Surface trim problem

Hi, I received a STEP file from a client. When I open it in Moi there is a surface trimming problem. I tried scaling up the model 100x and reapplying the trim. This works for the individual surface, but when I try to rejoining it with its neighboring surfaces, the trim problem appears again. Can you help me with this? I've attached the file and a screen shot.
