Draft Angle for Plastic Parts
There is a part which designed without draft angles. So now I need to add draft angles on it for moldability. Is there a simple way to do that ?

Depending how complex the part is, you could go into the Extrudes and add the draft from there. If its being molded you can get away with as little a half a degree in some instances.
first decide what manufacturing process you are dealing with if u dealing with 3D printing no no issue of draft angle and if u dealing with mass production injection molding then draft angles very necessary
check in tool almost all tools are providing draft analysis feature so u can identify
positive and negative draft angle and later u can go for draft if there is complex part and ask to plastic part designer to provide sufficient draft angle for various feature
check the following videos. you will get some ideas.

Draft feature is what you looking for, but may not work for complex parts. Do a copy of you model first.
Activate mold tools add on first. ( right click on features command bar and then activate it.
Use draft analysis and decide what draft do you need; textured finish or without texture. minimum draft of 1 degree or bigger, if that will be possible, i recommend minimum 2 degree. Draft feature will help you, if your part is to complicated may not work, but Draft feature is the easiest way.
Draft feature can be find it in features command bar too.
With draft analysis on is pretty easy to be used.
Other way will be to go feature by feature and activate draft in each feature. Look for Draft on/off in each feature.
Good luck
Ioan is right. Use drafting feature to do this...You can use Solidworks or Catia drafting feature.
