How to Combine and in Tinkercad?

Understanding Object Combination in Tinkercad

Tinkercad is a user-friendly online platform for 3D design and modeling, allowing users to bring their ideas to life. One of the fundamental skills within this platform is the ability to combine different 3D models into a single cohesive design. This process can enhance your projects and facilitate the 3D printing of more complex objects. Here’s a detailed guide on how to effectively combine and manipulate 3D models in Tinkercad.

Steps to Combine 3D Models

Selecting Models

1. Open Tinkercad and navigate to your project. Here, all your models will be listed in the “Objects Browser.”
2. Choose the models you wish to combine. You can do this by holding down the Shift key and clicking on each of the models.

Combining the Models

1. Once the models are selected, look for the “Edit” button in the left-hand toolbar.
2. Click on “Combine.” This will merge the selected models into one single entity.
3. After combining, you will notice one of the models in the Objects Browser has changed color, indicating successful merging.

Utilizing Tinkercad’s Group Tool

Grouping Objects

1. To group multiple shapes, first, select them by clicking while holding the Shift key.
2. Press Ctrl + G (or Cmd + G on Mac) to initiate the grouping. This will merge the selected shapes into a single object that you can manipulate as one unit.

Ungrouping Objects

1. If you need to separate the objects later, click on the grouped shape and press Ctrl + Shift + G. This action will revert them back to individual pieces.

Changing Object Colors in Tinkercad

Changing the color of your 3D models enhances the visual appeal of your design and helps differentiate various parts of your model. To change the color:

1. Select a face of the 3D model while holding the Ctrl key.
2. If the Properties palette is not visible, right-click any object and select Properties to bring it up.
3. In this palette, navigate to the General section and click the color arrow. A dropdown list of colors will appear.
4. Choose the desired color and see your model transform.

Combining Models in Other Software

Sometimes, you may want to combine models using different software, such as Cura for slicing. Here’s how:

1. On the build plate, select the models by Shift + left-clicking each one.
2. Once highlighted, right-click on one of the models and select “Merge Models.” Alternatively, you can use the shortcut Ctrl (Cmd) + Alt + G.
3. The merged object will appear with a distinct grey bounding box.

Frequently Asked Questions

Can I combine more than two models in Tinkercad?

Yes, you can combine as many models as desired in Tinkercad by selecting them all before using the combine feature.

What should I do if my models do not combine properly?

If the models do not combine, ensure that they are selected correctly and try again. It may also be useful to check if the models are overlapping sufficiently, as this can influence the combining action.

Can I edit the combined model after merging?

Yes, after combining models, you can still manipulate the merged object. You can resize, move, or further modify it just like any other object in your design workspace.
