I am trying to extrude a 1/4 circle around an odd shape. I can get it to extrude almost all the way back to the starting point, but not quite. It leaves the corner open. See Screenshot attached.
Upload your file.
Have you tried selecting the path, activating Follow Me from the menu, then clicking the surface you want to follow?
Yes I have watched so many videos. I have redrawn my path several times. It seems that I can extrude nothing successfully around the path.
Share your .skp file. I’m sure Follow Me can do what you are trying to do. Before uploading it, undo back to before the Follow Me operation so we can see how your model is set up.

The problem is that this is very small and your profile is 1 mm from the corner.
Faces aren’t created there because they’re smaller than SketchUp will make. Move the profile down the path a bit and it’ll work fine.

For the dimensions you are working with I would suggest increasing Display Precision. Also you should be working with Length Snapping turned off.
Thanks again for your help. It is not the first time you have helped me.
I downloaded Fredo RoundCorner Trial version and I really like it. I finally found that the price is US$12.00, what I cannot seem to find is that a monthly charge or a one-time charge or an annual charge. Can’t seem to find that information any where.
That’s a one time charge. Not monthly or annual. Note that it says Perpetual License in the overview.
Thanks again. I will definitely pay the $15.00. It is worth every penny.
Make sure you first have the current version of the Sketchucation ExtensionStore installed and use it to install the latest versions of LibFredo6 and RoundCorner.
You might also want to look into Fredo6’s bundle of extensions. FredoCorner is also very useful as are the other extensions in the bundle.
Is the Fredo6Bundle2022 also a 50.00 one-time charge?
His website is not clear as to how to purchase either the RoundCorner or the Bundle.
Yes. The bundle is also a one time charge.
