Technical drawing tools

Exhibition of the most important and useful technical drawing tools in the history of architectural design: compass, circlesometer, graphos, rapidograph, goniometer, drafting machine, scalimeter, drawing templates, normographs, squares, drawing boards, etc.

Scale ruler

by Archweb .com

The Scale ruler is a ruler with a triangular section that shows a different graphic scale on each of the six sides. Through the graphic scale of reference it is possible to read the real measurements on drawings and projects.

Drafting machine

The drafting machine is a technical drawing assistance tool composed of a square (or pair of rulers bound in an orthogonal way) mounted on a protractor that allows its angular rotation.

Set square

Guide masks for technical drawing

by Archweb .com

Drafting or furniture templates appear when standard symbols are to be drawn "by hand" and repeatedly. The most common model is flat plastic with the standard symbols cut out inside.

Slide rule

by Archweb .com

The slide rule exploits the properties of logarithms, tracing more complex operations (products, quotients, exponentials) to simpler operations on the logarithms of the respective operands.

Lettering guide template

by Archweb .com

The stencil is a particular type of ruler, used for writing uniform characters. It consists of a sheet of plastic or other material with carved letters of the alphabet or other useful shapes, particularly for technical drawing.

Protractor

The hatch graph is a technical tool for drawing parallel lines at regular intervals. It is a sliding ruler connected to a vertical rod which, through a small push-button device, allows it .... >>

French curve

by Archweb .com

Drawing templates, circles, curvilinear ellipsometer and other geometric figures are used when the standard graphic must be drawn "by hand" repeatedly.
