Hi all, I’m new to the SketchUp forums. I have a question about filling arcs… When using the Arc tool to draw quarter and semi-circles on a plane, then drawing the same arc above and connecting the two ends with straight lines, the arc is not filling and I have no way of getting it to fill. I’m us…

If your arcs are truly coplanar and all the edges are closed it should generate a face. Download your model to your desktop and upload it here on the forum by dragging the file into a reply window. If we can see the model we can likely tell you what is going wrong. Edit: having just re red your po…

Hi, thanks for your quick reply! Yes, I think you have the idea of what I’m trying to achieve but how do I push/pull a line? I do not want the face of the arc to have thickness. I’ve downloaded models from the 3D Warehouse which have this single line thickness arcs on two and three planes. A good e…

You must push pull as a face. Erase the back when you’re done if you like.

[image] couerdelion: but how do I push/pull a line? I do not want the face of the arc to have thickness. You don’t. Create a face by drawing a line between the endpoints of the arc and then extrude the face. Erase the lines to leave just the curved surfaces.

So how would I create a 3D fill then? [3d fill]

I’d use Follow Me for that instead of Push/Pull. [Screenshot - 5_23_2020 , 5_17_37 PM] [Screenshot - 5_23_2020 , 5_17_56 PM]

You would model faces across the plane of the back side. Let’s make sure we are talking about the same thing: SketchUp is a surface modeler, there is no fill, nothing is solid. Everything is a collection of planes. An object can have outer bounds but it is still “hollow” inside.

@DaveR Can you clarify how “Follow Me” would achieve this please? @endlessfix Can you clarify how as a “surface modeller”, SketchUp could produce a solid face fill as per the example I’ve provided? Thanks

[image] couerdelion: Can you clarify how “Follow Me” would achieve this please? I drew the shape shown in green in my first screen shot. I also drew a path consisting of a couple of line segments and an arc. I selected the path, then go the Follow Me tool and then clicked on the green face. C…

[image] couerdelion: clarify how as a “surface modeller”, SketchUp could produce a solid face fill as per the example I’ve provided? All geometry in SketchUp is made up of zero thickness surfaces. To “fill” something you model surfaces around the area you want to enclose. It’s a little diff…
