.net - WPF, xaml Cad or drawing app examples? -

I am trying to learn WPF and xaml and writing a cad-style geometry app for my children. Does anyone know the examples written in the current VB.net? C # OK is also thanks!

Edit:

Any ideas / examples about how to configure any such app? TIA

My first step will be to create a custom canvas that has the capability to keep and maintain shapes. Important part is. Things like grid will need to be transformed on the edges.

Then I will look at the category of shapes that your children can attract, intersections, rectangles, circles, things like.

It is important to decide on a document format because it will partly help you to design some of your code, it would be nice to use XML format for serialization and other things.

Then start building front end, toolbar, etc.

It's a bit difficult to know where it's starting, but I will start with a custom canvas The most important part is and if you can achieve this task efficiently and effectively, the rest will be easy.

Just work on some ideas for you :)
