MassPlus Area Properties Software for AutoCAD

MassPlus XG v4.0 has been released!. Now supports AutoCAD 2010 drawings.  Integrated viewer and section properties software with additional calculations and export results to CSV (Excel file).   Batch printing to scale now supported.

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.  MassPlus supports exported 2D profiles from 3D packages like SolidWorks, etc.  New versions 2.1 and 3.3 are faster and supports the newer versions of AutoCAD.

There are two versions of MassPlus.  See product comparison mpcompare.pdf.  See also frequently asked questions mpfaq.pdf.

Both versions have now been bundled!  You can now get both for the price of one!

MassPlus XG v4.0

This version no longer requires AutoCAD.  It can view and print AutoCAD drawings directly and will perform area properties calculations as well.  The number of component areas has been doubled to 100000 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.  v3.3 now supports batch printing to scale using batch page layout and scale dialog box

To demonstrate the accuracy of MassPlus XG v3.3, accurate values which are available for the licensed version are calculated for the Area and the X-value of  the centroid.     You can then compare these to the demo values. 

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

Some comments about MassPlus:

"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.

Installation Instructions MassPlus XG v4.0 MassPlus v4 install.pdf

MassPlus Classic v2.1

New version released 06/06/2008 allows saving of dxf file created from selected entities in AutoCAD.

This version is for users of AutoCAD, IntelliCAD, or AutoCAD compatible software that have AutoLISP capabilities.  MassPlus Classic interfaces with the CAD application via AutoLisp.  For example, steel section properties or any area properties calculated can be imported back into the AutoCAD drawing using the provided AutoLISP script file. You may also print the results directly from the MassPlus window. 

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.
