it is very simple procedure if you have model generated from mimics (.mcs file) import in 3Matic as IMPORT PART. you will get all 3D calculated model on right hand panel. now go to finish wizard panel and select 3d entity for which you want to export to solid work if it is ok then go to surface toolbar and select AUTOMATIC RECANGLAR PATCHING and click entities and select your 3d model. after patching done you can export it to IGS or STP format. export this to your solid work ...it will work fine
ok...it is directly done by smoothing operation which is under FIX tab in 3MATIC....or you can also do local smoothing on your part or model by LOCAL smoothing under FINISH tab...or is is better preffered that smooth/clean your model during 3D calculation in MIMICS only or in mask...
