HULL DETAIL.skp (688.6 KB)
I’m modeling this fantasy submarine with a double hull, an inner and an outer hull. Here’s a detail. You can see each hull is curved a little.
Each hull is shown with SU’s 1 pixel thick faces. Very nice, but that’s not what I want. Each hull is thick, maybe 4x thicker. I do not want to show it on the ends only because the model will have cross sections at various places.
This should be simple. What am I forgetting??

Can’t look at the model on mobile but you might be able to use Fredo Joint Push Pull Thickener to give each surface thickness.
Hopefully they are modeled a distance apart from one another, and I think it best to think about modeling like how we would build things in the real world.
There is no ‘1 pixel’ thickness. SketchUp models surfaces - that surface is infinitely thin…
I model Airstreams for a client - I create the entire shell and use the thickener to give the walls ~2” of thickness. But I do this on the entire shell of the camper.
If you can achieve what you want with basic tool, see this SU file, otherwise, use the Plugin pointed by bmike.
You need to use it on both of your hull plates to give thickness to each of them.

These are great explanations for thickening my curved surface. Thanks. I will use them … but this does not address the problem of cross sections. I want the thickness of the hull to show up black in the section, but this will give two faces.
then maybe create another volume using copies of the two inner wall skins and put it on a separate tag called void and only turn this on in sections… or alternatively just edit the 2d section cuts and isolate the void surface there…
The version of SketchUp you list has the ability to add Section Fills in the scene settings.
Or use an extension like my SectionCutFill [from SketchUcation’s PluginStore] to add face to the section cut and customize it…
In passing… you say the two hull surfaces are ‘pixels apart’ - but in reality a submarine’s hull is relatively thick to withstand the water pressure etc…
You have to make it solid then and use the section tool and scenes to show a cut into the sub.
I would model the shape of the sub, then use the thickener plugin to increase the thickness. If you are careful with your geometry creation you should be able to make this solid.
I will see if I have time to show a sample later.
If you just need to see the ‘void’ between the two hulls as black, use section cuts.
Here I made a rough submarine shape using SubD:
I copied it over and I used Fredo Joint Push Pull Thickener:
Then used the section planes, scenes and a presentation style to show the cross section:
Modeling a curved shell like a submarine could be tricky / difficult, but Section Cuts and Styles / Scenes are basic functions of SKP.
