Manage links and control points

As you georeference a CAD dataset, you can manage the links and control points with the Control Point Table. The Control Point Table displays the control points currently in memory. These can be the result of adding control points manually, or loading them from a world file.

To open the Control Point Table, click the Control Point Table button in the Review group on the CAD Georeferencing ribbon.

The Control Point Table.

Edit control points

You can edit the x and y value of each control point by clicking its cell in the Control Point Table and typing the new value.

Highlight links

To highlight an existing link, use the Select tool in the Review group on the CAD Georeferencing ribbon. With the Select tool activated, you can highlight an existing link by clicking either of its control points. Once a link is selected, the Zoom To Selected Control Points and Delete Selected Control Points buttons in the Review group are activated. The Select tool also allows you to reposition existing control points. With the Select tool active, hover over a control point; the pointer will change to a vector selection cursor. Click and drag the control point to the desired location. When finished, press the Esc key.

Load control points from a world file

To load control points from a world (.wld) file, click the Import Control Points button Import in the Prepare group. Browse to the file and click Open. Loading a world file overwrites all control points currently in memory.

Delete links

To delete a link, highlight it using the Select tool and click the Delete Selected Control Points button in the Review group on the ribbon. To delete both links simultaneously, use the Delete All button.

Zoom to a link

To zoom to a link, highlight the link using the Select tool and click the Zoom To Selected Control Points button on the ribbon. Each successive click zooms in closer.

Save control points

To save control points to a world file, click the Save button in the Save group on the CAD Georeferencing ribbon. This automatically saves the world file to the CAD workspace. To apply the transformation to all CAD drawings in a given folder, you can create a universal world file. Click the Save To Workspace button to create a universal world file in the folder of the target CAD dataset. To save a world file or universal world file outside of the target CAD workspace, click the Save as New button. In the Save as window, browse to the desired folder, name the file accordingly, and click Save.
