how one can convert/merge multiple solid bodies into single solid body in parts in solidworks????

as I was importing file from SolidWorks to Ansys, I get to know that there is a limit in Ansys for the no. of bodies and parts.So how can I convert or merge the multiple solid bodies and multiple surface bodies in minimum (1 or 2)solid bodies and surface bodies?

You can use the Knit tool to join multiple surfaces together. If the knit bodies form a single watertight surface, it can be converted into a solid body.
Insert - Surface - Knit

You can use the Combine tool to merge multiple solid bodies together. Oddly enough, the Merge tool also takes can of Boolean subtractions.
Insert - Feature - Combine

There are limitations though.
Surfaces with defects will not knit. Surfaces which overlap will not knit.
Bodies which are connected by knife edges, or a tiny point of contact (i.e. a cylinder which is tangent to a another body) will not merge. These often result in the "zero thickness" errors which plague SOLIDWORKS users.

Chances are you'll have a very difficult time forming the bodies in your screenshot into a single solid body. It can be done, but it may take a lot of patience, and experience.
