2.       Specify a file to attach, and then click OK.

3.       In the Position dialog box, specify the following:

·          Position File: Check this box if you wish to use settings from a position file (.TWF) for origin, scale, and rotation. (see more information on position files below.) Click the gray button to select a file.

·          Origin: If you are not using a position file, either check the Select on screen box to select the origin graphically or type the origin coordinates in the X:, Y:, and Z: boxes.

·          Scale: If you are not using a position file, either check the Select on screen box to set the scale graphically or type values in the X and Y boxes.

·          Rotate: If you are not using a position file, either check the Select on screen box to set the rotation graphically or type a value in the Degree box.

4.       Click OK.

5.       Respond to any prompts for origin, scale, and rotation based on the previous selections.

Using position files

A position file (.rat or .tfw file) contains raster attributes such as the current scale, rotation, and position. If a position file is located in the same folder as the image file, this area of the dialog box is filled in with the file name in gray letters. This file should have the same name as the raster file. If it does and it resides in the same directory as the image file, you will see it listed automatically in the positional file dialog box. If not, you may browse to a different directory and choose another position file. To use a position file, a position file must be available prior to using the Attach Raster Image command. You can return an image to the settings in its position file or display another loaded image at the settings in a different imageís position file. When you select the Position File check box, the dialog box changes to reflect the settings for the position file. Clicking OK will attach the image at the settings found in the position file. Once the image displays, it becomes an entity just as a circle or polyline would be. You can copy, rotate, and move the image using standard CADopia commands.
