Drawing Guidelines

DRAWING BASICS

Raster vs. Vector

Our cutting process ultimately requires a defined “vector” based image. If you don’t have vector, we convert it. Vector based images can be scaled without compromising design accuracy and detail. Pixel based images lose clarity when you enlarge.

Raster Raster Graphic

A drawing or image that is composed of a grid of pixels (dots)

Vector Vector Image

A drawing or image that is composed of a series of vectors (lines and curved paths defined by a start and end point)

CAD Drawings

CAD (Computer-aided design) drawings are generally vector type. There are several vector drawing formats, including DWG, IGES and AI, however, DXF is preferred for our cutting process. When possible, please send your drawings as a DXF.

Rastor Graphic Formats

There are several types of Rastor Graphic formats, including JPEG, GIF, BMP, PCX, PICT, PNG, TIFF. If we receive a pixelated drawing, it will have to be converted. This process can be time consuming and may require customer input regarding how best to define the image using vectorized scanning and tracing methods. Resolution (density of pixels) becomes important when sending Rastor Graphic images.

COMMON PROBLEMS WITH VECTOR DRAWINGS

Common drawing problems are often too small to see until the image is enlarged (zoomed) for review.

Over-Defined Over-defined

Over-defined drawings may have lines that intersect and extend beyond the intended part line.

Under-Defined Under-defined

Under-defined drawings have lines that fall short of their intended destination.

Layered Layered

Layered drawings have part features that are identical (or nearly so) that “lay” on or under other existing features (i.e. a line on top of another similar line).
