How to make a custom section

Select the line(s) and click on .
Choose .

If Section Utility is not starting, close Diamonds and restart Diamonds.
Define the desired profile. Topics that can help you:

- How to make and HSS section filled with concrete
Make sure to uncheck the winks when composing the defined cross section. This will trigger Section Utility to calculate the elastic and plastic cross-section properties.
Why aren't the winks unchecked by default?
- Assume you draw a line in Diamonds and assign an HEA 300 to it.
- You select the line and open the section properties .
  The properties in this dialog are often rounded values because they come from a catalogue.
  While Section Utility calculates the (elastic and plastic) properties based on geometrical formulas. The Section Utility results are therefor exact and differ a little from the catalogue values.
- If you would send the cross-section to Section Utilty, then close Section Utilty without changing anything to the cross-section, you expect to still have the same cross-section properties, right? Well that’s because the winks are checked by default.
If you want to perform a steelcheck on the section, don’t forget to define the imposed classes.
Close Section Utility. Take the section back to Diamonds.
