I'm trying to make a bigger Flower object and I try to modify it and it will not work.
In the odf file of the model add this line
GeometryScale = 1.0
1.0 is default.If you increase it for example 2.0 your model will be 2 times bigger than normal
Also dont forget to make a mshname.msh.opiton file and inside add this line:
-Scale 1.0
Remember the odf and msh.option values must be the same.
I hope i help somehow.
