The Set CoG by Code Envelopes function enables multiple definitions of CoG based on codes. This function is found on the Items menu of the Items window.
In the table-view, select the weight items to update. Alternatively, press CTRL+A to select all items. Next, select Set CoG… on the Items menu and choose VCG, LCG, TCG or All.
Next, a window asking for code type will pop up. Select the code type to be used for setting the CoG and click the OK button. CoG for the selected items will now be calculated as halfway between CG_min and CG_max for the selected code type.
