Using sketchup to turn a 2D drawing into a 3D model?

Yesterday I found an STL file where someone had teken a 2D drawing of a ship and somehow turned it into a 3D model. Looked like he had meticulously cut a printed drawing apart and glued it together.

Is there a Sketchup add-on that will do this?

Something like key rotate?

Which version of SketchUp are you using? Your profile indicates you are using SketchUp 2017 Make but you posted in the SketchUp Web category.

Am using 17. Sorry about that. New to the forum

I put the thread in the right category, then.

In what format is your “2D drawing”?

The file I found was an STL, but I already had the image they used as a jpeg. Trying to figure out how they did it. Seems like a lot of work to do it manually.

There are numerous examples of working with 3-view images to create a 3D model. Search for tutorials on modeling cars, for example. It requires that you import the image as an image into SketchUp and then trace the thing and do some intersecting. There’s no way to do this automatically, though. It takes patience to do it but it can be done. Since the craft is largely symmetrical, you can probably get away with modeling just half of it and then copy and flip to create the opposite side.

This is probably not the sort of thing you’d want to start with if you are new to using SketchUp.

I’ve been using it a couple of years now. Typically I do OK with it but some things are still eluding me.

I’m probably already using the technique you describe except I’m not dissecting the original image as they did. I leave it intact but move the shapes as needed. Was hoping there was a program that could somehow do this.

Anyway, I appreciate the assistance!

You could edit the image to create three separate images and orient them in SketchUp so you don’t have to rotate the model content you create. Or you could just use three copies of the image.

Good luck with it.
