This article will cover the basics of creating 3D models within TinkerCAD. For help with other features and design tips, we may have another article covering the issue, otherwise refer to TinkerCAD lessons or support.

Whether you are designing your own models or double checking a model you downloaded, it is important to know the size your model will print at to know if it will print properly.

To change the length, width or height of a model, select it to reveal five white boxes; one in each corner and one at the top of the object. Use the four corners to increase/decrease the width and length of an object, or use the white box in the middle to increase/decrease the height of an object.

To scale all sides equally at the same time, hold down the shift key and then drag any of the white boxes like normal. Keep the shift key held down until you are finished scaling. If you would like an accurate measurement on one side, start by scaling the model and type in your measurement on a side that you choose.
