hello, I’m a new user here, haven’t had any experience with 3d modeling before, so I’m having some difficulties. when it comes to slicing the model (using cura) , it doesn’t recognize the columns as a part of the whole part and makes a gap between them.
how can I correct the model to make it ready for 3d printing?
Thanks

There are inner faces in your model and because of this, it can’t be a solid volume. A solid volume is needed for 3D printing. You can use plugins like SolidInspector or SolidSolver to visualize and try to repair those problems,

Like Cotty says…
What makes a model a SketchUp Solid?
A Solid in SketchUp is a single Group or Component whose geometry meets certain conditions.
When those conditions are met, Entity Info indicates the model is a Solid Group or Solid Component.
Also notice Entity Info indicates the Volume of a selected Solid.
• The geometry must form a single* airtight vessel.
Like a perfect soap bubble … •No gaps •No holes •No leaks
• No extraneous Faces** inside or outside the vessel.
All Faces must serve to enclose the singular volume of the vessel.
• No stray Edges.
All Edges must serve to support a Face that in turn serves to enclose the airtight vessel.
Thus, each Edge supports two Faces … no more, no less.
• No nested Groups or Components.
*A Solid Group or Solid Component may contain one or more separate airtight vessels.
**Best that all Faces are oriented Front Side (white) facing out.
Have a look at this revised portion of the model you shared, now a SketchUp Solid.

Of course, take the easy route first and upload to 3dwarehouse, checking the “I want this to be 3D printable.” box to see how well Materialise fixes things for you.
