Redesign the sketch drawings of the parts into technical drawings.

There are 15 ready sketches of parts with specified dimensions. The parts are already being manufactured based on these sketches, so the main dimensions have been agreed upon with production.

It is necessary to convert the sketches into clean technical drawings. As an example of formatting, I am attaching a drawing of a gear.

Scope of work:

• Out of 15 drawings, 3 need to be fully checked: tolerances and fits, roughness, bases, geometric tolerances, and other necessary technical markings. For example, in the attached files "BK left rigid," this is one of four sketches of the bushing; if it is redone, the other 3 are identical and there are also 2 shafts and one wheel.
• If the specified tolerances and roughness on the sketches are incorrect, they need to be corrected or a suitable option proposed;
• The remaining drawings are simpler and mostly identical. They can be formatted by checking the correctness of the markings and the absence of obvious errors.

We would like to receive the result in PDF format.
