Paper Drawings
Paper Drawings are most common type of drawings. They were invented centuries ago. Their functions are:
Information storage.
It is perfect way to store graphic data - paper drawings last centuries. Information storage is main function for paper drawings.
Design media/source
Characteristics of Paper Drawing
1. No need for special hardware and software (Strong point)
2. Simple to make them legal (signed) (Strong point)
3. Well-educated person needed to retrieve most of information (Weak point)
4. Not easy to modify (Weak point)
CAD Drawings
It is a modern type of drawings. Their functions are:
Design media - as primary function.
Information storage - as secondary one. There are too many proprietary CAD drawing formats. It causes inconvenience to store
graphic data in CAD format, because it will lead to difficulties with distribution. Lack of standard de-jure compensates by
appearance of standard de-facto (DXF file format)
Characteristics of CAD Drawing
1. SW and HW dependent. (Weak point)
2. Difficult or nearly impossible to make it legal. (Weak point)
3. Extremely fast and precise information retrieval. (Strong point)
4. Easy to modify. (Strong point)
Raster Drawings
What are they? They are "Digital Paper".
Characteristics of Raster Drawing
It is a modern type of drawings. Their functions are:
1. Less SW and HW dependent. (Strong point)
2. Simple to make them legal (signed). (Strong point)
3. Well-educated person needed to retrieve most of information. (Weak point)
4. Not easy to modify. (Weak point)
Raster weak points:
- Speed and precision of information retrieval
- It is needed well-educated person to handle information of drawing (mechanical engineer, architect, etc)
- It is difficult to measure and calculate on base of raster data (distance, area, coordinate, etc)
- Modification ability.
Have you ever try to change diameter of circle in traditional raster editor?
Intelligent Raster Drawings
"Intelligent Raster" is a perfect combination of strongest points from Paper Drawing and from CAD-file. New
generation of products by IDEAL.com brings Intelligent Raster to life.
IDEAL.com's WiseImage products have capabilities to "recognize" objects on raster image. When user picks a point on a raster,
software finds out what kind of an object user pointed to. All object's properties can be retrieved immediately (for example,
Length of line or arc, Width, Area of closed polyline, etc). From user's point of view it seems, like raster image contains
the same objects as CAD-file. No raster-to-vector conversion is needed to modify a raster drawing with usage of typical CAD
tools, e.g. to find and replace objects, to change object's properties, etc.
New hybrid graphics has enough power to eliminate need for raster-to-vector conversion of scanned images in most cases.
Characteristics of Intelligent Raster
1. Less SW and HW dependent. (Strong point from paper)
2. Simple to make them legal (signed). (Strong point from paper)
3. Fast and precise information retrieval. (Strong point from CAD)
4. Easy to modify. (Strong point from CAD)
Leave CAD for designers and creators, other users of drawings will have enough with WiseImage Intelligent Raster and Hybrid
