Error: Object reference not set to an instance of an object at Structure.TStructure.CopyToCCPlusClipBoard()

When you try to export (either using the Export menu or using CTRL + C) an element from Diamonds to ConCrete Plus, you get the error below:

Solution

• ConCrete Plus can only handle rectangular cross-sections. Round cross-sections are not supported in ConCrete Plus.
• Diamonds 2023r01 contains a bug causing the export function to ConCrete Plus not to work properly. Use the menu File > Export > Export to ConCrete Plus instead.
