Springs Upside Down

Hi everyone,

I defined the columns in my model as springs and gave them a stiffness value in global Z in Rhino. For some reason the springs are upside down and I am not able to reverse them. I have never had this problem before when I use Sofiplus .
Is there anyone who had the same problem before and now how to fix it ?

Thanks a lot in advance !

So suppose that your system input is carried out with the following SOFiMSHC-module, where spring 20 will be created between point 1 and 2:

+prog aqua urs:1
head
norm en 199x-200x
end

+prog sofimshc urs:2
head
syst 3d gdir negz gdiv 1000
ctrl mesh 1
spt no 1 x 0 0 0

spt no 2 x 0 0 10
spts no 20 ref 1 cp 1000 type c dz -1
end


This spring can be later on modified both through SOFiMHC and SOFiMSHA:
Via SOFiMSHC:
+prog sofimshc urs:3
head
syst rest
ctrl mesh 1

spt no -2
spts no 20 ref 1 cp 1000 type c dx 1 0 0
end


Via SOFiMSHA:
+prog sofimsha urs:4
head
syst rest

spri no prop dx 0 1 0
mod type spri from 20 to 20

end
