I have a problem with the section plane. When I use the section plane, geometry appears that should be hidden. ![Screen Shot 2021-07-22 at 13.58.23](https://global.discourse-cdn.com/sketchup/original/3X/9/a/9a7265340e395d89e13da4793818720dfc0fb2f4.jpeg) ![Screen Shot 2021-07-22 at 13.58.26](https://global.discourse-cdn.com/sketchup/original/3X/8/0/800a342104cbe4f5f272dcf6f7771ee56b9a6974.jpeg) ---

Can you share the .skp file so we can have a look? ---

I’m not seeing anything I wouldn’t expect to see based on the model and location of the section plane. ![Screenshot - 7_22_2021 , 12_59_54 PM](https://global.discourse-cdn.com/sketchup/original/3X/0/0/002c1760f357474714e5ec66f30b65f02c5cb884.jpeg) With all the tags turned on I get this but again, I would expect to see that. ![Screenshot - 7_22_2021 , 1_00_59 PM](https://global.discourse-cdn.com/sketchup/original/3X/f/3/f3261d895bdcdbb2f1bb29d88326353a2fe8ac28.jpeg) What tags do you have visible in that first screen shot? Wouldn’t hurt to purge the model of unused stuff once in awhile. ![Screenshot - 7_22_2021 , 1_06_41 PM](https://global.discourse-cdn.com/sketchup/original/3X/d/8/d8bf8a0fe3b8a693a0dca1724627b0dcb5522d2a.png) ---

Thanks for your help. I found de problem. when I hide objects through a tag folder, the problem I mentioned above occurs. But when I hide objects through their tag (not through folder) it works fine. ![Screen Shot 2021-07-22 at 15.19.36](https://global.discourse-cdn.com/sketchup/original/3X/b/6/b6c8e54261406afbce2dd96f85609bb8d09d3150.jpeg) ![Screen Shot 2021-07-22 at 15.19.57](https://global.discourse-cdn.com/sketchup/original/3X/4/0/403a7119c23644f3af76e58fc4bc37ee66bbae07.jpeg) ![Screen Shot 2021-07-22 at 15.20.42](https://global.discourse-cdn.com/sketchup/original/3X/5/a/5ac870fb53ce825d34a91f3f18ff7170442a6557.jpeg) ---

That’s odd. I’m not getting the same thing. Does it change at all if you zoom in on one of those areas? ![Screenshot - 7_22_2021 , 1_25_34 PM](https://global.discourse-cdn.com/sketchup/original/3X/e/5/e5bbd492ddd04f25f7bd4df0d51c21b2fe270463.png) By the way, your profile says you are using the free web version but that’s not the case. Maybe you could fix it. ---

Odd. I’m on a PC. I wonder if a Mac user can take a look and see if they get the same result as you do. Maybe @slbaumgartner or @MikeWayzovski ---

Right click the section and choose “Active Cut” from the context menu. Then it behaves correctly. ---

Strange. Unless I’m missing the point, that worked for me. ![section cut](https://global.discourse-cdn.com/sketchup/original/3X/c/a/ca7c65f1ba485f186ddc18fc355b893503253af5.gif) ---

If I right click on the Section Plane to bring a contextual menu and then click on Activate Cut it behaves as it should, as shown by slbaumgartner. ---

There was an oddity in the the first release, (2021.0.338) You might want to update to 2021.1.278 ---
