The Library

The Library is useful when you need an element throughout your design without having to repeatedly assemble or duplicate it.

Mockup opens up with more than 100 pre-existing elements under “Mockup Elements” and “iPhone Elements” allowing for quick access and a smooth sketching experience.

You can also CREATE your own elements, save and reuse them for convenient purposes in your sketching process.

It is worth noting that elements in Mockup 3.0 can be drawings, images, text, or a group of them.

How to Create an Element

To create an element for the library:

  1. Draw a selection around the desired strokes and objects in the canvas by using the lasso tool.
  2. Select “Add to Library”

A new dialog with a preview of the element to be saved appears.

  1. Name the element and select the set to which it will be added.
  2. Tap on Save.

Once it is saved in the element library, it can be inserted anywhere anytime.

How to Insert an Element

To insert an element:

  1. Drag any element from the Library.
  2. Drop it where desired on the canvas.

Rename / Delete

Tap and hold on to the desired element to open the context menu, which includes the options Rename and Delete. Same thing for renaming and deleting element sets.

Publish Your Created Elements to the Community

You can easily publish your created elements directly to the Elements Category from the app.

Upon tapping, you will be asked to log in or sign up to the Mockup Community if you haven’t already.

A loading pop-up will appear while the element is being uploaded, and a new topic will be created on your behalf in the Elements category.

Export / Import an Element


Tap and hold the desired element/set then tap export.


  • To import an element from Mockup’s Community Website, tap on the “Import to Mockup” link in any topic in the Elements category. Mockup will automatically open, download the element, and prompt you to select an element set to save it in.

  • To import an element set, tap on “import element set” found in the library. Alternatively, you can open the element set file from the Files app.

  • To import a single element, you can open the element file from the Files app and choose the desired set.
