M3d v6.3 released.
Main enhancement is the support for Nastran include files. When a Nastran file is read, with multiple includes, a unique file number is allocated to all entities contained in the include file. From the file menu you can export an include file by specifying the file number and file name. The file number can also be changed for entities from menu item "Tools->Mesh Management->Set Include File No" so the include file can be modified.
A display group of the include file can be created with menu item "Group->Group From Include File "and specifying the File No.

New graph plotting support added for Nastran response data (from sol 111). M3d automatically collates available response data across the frequency range and displays them in the dialog box. Simply click the available response and add to the plotting window for quick and easy response visualisation.
​
​To try the functionality open  "Sat.m3d" and load the op2 results file "psat.op2" - supplied in the download zip file. Then go to menu item "Post-Processing->Graph Response Data" to launch the graphing app.

Vector based text has been added.

M3d v5.4 has been released on the download page. Now M3d includes an Undo and Redo feature supporting 4 levels of Undo.
