Zusammenfassung:Drawing stencil for circles and radii with radially movable circular plate with scale subdivision from R15 to R50 and with hole distances every 0.5mm of different hole diameters as well as with a division into angular degrees. The stencil is made in varying sizes covering the ranges R15 - R50, R50 - R80 and R80 to R120 with the material made from transparent plastic. The different hole diameters are incorporated to enable different drawing instruments to be securely guided by the stencil during drawing operations. The stencil rotates the instrument around the planned centre point without leaving a centre puncture.
