Notes for BricsCAD
- When editing external files such as .txt files, the encoding may need to be ANSI in order for Greek characters to appear correctly.
- Automatic layer update in many LMAN procedures does not work, and a security warning about the execution of SDBOX ActiveX controls may appear frequently, without however preventing the commands from running correctly.
- When the command line is not visible on the main screen, some commands, such as ZVPMW, may terminate prematurely.
- The ZDTM command for triangulation of a closed area is not available, although the ZDTMA command is available. The ZMKTOM command for longitudinal profile drawing does not always work satisfactorily when the profile axis is a polyline.
- Some image-related commands, such as ZIMDETACH and ZFIM, are not supported.

Notes for GstarCAD
- If the Coverage Diagram tables do not update automatically, it may be necessary to open and edit the table drawing separately, after first saving it to another location.
- The ZSW and ZSB commands for changing screen color are not available.
- For text alignment, the ZETT command should be used instead of ETT.
- The ZMKTOM command for longitudinal profile drawing works with limitations when the profile axis is a polyline.

Notes for ZWCAD
- In versions earlier than 2025, functionality is limited, and in version 2024 and earlier it does not work satisfactorily.
- The SAA command, which is used to turn surveyed point elevations on and off, is not available in versions earlier than 2025.
- Commands related to LMAN are not supported.
- Detailed cut-and-fill volume calculations are not available, although some supplementary commands are provided with limitations.
- In versions earlier than 2025, contours are generally drawn correctly, but when the number of triangles is large, they may in some cases be created at Z=0.
- In Coverage and Building tables, automatic cell calculations may not refresh immediately and may require re-entering a value in order to update correctly.
