Open reference
Open reference command opens a surface model file for read-only access. A reference surface can be viewed and displayed using display options for surfaces, and it can be included in calculation processes. A reference surface can not by modified.
To open a reference surface:
1. Select Open reference command from the File pulldown menu.
The Open reference surface dialog box opens, a standard dialog for opening files.
2. Locate and select the file to be opened.
3. Click OK.
This reads in the surface model file and adds it to the list of loaded surfaces. You can use the reference surface in all tools which do not modify a surface.
When a reference surface is opened, the application reads a copy of the model in the RAM memory. It uses this copy during the session and does not detect if somebody else makes changes to the original surface model file.
