.MCD File Extension

File format used by Mathcad, a visually oriented math program; may contain algorithms, functions, programs, spreadsheets, and other types of data; used for product development, engineering, and advanced mathematics calculations.

Mathcad was previously developed by Mathsoft but is now developed by Parametric Technology Corporation (PTC). Mathcad 14 and later is also compatible with Pro/ENGINEER files.

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.
