Solid Inspector

Version 2 availible for SketchUp 2014 and newer!

Version 2 have the ability to automatically repair many manifold problems and provide better information on each error.


 Select a group or component and activate the tool for an analysis of what would prevent it from being a solid manifold.

Alternativly, just open the group or component and activate the tool. Saves you from jumping in and out of the object while editing.


  • Click on an group or component to analyse it for holes.
  • Use Tab (Shift+Tab) to cycle through and zoom to the errors.
  • Use Up/Down Left/Right arrows to cycle between errors.
  • Use Return to zoom to current error.

There was some updates being pushed this weekend - might have cause some disruption. Are you still seeing this?

Also, what OS and what SketchUp version?

OSX Yosemite and Sketchup 2014

Now its installing, but telling me that additional are needed.


The support library TT_Lib² is required in order to use core.rb.

Please download and install the latest release.”

ThomThom's picture

Yes, you must install TT_Lib in order to user most of my extensions. Click on Download and it should open the page in Extension Warehouse for you to download.

(Please beware that Yosemite appear to have stability issues in SU2014. Many have reported crashes. These crashes should be fixed in SU2015.)

Another fantastic tool. Thank You!

Not sure it works correctly/consistently. I made a solid box and removed a face. Then grouped it. It does not find the error.

ThomThom's picture

Can you share a link to the model?

Shawn K.'s picture

I decided to try this out. I believe the object has to at least be a component, and not just a few faces that meet. Have you designated that the joined faces are a component?

John S's picture

I found that the TT_Lib must be installed first to enable the solid inpector tool to show up in the tool bar. I had to uninstall the solid inspector tool then reinstall it. Apparently it must show up after the TT_L in the Preferences list.

Leo J.'s picture

Fantastic, thank you.

D J's picture

Helped very much
was getting stressed for hours trying to figure out why it stated the object not being a solid

many thanks ThomThom


Laura S.'s picture

This is a life saver, thanks! :)

Marcos G.'s picture

Anxious to try this out, but does not show up after installation (altho I get message saying installation complete)

TT_Lib Not Installed is the message upon re-start.

Thank you, Thomas!

Nice plugin, but how to select those highlighted problems and simply delete them all?

Paul S.'s picture

I have spent so many frustrating hours trying to find and plug holes so I can ascertain volumes .......this is an absolute life saver. Possibly the most handy piece of software I have ever come across. Thanks!

So I installed Solid Inspector but the tools won’t come up under the tools tab. Inside Sketchup>Preferences>Extensions> the Solid Inspector shows up and is checked. How do I find the tools?

doesn't work at all for me... I don't know what i did wrong but when i activate the tool and i select the object that was ''not solid'', nothing happened.

I don't know if someone here could help me figure out what's the matter. Thanks

Hmm, I installed the tool but like others, can't find it anywhere. I'm using SU2014. I don't see the Plugins Menu that Salvador mentions above.

Salvador J's picture

Ha ha ha ! I've been one of many who had problems to even find the tool. Ok, after some time searching, voilá! Plugins menu - Thom Thom Plugins - Solid Inspector.

On the other hand, I read that someone had trouble exiting the tool and called it "piece of c$&p". Well, for me (SU 2014 Pro) even tapping the spacebar exits the tool with no error at all. Also, as the author said, click on another tool will exit the tool just as well.

Thom Thom, this is by far one of the handiest tool around. I'm glad I found it. Works like a charm. Thank you very much. ;)

Great extension. Had some trouble installing, and then saw an error message saying that I must run SketchUp 2014 from the installation folder. When I did that, it found the TTLib2 and worked well without any error messages. I installed SU 2014 on a drive that my OS is not on, so that may be the problem if starting SU from the desktop icon.

Finally managed to get my print into a solid format. Thanks.

Absolutely love this plugin! Nice work friend! Cookie comin' atcha!

Freddi P.'s picture

Please explain how to install/activate in SketchUp 8.
There is no "Install" button on the Extensions preferences page. Placing the .rz file in the Plugins folder does not seem to work either...

Zackary A.'s picture

Absolutely brilliant plugin. Really simple and intuitive to use.

Randy M.'s picture

will Solid Inspector work with the latest Sketchup version 14.0.4899 ?

ThomThom's picture

Yes, it should work. Though I'm hearing reports that some people have problems downloading. Checking if there is an EW issue.

Karisfa's picture

I can't find this on my toolbar, or in any other menus. I've installed it, restarted the program...thoughts?

EDIT: never mind, I got it. Bottom of "Tools". Thanks.

Mike A's picture

OMG!!! FINALLY found it... Yeas bottom of Tools Menu... Thanks!! (-\

Natalie S's picture

Love this! But I just updated sketchup and now cannot install this..:(

cant find the tool in the menu

Love it! Thanks for making. I've incorporated this tool into my stardard process flows.

Stefan B's picture

I installed the plugin, but it's nowhere to be found...

James B's picture

I have just spent the best part of an hour trying to find out why one of my 'follow me' shapes was classed as a solid and then the next wasn't. With your tool I found the error in 30 seconds! Thanks heaps!

Oh and while I'm here, a curse on whichever numbnuts at Trimble/Google programmed the FollowMe tool to create hidden internal faces when going around bends!


I can't seem to find the tool to use this.
I might just be derping. :P

Solid Inspector is the only inspection tool I recommend in the SketchUp Help Forum.
The way it “points” to the problem helps users to not only find the error but to learn from their mistake.


I've recently got into sketch up and installed solid inspector and that requirement TT_Lib2, but for some reason it's not working. I've used solid inspector on my model but when I pass the file to a friend and they use their solid inspector, mistakes come up despite mine having none.
I've tried purposely to make a non-solid shape and selecting it, using the tool but still, even though it's a non-solid, no circles or mistakes come up, can you please help me, it's costing me a lot of time having to rewrite over and over the model.
Thank you in advance.

Great plugin, helped me find issues with my model, but after looking at it for a bit I honestly am not sure just whats wrong with it. Half of my model is red lines and circles, I started with a 2d shape and extruded from that, may have trimmed it a bit etc. Is there any suggestions as to what would allow someone to try and close a model up?

Right now the only portion of the model is in red is overlayed with itself in a + pattern. I was going to try and trim it from overlapping but it wont let me due to solid errors, but its sub components are in yellow in my library of parts off to the side.

A good tool if only I understood what was wrong with it to begin with.

Hey Thom!
I have problems installing your plugin.

I have tried to put the rbz file both in C:\Program Files (x86)\Google\Google SketchUp 8\Plugins and C:\Program Files (x86)\Google\Google SketchUp 8\Tools.

I then restart sketchup, and I cant seem to find the tool.

Any suggestions?

I use:
Windows 7
Sketchup Pro 8

I've used this for years. It allowed me to 3D print when there was two co-planar lines or missing/loose lines.

Thanks ThomThom!

Still have the problem of my object not being a solid when I try to use one of the solid tools. No Red or Orange circles apear on my SU.

ThomThom, my solid inspector tool is showing no red or orange circles, so I assumed my model was a solid, however it is still telling me that it is not a solid. Any recommendations?

I love this extension. It is essential to be able to print in my 3d Printer anything I design.

I have a couple of questions:
- I can see SEVERAL red circles and several orange circles. I cannot understand your explanation that a red circle is the hole selected, because there are several at the same time ???
- When the Solid Inspector line in the menu appears ticked , what does that mean? that it found no holes and it is a good solid? or that it is busy searching for holes ?
- If no holes are found and the solid is good for printing, a message saying you are OK would be usefu.

Thanks from Spain , Tom.

Just wanted to say thanks . i've used it a lot in sketchup 8 and has always worked great and a real time saver. Just downloaded sketchup make and getting used to the different layout . Took me a minute to find solid tool after installig it .

This is amazing! After installing this I realize I would never have found all the problems with my model.
Thank you!

ThomThom's picture

Thanks! :) Glad it's of use.

There is a donation link at the bottom of the description if you want to donate a cookie. :D

Tyler Y's picture

Wow, I've had 3D models that I could never print because I couldn't find the error(s). This tool may single handedly change the minds of all those who say "sketchup isn't a good solid modeling tool". Because now it's even easier to use sketchup and fix the problems that arise.


Do you have a way for people to donate? I'd be willing to pony up $10 or $20 as a thanks and incentive for future development.

Steve R's picture

What does a red circle vs. an orange circle indicate? What if the circle surround the entire object and does not indicate a specific leak?

ThomThom's picture

Red is the "selected" hole. You can press the Tab key to iterate over the various holes - it will then zoom to that area.

If it's a large red circle it simply means a large hole or error.

Just lost 4 hours of work because this damn thing doesn't have an option to turn off. Once you activate it you're screwed, there's no going back, no undo, you've lost everything you worked on.

If you want to avoid misery and anger, DO NOT DOWNLOAD THIS PIECE OF CRAP!

ThomThom's picture

You simply select another tool - then it deactivates. Just like all the other tools.

Yay ! Thanks Tom
There is a special place in heaven for you !
