Cloud point iges data

This was originally posted in the 'Surfacing' section but itsprobably more relevant over here.

Hi, I have an .igs file that contains over 180,000 cloud datapoints from a scan that I am trying to import into SolidWorks. Ihave SWX 2008 Premium with the ScanTo3D add-in. When I import the.igs file the cloud points are imported as a 3D Sketch and I amhaving trouble using the ScanTo3D functionality to help me createthe surfaces I need.

This is what the SolidWorks help file instructs me to do:

"Click Open and select one of the following types of scan datafiles in Files of type:

Mesh Files (*.nxm; *.scn; *.3ds; *.obj; *.stl; *.wrl; *.ply;*.ply2)

PointCloud Files (*.xyz; *.txt; *.asc; *.vda; *.igs; *.ibl)

ScanTo3D automatically imports textures from 3D Studio .3ds, .obj,and .wrl files provided the textures are clearly linked to the meshfile. Otherwise, the mesh imports with no textures. You can specifythe location of texture files in the Import Options dialog box..

Browse to a file for File name.

Click Options, set the import options, then click OK.

Click Open.

Mesh or Point Cloud appears in the FeatureManager design tree."

I do not get the 'Mesh' or 'Point Cloud' icons in myFeatureManager, and all the ScanTo3D functions are greyed out.

Am I choosing the wrong import options? Can someone maybe point mein the right direction?

Many thanks in advance..SolidworksImport export
