How to Find Center of Gravity & Projected Area in Siemens NX (Die Casting)

To accurately select a Die Casting machine and calculate Tie Bar load, you need precise data: the Total Projected Area and the exact Center of Gravity (COG) of your shot. In this video, I show you how to extract these numbers directly from your 3D model using Siemens NX. We won't just measure once—I will show you how to set up associative expressions. This creates a permanent COG point in your 3D space that updates automatically whenever you modify the part design, saving you from re-calculating every time. Key Tutorials in this Video: Using the 'Measure Body' tool to find Mass and Center of Gravity. Creating a parametric Point linked to COG expressions. Calculating Projected Area for clamping force (Tonnage) estimation. Creating a 2D sheet body representation of your projected area. Why this matters: Accurate projected area prevents flashing (by selecting the right tonnage), and knowing the COG prevents eccentric loading on your tie bars.
