MassPlus Area Properties Software for AutoCAD                   

MassPlus XG v5.5 has been released!. Now supports Windows 7, splines, plastic section modulus Z,  and AutoCAD 2012 drawings. New version directly interfaces with AutoCAD via autolisp.  Selected entities for calculation are now displayed in the MassPlus graphics window. Integrated viewer and section properties (moments of inertia, section modulus, etc.) software.  Results may be exported to CSV (Excel file).   Batch printing to scale now supported. Release date January 2, 2012.   Release v5.5 notes - more info

Can your AutoCAD software calculate area properties for a complicated section like this?  MassPlus v5.0 can!  Easily!

Overview

MassPlus is an engineering software application which calculates the area properties of any two-dimensional AutoCAD geometry.  One common application is for analyzing steel section properties and aluminum extrusions.  MassPlus supports exported 2D profiles from 3D packages like SolidWorks, etc.  New version 5.0 supports the newer versions of AutoCAD.

Previously, there are two versions of MassPlus, one standalone version v4.0 and and a version that worked within AutoCAD, v 2.3.  MassPlus v5.0 consolidated both versions into one executable with a streamlined autolisp interface.  See product comparison mpcompare.pdf.  See also frequently asked questions mpfaq.pdf.

MassPlus XG v5.0

This version no longer requires AutoCAD.  However, if you do use AutoCAD, you can select the entities you wish to do calculations on and pass it on the MassPlus via the supplied autolisp script and lisp files.  The selected entities will be displayed on the MassPlus graphics screen.  Running MassPlus asa standalone software can view and print AutoCAD drawings directly and will perform area properties calculations as well.  The number of component areas has been doubled to 200000 and several new values are now calculated, including maximum section width and height.  In addition, the results can now be exported to a comma-delimited file (CSV) which can be read by Excel.  If desired, you can import the file into an AutoCAD drawing using the Insert Ole Object command.  v5.0 now supports batch printing to scale using batch page layout and scale dialog box

To demonstrate the accuracy of MassPlus XG v5.0, accurate values are calculated for the Area, the X and Y values of  the centroid, the Moment of Inertia about the X-axis, Product of Inertia about the drawing's origin, and the Radius of Gyration about the X-axis of the drawing's origin.     You can compare these values to your current calculations.

The centroidal axes are also displayed providing instant visual confirmation if the section is being correctly analyzed.  A ten day demo version is available.

Some comments about MassPlus:

"I recommend MassPlus v4.0 to each one who deals with properties of cross-sections.  It works very well with my IntelliCAD.  There is a quick email answering if you have any questions"  Theodore V., Civil Engineer, Greece

"I have tried some other software packages. The factors I consider before choosing the right package are cost, flexibility and complexity. Your software just fell in the right place with immediate CAD-linked feature, reasonable cost,and straight to the point – section properties software for section properties calculations without much complexity. You also gave me confirmation with your online one-user shape testing result which I think is an excellent service. Thank you. All the best."  Kwang Hui, Kong, Tasmanian Consulting Services Pty. Ltd., Tasmania, Australia.

"What a major upgrade!  This is a fantastic improvement.  I intend to upgrade right away." James K. Grant, James K Grant Associates Structural Engineers

"I was impressed with the quality of the results.  We passed along your results to the group involved in analyzing complicated extruded sections who could benefit a lot using your product." Gus Kreuzkamp, PE, Sr. Coastal Engineer, Applied Technology & Management, Inc.

Free calculation offer.  Instead of providing a trial version, CSUI is now offering free calculation for one shape per user.  Email sample drawing to mpsales@slickwin.com and CSUI will send you the results.  Please do not send raster images such as jpgs, tiffs, etc. 

The drawing must contain only one shape!  All drawing entities that are not part of the shape such as dimension lines, text, graphics, and unexploded regions, must be removed and that the shape is hatchable before submission.
