There is only one file type that uses the .TCM extension:
TurboCAD Mac Drawing
2D or 3D design draft created by Mac editions of the TurboCAD computer-aided design (CAD) software; stores a drawing, including the geometry and display properties; can be rotated and viewed with lighting effects and different camera angles using the software.
TCM files are similar to .TC2 and .TC3 files. All three file types are only used by the Mac editions of TurboCAD.
