Problem exporting to .iges and .step

[Galvax]

I'm trying to figure out a way to convert my SketchUP drawings to either .iges or .step formats. I can import my SketchUP files just fine, but trying to save them as .step produces an error:

Failed to save (file address).STEP: No solid objects found.

I can produce a .iges file, but I only get a small partial of my model and a bunch of intersecting random lines.

Hmm - well a couple of things are going to be an issue here. DC's STEP filter works only with solids. Which is the primary use for STEP files.
DC uses ACIS as the basis for exporting the data so all exported objects must be ACIS solids.

IGES is a bit more complex. While it also ACIS a basis it, it will export surfaces and 2D elements. However all surfaces are converted to solids.

Unfortunately, since SKPs are composed entirely of surfaces and edges the do not translate well into either without severe modification. You really need a 3D application that can deal with 3D meshes as its primary mode in other words a Sub-division modeling app.

What do you suggest?

I would try Blender first - it is free.
