Technical drawings with 3D-Printed forms

Many students have difficulty visualizing a three-dimensional body from a drawing. In order to train this imaginative ability, I have developed this teaching unit. Instead of creating a three-plane projection with the help of an isometry, the drawing is to be created here using a 3D body.
All dimensions can be measured from the body and transferred to the sheet at a scale of 1:1. The dimensions are always divided into a 5mm or 10mm grid, so that the measuring is easy.

Solution sheets are also available. These are just one way of drawing the parts, as a front view is not defined. The solutions are created in the projection method 1.
Under each model is a number from one to ten. This matches the numbers on the solution sheets.

There are also drawing templates. If drawing boards are used, it is recommended to use the blank sheets. If only drawing with a set square, the squared paper is to be preferred.

Edit: In the solution Sheet was an error in Part 8.
