08. Undo and Eraser

When drawing lines, two frequently used commands are ① Undo and ② Redo. When you create a new canvas, the ① Undo and ② Redo buttons are both greyed out, but as you start to draw those commands will become available. As opposed to drawing on paper, you can delete the line that you have just drawn with one tap if you don't like it, and there are no dirty traces as there are with an eraser. If you're not used to using the app it may be hard to draw the line that's in your head but that's the same for everyone. Practice and you'll gradually be able to draw what's in your head. Keep at it, and make use of undo to get it right.
After drawing ten lines, you can tap the Undo button ten times to return to the original state. If you tap too many times by accident use the Redo button to move forward one step at a time to your preferred state. Undo can also be used for changes to layer order, changes to layer opacity, clearing layers, deletion of layers, creation and clearing of selections. If you make a mistake and clear a layer don't stress - use Undo to move back a step.

Using the Undo command after drawing is OK, but when you want to create clean joints between lines you should try the eraser.
Choose the ② Eraser from the ① Tool Selection window.

Next, open the ① Eraser Properties window.

The Eraser Properties window is just like the Brush Properties window. The only difference is the preview window at the top. The pre-defined brush patterns are the same. The patterns that you will use the most when using the eraser are the Pen (Soft) and Pen (Hard). This time, let's select ① Pen (Hard), ② 16px (pixels).

Next, let's zoom in on the joint and clean it up with the eraser. The important thing to remember about the eraser is that it is returning the layer to a transparent state. It may look like it is turning it white but that is only because the layer below the current layer is white in this case.

When doing a line drawing it is common to hold both the Dip Pen and the eraser at the same time. You can use the ① Brush/Eraser Toggle button to change between the Brush tool and the Eraser tool with one tap.
Drawing by tracing is good training. At first your lines may not go where you intend them to. People often say that their fingers are too big or that they can't see where they are drawing but the majority of people who post images to ibisPaint are using their fingers. If you practice you will definitely improve.
