Unleash your creativity with the new pen tools
Fountain Pen allows users to make thinner lines and detail lettering. You can use speed and pressure to control the thickness of your writing.
Brush Pen is directional based allowing users to create artistic letters with minimal efforts. With the brush pen, the thickness updates automatically with direction of the stroke. 
How it works
-
The fountain pen and brush pen are automatically added to your draw tab. If not, you can add the pen by selecting Add Pen.
-
After the pen is added to your draw tab, try out the different pen thickness and colors. You can define your own inking palette for the pen by selecting More Colors or using the Eyedropper tool!
Tip: Right-click on the selected pen to open the pen menu where you can delete any pen and then use the Add Pen button to a new pen.
