# Drawing Panel

![Drawing Panel](/files/ULHStluzNgWhrnExoBE8)

Drawing panel allows users to design their ideal structure by drawing. The drawn graph will act as a weighting diagram to influence the four optimizers. A detailed introduction to the drawing system can be found [here](/ibeso/tutorial/scoring-system.md).

### Operations

Move the mouse into the canvas, the pointer will become a brush stroke. The pixels in the stroke can be weighted.

Left Click: weighting pixels 

Right Click: erasing weights

Shift+Left Click: drawing lines
