In the beginner section of 3D modeling, you learned how to group shapes together. In advanced TinkerCAD, you will use the skills you have gained to create more complex shapes. TinkerCAD provides you with basic geometries such as cubes and cylinders. You can combine these shapes to create more complex geometries such as a house using the group function. To create even more complicated designs, you can combine shapes to be used to create complex holes.
The example below will walk you through the making of a heart button. It will involve grouping shapes together in order to create a more complex shape and feature.
# Add a box shape to the workspace. Make sure the dimension of the box has the thickness of the desired button. This will serve as the point of the heart.
# Add two cylinders with the same thickness as the box to two edges of the box. Set the diameter of the cylinder as the width of the box. This will create the humps of the heart.
# Using the round roof object, size it to the appropriate dimension for the button hoop.
# Copy and paste<s>r</s> a second round roof object and make it slightly smaller to be used to create the hole for the button hoop.
# Turn the object into a hole and position it accordingly.
# Finally, group the shapes together and the button is completed.

There are some important things to note when modeling for 3D printing. It is important to optimize the print by decreasing print time and material while ensuring accuracy and strength of the part.
# Divide your model into smaller more manageable parts. There are many designs with complex details or large dimensions that would be more manageable prints if split into multiple parts
# Try to ensure that there is one flat surface on the print. This will allow easier print set-up. The flat side can adhere to the build plate, minimizing the need for additional build plate adhesion.

If your design is to be used in (electro-)mechanical assemblies in which there are interfacing components, it is important that you understand three basic tolerancing concepts and to keep them in the back of your mind when modeling or more generally designing these assemblies.
