How do I fill a hole bounded by curves?


I am doing the difficult part of the model at the moment, I need to fill the hole although the model is mainly curves so it’s difficult to do.

Here’s the model I am making. (Ignore the desktop screen on the right)

If anyone wondering what I am making, here’s the one I was talking about. (The yellow box outline by black, next to the gangway in front of the train.



you need to supply links that aren’t locked or require personal information to access…

it’s better if you download to your desktop and upload the image here…


Sorry, can’t upload two images at the same one.


have a look at some of the WIP’s at SketchUcation…

like this German Tramway by jo-ke

there are others trains there as well…

Next time, activate the window you wish to grab and then do ALT+PrintScreen to only grab the active window (instead of the whole desktop.) It is now on your clipboard. Paste it into a post in the forum, or into your favorite photo editor, etc. And you can also resize the SketchUp window for a min too reduce the size of the image here on the server. (le, look at all that wasted blue space.)

(Moving to SketchUp category.)

You can use the Curviloft plugin for that.

Hi James,

You can create two solids from the existing sides (the one to the left and the one at the top). Extend them to the full length of the shape. After grouping them, place them on top of each other and use the Intersection tool - that way only the area over which they intersect will remain, which will be the completed shape that you are looking to fill. It will also be a solid then too.
