I have been trying to model spring supports but i keep geting this error even though i have tried matching the same rset name here
The “number” in sofiplus is within the group.
For rset you need the element number.
Assuming a group divisor of 10 000, number=201 and group=20 yields element number 200 201.
If you need to double check, look at the spring element numbers in wingraf (after creating the springs, before creating the rsets)
