What a silly process but man am I glad you made this video! 4 years later and it's still the same way from what I can figure out!

This works great for another purpose. I make cases for my electronic projects that use LCD displays. Sometimes, like today, I realize that a box I've made before is fine, except that I now want to make it longer so I can add some LEDs, Buttons and Switches. But I can't just make the object longer, because then, the dimensions for the display get messed up. So what I do here, is following this, I split the box at a point behind the display portion. That new piece now can be lengthened without messing up the rest. This works so well.

Dude this video is solid gold. I know it's old but the feature packet hasn't improved in this area in TC so it's 100% still accurate. Thanks for the great tips.

Man! I have to come back to this video about every 3 months when I need to do this! Thanks for the video again!

Thank you it worked like a breeze, for those who said it does not work, you need to listen to the man properly and follow his instructions, even if you need to rewind on the youtube video a couple of times in stages. Thanks man much appreciate the tutorial

Just finished a project I have been puzzling over for months. Thanks to this tutorial it all suddenly came together. Thanks for making it clear with an excellent tutorial.

Omg... i sooo need to know how to do this in Fusion 360. Spent a whole day on Fusion 360 and ended up using Tinkercad to do this. Thanks for sharing these very useful techniques!

I have split like 100 models so far but every so often my brain just goes blank and I have to come back to your video. Thanks a lot!

7 years later and this video helped me a ton, thank you for making such great content!

seriously tinkercad needs a cut function

I have to say Thank You for this video! I've been scratching my head on how to cut a model in half to print on my smaller printer for a couple of weeks. This made it soooooo much simpler for me.

Actually works.. thanks. Great video, appreciate your time.

Thank you thank you thank you!!! This was so helpful! Appreciate your work on making this video!

Omg thaaaaank you for this!!!! I couldn't figure out how to do this to save my life haha You are officially my here 😆

Great video. I had to insert a splice in the middle of a part to make it longer. I used your video to make the cut. It worked perfectly. Thanks!

Thank you for this video!!!! Very well done!

im lost, when I go to group objects the one half disappears completely

Excellent video, thank you!

Wow first one of your videos I’ve ever watched thank you so much I had to split a helmet in half on Tinkercad and I didn’t know how

Very useful tutorial ! Thanks a lot !

Thank you 🙏 for nice guide. But I want to print a small Rc plane fuselage which will be hollow inside and now I know how to split but how do I join the parts so they are glued straight and alighted, something that a bit of one slides into the other and the joint is nice?

Thank you so much, this is gonna help a lot with my next print!

Hello sir, was a bit complicated at first but finally got it! Checking in in 2020. Cheers. + Subbed

What if you want to split the items and construct the two pieces with a locking tab to connect them. I'm thinking of how I could make a mount for my iphone lighting cable

i was looking for a way to get 4 'pins' on a front for a box that hold the print with a screen on to move slightly as the print i have seems to have the openings more on the ouside than the stl

I just started learning this process and i'm so greatful for you for teaching this. I was able to create something simple because of you. Much love.

Thank You. Works! Help a lot.

This is exactly what I was looking for! Great tutorial! Thank you!!

Thanks. Just what I needed! :D

Thanks for this cool hint!

Thank you. This is awesome. I have a car part for a LHD car that I need to adjust to RHD. This should make the process much easier

Very nice! Same applies for a horizontal cut? My print is too high and a I'd want a different colour for the top section...

Needed to split a battery holder tray in half. I have a AA and AAA battery dispenser, just needed the 9 volt tray. Worked liked a charm. A 9 hour print went down to 2 1/2 Hours!

Thanks for this!

Thanks for the lesson. Very easy to follow.

Thank you very much for this.

How would ya add supports to a large object? Trying to print a helmet

I found this video several months ago and have been using it ever since. Effective but can get confusing. I modified this process by first duplicating the original object, then sliding one of them down with the cursor until there's a decent gap between the two. Then I follow his method making the two space cubes. Here's my mod - select one of the two space cubes and cursor drag it down over the duplicated original. Now you have two sets of original plus space, clearly showing an original with a left space and another with the right space. Select a set and combine it then repeat with the other set.

Hi, can you show me how I can extend something after I have made it? I’m making some frame guards for a motorcross bike and they need to be slightly longer, but I don’t want to start again as they fit great, just need to be 60mm longer at the top part. The section is like an inverted U, 120mm long, but I need to stretch just that part to 165mm. Thanks

Allo,id like To know if it is possible To do one point 3d prespective ??tanks

Nice, quite learning !

Really helpful video, thanks.

Always wondered how to do this and normally i just use hollow boxes and do it along fangled way but it worked, this is 60 second stuff though, thanks so much.

Thank you, thank you, thank you, thank you!!!! This was the best video I've found on how to slice my files While the layout did change since this video was changed, the same exact steps worked. The buttons were moved and icons were changed, but the functions are all still there and accounted for.

problem I have a Circuler logo but when making the STL of the logo it has also added the transparent square the logo circle sits on. How would I remove the circle from a square.

Greetings, thank you for sharing your knowledge, when you divide pieces and then put them together the joining line is noticeable, you have done something to solve this, success....

Its so strange. If i create a simple box - it works fine. If i have more complex items i cant "zoom" into the items? - is there any guidelines here ?

This broke my brain :) Great video

Awesome tutorial; very helpful, exactly what I needed.

That's really cool. It's now February of 2022 and there is still no better way to "cut" items in Tinkercad?

How do I make 3D print a solid print to give it more strength and durability? Thx

Not sure what i'm doing wrong but when i zoom, it won't zoom close enough to be inside the 'hole', i've tried making the 'hole' the entire size of the grid, but it's as if the 'hole' is a solid object as opposed to a box???

Thanks man! very useful!!!!!

How can I make a mold with a cavity in it and all 4 walls with 2° angles? I’m frustrated.

This was very helpful, but with the new version of Tink I couldn't zoom into (through) the object, so I just clicked copy and pasted both sides making separate copies and that seemed to work.

Other way is to 1. Measure object and make copy 2. divide length by 2 And make box that length 3. Make copy of box and use align tool to put each box on each copy of object you want to split directly at the end of it 4. Combine each box and shape and now u have two halves of the object

Wow, the zoom is gold.

Yes, i found this very useful. Trying to print organizers for boardgames and lot of the designs i find expect me to have a whopping 16" print area lol....i have a 7.8" print area...

If I do this, I just would erase that part of the red shape? what do I do wrong?

Why can't you draw a hollow box around the object to be cut starting with the left edge of the box at the center of the object and dragging its right edge until it covers the right half of the object. Duplicate the whole thing and move it to the side. Then join the first box and object to cut off the right half of the object. Then go to the duplicate and drag the right edge of the box all the way to the left past the left edge of the object and then join that, leaving the right half of the object. Am I missing something ? And I can't seem to simply zoom inside a box hole which encloses an object to manipulate the enclosed object. What am I doing wrong.

Very useful video. My son and I are learning 3D modeling together using TinkerCAD so we can print off our own designs and it's mostly going well, but tips like these can really help.

Love the technique. Using it all the time now. What I am trying to do now with it is make a two part model split with a screw on one side and a thread on the other that will allow it to be printed and then affixed together with the parts aligned perfectly by using the split and not moving the object while making the screw/thread parts. Any idea on a way to do it would be appreciated.

I also like to make my build plate huge so I have more room to work and when my model is done, put my plate by to normal size. Sometimes I'll open two tabs in my browser and copy and paste parts into one tab to make it easier to work with one section at a time and then merge the two together on a single build plate in one of the two tabs I have opened.

Hi the shape menus disappeared! I cant no more drag a shape into the work space because it disapeared.

Still works amazingly

Howdy, My tinkercad interface looks a little diff than yours. I tried to zoom into an object but it stops just outside of it. I tried to change the camera from the top view but also no luck. Is there some setting I need to click on to use this function as I can see where it would be very helpfull. I even tried swinging the plane and backing in but it still stops just outside the object. any help you can give will be much appreciated. starting to think they disabled this function. Thanks.

Does anyone else get an error/ red border around your boxes when you try to group the second time? I select two boxes, make a copy, group them, then select the object to cut out with the grouped boxes. I get an red border around my grouped boxes. PLEASE HELP

i Great videos. I'm designing a 2 sided coin in Tinkercad. I have side A down but I can't figure out how to flip the coin over so side B is facing up. Both sides have some lettering but not very high so I hope I don't need support. it's maybe 1mm high. the coin is 4mm. Thanks

This saved me a lot of time - thanks for the tips. Tinkercad seems to interact with STLs in some ways far better than other modeling software.

Thanks man! You just made my day!

Thanks. Good tips.

really good explanation

Omg Tysm!

This still works thanks

Awesome. Thanks!

Thanks for sharing😀👍

Thanks a lot! Awesome tutorial : )

How to get inside the hole to select the object to cut when it won't move inside the hole from any position?

thank you for this. Helped me through my first complicated chop job. cheers bud

Great, man! You made my day. Thanks!

Thanks for the tutorial, I couldn't get this to work on the current version, I had to use the same method after duplicating the 3 objects instead of duplicating the object to be cut. Then I had to complete the operation twice to get them to split. For some reason the top would remove and when I grouped the bottom it just deleted it like normal instead of leaving two parts. But your steps helped me get there!

If possible, please explain how to divide an ellipse into 9 equal sections. I see Auto Cad tutorials but nothing in TinkerCad. I'd like to apply this info to construction of geometrical design forms.

Great video! Just keep doing what you’re doing! You are awesome!

Ty man, you helped a lot

Awesome! Thanks so much! These features are so hidden in the software.

Third way to select red box...just make the "hole" boxes you used for erasing invisible...then when you've selected box click "show all"...

No Edit Button on my ThinkerCad. Please update the Video. Thanks.

Awesome! This worked great for a project I am working on!

Took a view times, but i got it! Thanks!

nice tutorial, exactly what i needed !

I tried to but it won't it just stay there and glow red and doesn't make holes when I group them

HI. Can you update the process with tinkercad 2023?

How would you connect them back together? If I wanted to make a flat plane bigger than my print bed, how would I make them like a puzzle so they go back together.

Thank you so much

Ironically I've been doing that on my own. My husband just pointed this video out to me.

Very helpful tutorial, thank you.

Wow..! Zooming in into the object is so cool -thanks a lot ! X))

It took me a couple of times too. I think the problem people have is, that they forget that they have to duplicate the object inside the hole rectangles, before doing the combine steps. Once I did that, the light bulb came on. Thanks

One day I'll find a tutorial that tells me how to cut objects that aren't in a straight line

de-select works fine. but my zoom is limited. why?
