Here i have attached one component . i need to drafted drawing in understandable way .
Ramesh, What draft angle does the part require? It would be best if someone with SolidWorks 2013 added the draft. Otherwise, you'll only be able to import a "dumb model".
Take a loot at the attached image showing a section of your model. You'll want to add a fillet to the inside. Right now the model has almost no thickness and won't work well if it is produced.
