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 7.0 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 v7.0 consolidated both versions into one executable with a streamlined autolisp interface.  See product comparison mpcompare.pdf.  See also frequently asked questions mpfaq.pdf.

“Versatile software and excellent customer support.” Tim VanderMey, Proton Design, Inc.

"MassPlus is just what I needed to supply data for windload calculations!" T.L., Orlando, FL

"I originally found it by doing a Google search and I used it in the past 5 years and found it to be a very helpful tool to calculate properties of very complex shapes." Alwyn McDowall, Skyline Steel

"Thank you for the support, I was not expecting to see such rapid responses for software from a US Company in the UK, but you have quickly and effectively solved the issue that arose. Do pass on my recommendation to others or put it on your website, we find this programme extremely useful.  Cheers."  Kevin Armstrong, Factory-Fit (UK) Limited

MassPlus XG v7.0

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.  v7.0 now supports batch printing to scale using batch page layout and scale dialog box

To demonstrate the accuracy of MassPlus XG v7.0, 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.  MassPlus automatically detects holes in the section.  The section mesh displays the geometry being analyzed

The centroidal axes are also displayed providing instant visual confirmation if the section is being correctly analyzed.

MassPlus XG v7.0 HTML Help File massplus70.chm 

Note: Compiled HTML Help Files (.chm) must be saved locally using "Save" before you can see the topics!  Simply Opening the file will not work! This is a Microsoft security requirement.

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.
