Next step is to create the 'holes' in the B. This will be a review of the procedure used to subtract a shape from letter A, but this time we need to make 2 holes!
Deselect the B shape. Create new circle shape.Ellipse Tool
Colors: Black outline. no fill.
Tool options: Circle shape, Show Nodes, Create on Vector, Line Style Solid, Width 3, Anti-Alias checked.
Draw 2 circles in the of B for the 'holes'. Make the bottom 'hole' slightly larger than the top one.
Shape Tool: Select top circle, right click, select 'Convert to Path'.Switch to...
Pen Tool-Edit mode: Right click, Edit>Select All
Pen Tool-Edit mode: Right click, Edit>Reverse Contour
Pen Tool-Edit mode: Right click, Edit>Cut
Pen Tool-Edit mode: Select colored B shape (nodes should be visible), right click, select Edit>Paste. The 2 shapes are now combined and one 'hole' has been subtracted from the B.
Repeat for the other 'hole'.
Shape Tool or Pick Tool: Select bottom black circle, right click, select Convert to Path. Switch to...
Pen Tool-Edit mode: Right click, Edit>Select all
Pen Tool-Edit mode: Right click, Edit>Reverse Contour
Pen Tool-Edit mode: Right click, Edit>Cut
Pen Tool-Edit mode: Select colored B shape (nodes should be visible), right click, select Edit>Paste to subtract 2nd shape.
On the B layer of your Layer Palette, there are now 2 sub-layers named 'new ellipse' that are blank. Again, for sake of neatness, remove these sub-layers by right-clicking the layer on Layer Palette and selecting 'Clear'.
Now the shape looks more like a B, but it probably needs a little fine-tuning. Use the Pen tool to select nodes and adjust control arms to smooth the curves until B looks more like finished shape above. I think the B looks better if bottom half ('belly') is larger than top and holes are aligned.
Tip: Don't make the 'holes' too big or B won't look like a chubby bubble!
To move or resize the 'holes' in the B without distorting the circle shape, select all 4 nodes of the circle first. Either drag a selection around the circle with the Pen tool or hold down the Shift key while selecting each node with cursor.
Deselect B. You can also hide visibility for B layer now. Click the 'eye' icon on Layer Palette to hide.
