Is there a way to turn a good surface model that's an iges file into a solid model without having to redraw the whole thing to make changes?? Its basically a dumb model.
Of course there is. Depending on your model, and which version of SolidWorks you have (Standard, Pro, Prem) there may be a few different ways.
Check your add-ins and see if you have 'Featureworks'. If so you can use that to get yourself started.
You can also use the surfacing tools to make it "water tight" so that you can knit it into a solid. Use the built in tutorials for more on that.
I'm using Solidworks premium 2014, i have feature works turned on but its not prompting me when i bring in this file.
i'm not on 2014 yet, but I am pretty sure you need to have an imported SOLID body for it to run. but no worries, you can get there. first, use knit or thicken to make the surface body a solid body ( you may need to close some gaps first - can't tell from the images), then you can save it as a parasolid/step/iges and import that as a solid and run featureworks.
Shoot, I think Jeremy is right about the needing a solid body. If you right click on the surface-imported1 in the tree, is the 'Import Diagnostics' choice there? That would help to find any faulty faces. However, where it's just showing a singular surface, I'm not 100% on that either.
Did Jeremy's suggestion to knit work?
Jeremy is right, for featureworks to work it needs to be a solid
If you can't figure it out - attach the original IGES file here so that someone can take a look and see exactly what you have.
When you open the iges file be sure to click on the Options button in the SolidWorks dialog box and set appropriately. If it is a water tight surface you whould be able to get a dumb solid on import. If you want features you will then need to run FeatureWorks.
Try deleting one face, then re-insert the face using surfaces, select "Merge result" and "Try to form a solid".
