|Axis follow the STL convention, all dimensions are in mm.|
The basic principle is that Z=0 portions are not visible.
Draw the outline of the shape using the selection tools, then give it Z volume by using the shape tools.

Shape tools hints:
The Tilt Shape Tool
is very useful in creating reinforcements.|
Use Shift to constrain tilt to X or Y axis..
To use the Folding Tool
First draw a rectangle with only one edge crossing the shape.
This determines the fold line.
Order of folds is important. Always start from the outside of the shape.
Use the Folding Tool with Shift to modify Z from folding line.
Drawing with negative Z is possible by selecting the corresponding|

For easier scaling, you may first position your image on the below build plane using an image editor.
This build plane is 1000 x 1000px for a print dimension of 100x100mm (1 pixel = 0.1 mm)

Requires active rectangular selection, with only one edge crossing the shape.
This edge defines the folding line. Z from folding is maxZ/2, maxZ being maximum
