Engineering drawing shares some traits with artistic drawing in that both create pictures. But whereas the purpose of artistic drawing is to convey emotion or artistic sensitivity in some way subjective impressionsthe purpose of engineering drawing is to convey information objective facts. Engineering drawing uses an extensive set of conventions to convey information very precisely, with very little ambiguity. Relationship to other technical drawing types[ edit ] The process of producing engineering drawings, and the skill of producing those, is often referred to as technical drawing or drafting draughting although technical drawings are also required for disciplines that would not ordinarily be thought of as parts of engineering such as architecturelandscapingcabinet makingand garment-making.
Modern[ edit ] The main modern types of pens can be categorized by the kind of writing tip or point on the pen: An inexpensive Bic Cristal ballpoint pen A ballpoint pen dispenses an oil-based ink by rolling a small hard sphereusually 0.
The ballpoint pen is usually reliable and comes in both inexpensive and expensive types. It has replaced the fountain pen as the most common tool for everyday writing. There are certain ballpoint pens combining multiple colours in a single barrel; the writer or artist may depress the tip with the desired colour.
A luxury ballpoint pen A rollerball pen dispenses a water-based liquid or gel ink through a ball tip similar to that of a ballpoint pen. The less-viscous ink is more easily absorbed by paper than oil-based ink, and the pen moves more easily across a writing surface.
The rollerball pen was initially designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen.
Gel inks are available in a range of colors, including metallic paint colors, glitter effects, neon, blurred effects, saturated colors, pastel tones, vibrant shades, shady colors, invisible inksee-through effect, shiny colors, and glow-in-the-dark effects.
Refillable rollerball pens have recently become available using cartridges of fountain pen ink. A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a "feed" to the nib, then through the nib, due to capillary action and gravity.
The nib has no moving parts and delivers ink through a thin slit to the writing surface. A fountain pen reservoir can be refillable or disposable; the disposable type is called an ink cartridge.
A pen with a refillable reservoir may have a mechanism, such as a piston, to draw ink from a bottle through the nib, or it may require refilling with an eyedropper. Refill reservoirs, also known as cartridge converters, are available for some pens which use disposable cartridges.
A fountain pen can be used with permanent or non-permanent inks.
A felt-tip penor markerhas a porous tip of fibrous material. The smallest, finest-tipped felt-tip pens are used for writing on paper. Medium-tipped felt-tips are often used by children for coloring and drawing.
Larger types, often called "markers", are used for writing in larger sizes, often on other surfaces such as corrugated boxes, whiteboards and for chalkboardsoften called "liquid chalk" or "chalkboard markers".
Markers with wide tips and bright but transparent ink, called highlightersare used to highlight text that has already been written or printed.
Pens designed for children or for temporary writing as with a whiteboard or overhead projector typically use non-permanent inks. Large markers used to label shipping cases or other packages are usually permanent markers.
A gel pen uses ink in which pigment is suspended in a water -based gel. Gel pens can be used for many types of writing and illustration. Gel pens often come in bright or neon colors.
A stylus penplural styli or styluses,  is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery.Media in category "Rotring" The following 19 files are in this category, out of 19 total.
