Has anyone had experience with importing a cloud of points from a 3D scan into solidworks?

We are looking at getting a complex structure and pipework scanned by an external company but I am not sure how successful we will be importing this data.  We have briefly looked at doing this in the past but the data file we received was so large that it was impossible to work with.

I intend to discuss this with the 3D scanning company if it looks like we will go ahead with this, but I thought I would ask for others opinion on this topic.

How does the complexity of the items scanned affect the import?

Is there a good file type to use when importing that I should ask for?

Thanks,

Jason
