Hello all,  
 
I need help from one of you who has access to 123D.  
 
Please take a look at attached STEP file.  
 
my problems: 
 
1- when I import it to 123D design it is huge! ( I don't know how I can set its size) ( I know I can scale it but this is not what I want) Needless to say it is produced in MOI 3D. 
 
2- I tried several times to perform fillet on it I got no fillet! 123D design gave me error!  
 
So, is it possible one of you could check it?
