Path lines won't close for creating faces

Good morning,
The faces of paths are removed when modifying the paths to reduce some of it. But I’m using the line tool for closing the lines to get the faces to fill in, and still remain open. I uploaded a file of two of the paths from the same area imported. The first path shows the faces and the second path in the model is missing the faces even after trying to close the lines.

you’re talking about places like this ? that you can’t remove the middle part but keep the path ?

you need to clean it up a little more.

then redraw the contours, and delete

am I missing the issue ?

oh, also, you’re working in white and light grey on top of a light grey face and a light grey background.

as you see in my precedent message, I’m removed the big square face on the ground, and I’ve switched to a greenish background.

and now I see what I’m doing.

Thanks for the help. I’m trying to remove specific parts of the pathways without losing the faces in the model. After removing some of the path / streets, and reconnecting the gaps with the line tool, the faces won’t fill back in. The first file uploaded was the wrong file. Please check the latest file. On the left side path which is complete, is filled in propertly. The right side path model is not filled in because the path lines are not closed, but when using the line tool to close the path lines / loop, the paths don’t fill in with faces.
I need to remove some paths and keep others for my landscape



in the latest dropbox file, the right side pathways are missing faces. I tried to fill them back in by using the line tool to reconnect the open path ends, but remains unfilled. The left side path model is the same path model before cutting out portions of the paths which are filled in properly with faces

You can see the reason in your screenshot, there’s a whole bunch of open ends that need to be closed, I’m guessing this is where you removed parts.


Make sure you are filling in the ends in the correct context, within the appropriate group.

Here you see what happens when I close the last one.

I did close all the paths ends, but faces won’t fill in and remain empty. The left side path set is before I removed some paths and filled in properly. The co-planer should be fine which would be another reason for not filling in faces if the co-planer was off. I tried going through each open ended pathway (same paths as you circled) and the faces won’t fill in. I want to remove some paths for my landscape project because some paths are not needed in the landscape and will interfere with the infastructure

thats exactly the result I’m getting in the video when reconnecting the path ends fills in the entire model as one solid object where it should be only the pathways or the other result remains unfilled entirely

So your question is actually, how do I separate just the paths from the other faces.
Here I have used Intersect faces with the make all the edges cut through, weld to clean up the extra joins, the you can select it all and shift double click the parts you want to keep and delete the rest.
I didn’t bother selecting all the other paths but you should get the idea from this.

Thanks ! Using the shift key I didn’t think of-will try that to keep and delete what is not needed. I found another option just recently, by using the “DRAPE” tool in native sandbox of SU, provides an easy and faster cut on the paths without going back and refilling in the paths–and saves an extra step of work process. Please see uploaded sample of the newer option. Thanks

That helps a great amount ! Using the tools “intersection” and “weld” saved a lot of work.

You could also look at Fredo’s remove lonely Vertices, part of fredo tools, I didn’t use it here but it may have been useful.
And Thomthom’s Edge tools, it has close edge gaps and remove tiny edges (I think). They may be useful if you do more of this sort of thing.

Thanks ! I think everything is a lot better now. I’ll check Fredo’s removal of lonely Vertices–which I recall in a youtube video of Sketchup tutorial. Another reason for removing portions of my path infrastructure (which are imported prefabs ), is I already assembled bigger sidewalks and paths from scratch and looks more realistic than the imported prefabs–as shown in the sample model of a double lane road
