Either photocopying, photographic techniques, or computer reproduction (scanning) must replicate opaque surfaces Most often used paper surface for sketching in-process design drawings and graphics is. Known all throughout the nation as "trace, flimsy and "bumwad," this paper is quite cheap and transparent. Cut sheets and rolls in a range of sizes abound
with tracing paper. Given the many drawing sizes needed in interior design, rolls of tracing paper are ideal. Tracing paper comes white, buff, and in canaries (yellow). Most designers have a personal color inclination derived from past experience Tracing paper is rather cheap, hence it can be used for preliminary sketches and in-process drawings. This lets one explore
by means of numerous sketches and the development of many concepts. Additionally quite effective overlay on drawings for image transfer and enhancement is tracing paper. Often as a design is refined or as a complex perspective drawing is built, numerous layers of tracing paper are overlaidA diazo print printer allows one to replicate images on tracing paper readily
Photocopied Still it is quite delicate and easily torn and crumpled
This makes it not the ideal surface for a drawing meant for great reproduction Most final design drawings produced manually are made on a transparent paper available in a range of finishes and weights (thicknesses) and most usually white Drafting vellum should have a high rag or cotton content, so providing good stability, strength, and finish. It's great for line work
done using graphite pencils. Drafting vellum originals allows one to run excellent diazo prints. Vellum is also photocopied, scanned, and brilliantly photographed Apart from vellum, PLASTIC DRAFTING FILMS serve both for some design presentations and final drawings. Plastic (and pdrafting films are costly, rip resistant, and normally do not react to temperature
or humidity (as do many paper surfaces). They permit simple ink erasing and receive ink really wonderfully. These films call for the use of special pencils. Original film drafting results in outstanding diazo prints and photocopies. Plastic film and ink drawings were regarded as the best for replication years before CADD was used On vellum or bond drawings, roduction
Film also known as appliqué film and usually referred
to generally as "sticky back is employed. Images typed or printed can be photocopied or sketched onto adhesive replication film. After that, the film is precisely measured, sliced, then placed on bond paper or vellum. Matte appliqué films take pencil nicely; some kinds are repositionable but others are not. While RayvenTM creates a range of films for low-, medium-,
and high-heat copiers, high-heat photocopiers can cause buckling of some appliqué films Manual drawing usually calls for tracing paper, drafting vellum, and drafting film. Although they cannot be layered and do not re-produce well, non-transparent papers such fine art drawing papers can be used with outstanding results. Transparency sheets are ideal for the
nature of the design process, which calls for ongoing exploration and modification Design drawings are currently replicated using large-format photocopying. m <In interior design drawings and models, lines and marks log spatial information.To create what are often known as "lead," graphite is combined with clay and other materials. Used in design drawing,
Graphite pencils come in a spectrum of hardness depending
on the clay to graphite mix Standard rating systems for graphite pencils and replaceable leads" indicate the degree of hardness. A 6B, for instance, is softer than a 2B; an 8H is somewhat rigid. F-rated leads lie in the middle of the range; HB leads are somewhat harsher than Bs. While H, 2H, and occasionally F leads are most usually utilized in drafting, sketching
and rendering require the softer leads. Often graded differently than graphite leads, polymer-based leads used on plastic and polyester drafting film Many mark-making tools make use of the graphite discussed above. Made from a graphite combination wrapped in wood, WOODEN DRAWING PENCILS are sharpened like ordinary wooden writing pencils.
MECHANICAL PENCILS are hollow tools featuring very fine graphite leads. These are offered in several lead widths to produce a range of line weights Hollow tools designed to accept thicker leads than mechanical pencils called LEAD HOLDERS. Lead holders tolerate a range of lead kinds in terms of softness even if they do not let any variation in lead widths. Lead
Conclution
holders need a specific sharpening called a Before hard-lining a drawing, one might develop it with specialized colored drafting pencils and leads. Although they occasionally reproduce when photocopied, non-photo-blue colored pencils cannot be photographed. Diazo prints do not faithfully replicate NONPRINT colored pencils. Drawing layouts before completion can be done with both kinds of pencil depending on need Using graphite pencils has one major
benefit in that erasing is simple. Usually, harder leads are the most challenging to remove graphics. Important and transmit particular information are control of line width and the kind of stroke applied Design drawing thus depends much on the implement used to produce lines and marks.Germany.
