Click here to order! Can your AutoCAD software calculate area properties for a complicated section like this? MassPlus v9.0 can! Easily! Overview MassPlus is an engineering software application which calculates the area properties of any twodimensional 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 9.0 supports the newer versions of AutoCAD. See product comparison mpcompare.pdf.

It computes all the properties we require to run our analysis. The customer service and email response time is topnotch.”Nicholas Valentin, P.E. "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 To demonstrate the accuracy of MassPlus v9.0, accurate values are calculated for the Area, the X and Y values of the centroid, the Moment of Inertia about the Xaxis, Product of Inertia about the drawing's origin, and the Radius of Gyration about the Xaxis 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.

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.
