I am new to solid edge and i coundnt find the feature recognition tool in sold edge.
When opening parasolid file, picked options but cant see the tool.
any help would be appericated.
The later versions of Solid Edge ST3 and ST4 do not have feature recognition because it does not need it any more - it is essentialy an obsolete function. Feature recognition is an attempt to rebuild a history from non native data such as a parasolid. If you use Solid Edge in Synchronous mode you simply edit the model using the steering wheel or by placing dimensions on the model/assembly.
Your local reseller will explain it to you plus its all in the help and tutorials.
Actually Feature recognition will be back in ST5 ! But only for recognition of hole features. So have some patient. And it will be back soon, because a lot of people still use it or want to use it again.
