[IsakNaslundBh]

Description:

Related to BHoM/BHoM#1642

Add a couple of lines to this method:

BHoM_Engine/Reflection_Engine/Query/Description.cs

Lines 270 to 298 in 0471f52

	private static string EnumItemDescription(this Type type)
	{
	FieldInfo[] fields = type.GetFields();
	string desc = Environment.NewLine + "Enum values:";
	int m = Math.Min(fields.Length, 20);
	for (int i = 0; i < m; i++)
	{
	FieldInfo field = fields[i];
	//Skip the value option
	if (field.Name == "value__")
	continue;
	desc += Environment.NewLine;
	desc += "-" + field.Name;
	DescriptionAttribute attribute = field.GetCustomAttribute<DescriptionAttribute>();
	if (attribute != null)
	desc += ": " + attribute.Description;
	}
	if (fields.Length > m)
	desc += Environment.NewLine + "-...And more";
	return desc;
	}

Namely, add in the step

                QuantityAttribute quantity = field.GetCustomAttribute<QuantityAttribute>();
                if (quantity != null)
                    desc += $" [{quantity.SIUnit}]";

After the description attribute to allow for display of quantities relating to enum values.
