- Version compatibility issues: Projects exported from newer EPLAN versions can require conversion or cause loss when opened in older versions.
- Opaque structure for non-EPLAN tools: Although it's a ZIP technically, many internal files use proprietary formats (.elk/.elc), limiting interoperability.
- Large size for big projects: Compression helps but complex projects with many macros/3D data can still be very large.
- Dependency on local master data: If recipient lacks referenced master data or manufacturer libraries, imports can produce unresolved references requiring manual mapping.
- Limited incremental exchange: No built-in diff/merge for partial updates—typical workflow is full-export/import.
- New parts only – safest for first-time import.
- Overwrite existing – use only if you trust the source.
