I’ve download SketchUp for my drawings project and I need to export only the edges of my 3D model. It means I don’t want to see walls and all of that. but the problem is that even if i’m using a style where you can only see the edges in black on a white background, when I export this in a jpeg format, white is not transparent. So how can I export these edge without any background ?
So we can all understand what you’re doing, might you use the terminology you see in SketchUp.
From here, it sounds like you’re viewing the model in Wireframe wherein only edges are rendered, no faces.
And you want to export an image of the wireframe model which has a transparent background.
Is that correct?
Exporting a PNG with the Transparent Background option ticked will do just that.
Here’s a screenshot of such an exported PNG as viewed in an image editor.
The checkerboard indicating transparency.
You never did tell us what you plan to do with this image once you have it. It would help to know. I frequently use hidden line exports over other images but I don’t ever find the need to make the export transparent. For example, this image has a hidden line export over a rendered image of the model. the hidden line export is just black lines on a white background.
