Is it possible to import a CDF file into Calc M2/M3?
Importing a version 4 project into M3, might be possible to a certain extent, but a lot of information will get lost. For example, input data for calculations and results, were stored in separate files and cannot be imported. Both the CDF and the associated GDS file must be available and the GDS file must be located where the CDF file expects it to be. To find out this, it is possible to open the CDF file in a text editor (although the file isn’t a text file!), and you will see the path to the GDS file near the beginning of the file. Generally, it is best just to start a new project in M3 and use the GDS file for the geometry data. Other data can be entered manually and/or via a HCL file, if available.
