## Sketching a final project

The [project](../final_project/final_project.md) idea came from 2 people from our local Hackspace (thanks :]) and so I sketched it with [LibreCAD](https://librecad.org/).
It's easy to learn and a nice CAD for technical 2D design.

### LibreCAD


Nice things to note:

#### Selecting methods
::::{grid} 2

:::{grid-item}
![Blue](../_static/blue_select_cropped.png){align=center width="100%"}

Blue selection
:::

:::{grid-item}
![Blue Selected](../_static/blue_selected.png){align=center width="100%"}

After blue selection
:::

::::

::::{grid} 2

:::{grid-item}
![Green](../_static/green_select_copped.png){align=center width="100%"}

Green selection
:::
:::{grid-item}
![Green Selected](../_static/green_selected.png){align=center width="100%"}
After green Selection

#### Editing
::::{grid} 2
:::{grid-item}
![No Text](../_static/no_text.png){align=center width="100%"}
:::
:::{grid-item}
When working, I spend many searches to find out, why no text is shown. Turns out, that when in draft mode, no text is shown for performance reasons. So i need to deactivate draft mode to see text:

![Draft Button](../_static/draft_button_librecad.png){align=center width="50%"}

:::{card}
Working with commands is also very nice, especially when using the relativ point with `@`:

![Command Button](../_static/working_with_librecad.png){align=center width="100%"}

Meaning draw a line from point 10,10 to 20,10 and then a line relative from 20,10 (which is currently the 'relativ point') add @10,20.
So the new endpoint is 20+10,10+20==30,30
