and then type the name you want to change it to, in this case, you would want to rename it to MSTR. Now when you open the layer dialog, instead of seeing 123-07MSTR|Layernames, you will see MSTR|Layernames. The Pipe symbol (|) lets you know that the layer is from an xref and the string n front of it is the Name of the xref.

2.1.2. The other way is to use the Rename command and listed under Blocks will be your Xrefs. You can select the Xref you want to rename and change the name in the dialog.
