There are 2 file types use the .MCD file extension:
1. Mathcad Document
Document created by Mathcad, a visual math and engineering program; contains multiple types of data, such as algorithms, functions, programs, and spreadsheets; often used for storing complex engineering calculations.
Mathcad Prime now uses the newer .MCDX format. You can convert MCD files to the MCDX format by opening them in Mathcad Prime and using the Mathcad Prime 2.0 XMCD, MCD Converter, which is available from the Input/Output tab on the program's ribbon bar.
NOTE: Mathcad was originally developed by Mathsoft but is now developed by Parametric Technology Corporation (PTC). Mathcad 14 and later is compatible with Pro/ENGINEER files.

2. MiniCAD Design File
Design created by Vectorworks CAD applications, which were previously developed under the MiniCAD brand; contains a design draft such as a technical drawing or a 2D or 3D model; used for storing drafted plans before construction or manufacturing.
MCD files were used through Vectorworks version 12, but Vectorworks now uses the .VWX extension in versions 2008 and later. Version 2008 was the successor to version 12.
NOTE: MCD files can be converted to VWX files in Vectorworks 2008 or later. VWX and some MCD files can also be viewed with the free Vectorworks Viewer programs, which are named "Vectorworks YYYY Viewer," where "YYYY" is the four-digit calendar release year of the viewer.
