Do affordable A2 / C-size scanners exist for CAD and CNC work?

February 22, 2010

Over the years we have received many enquiries from our Scan2CAD raster to vector conversion software users for an A2 / C-size wide format scanner with which to scan monochrome CAD technical drawings and or CNC shapes and profiles.
Most enquirers expect such a medium-size scanner to be affordably priced and widely available. However, typing [...]

At last, more affordable A1 / D-size scanners!

January 18, 2010

A few years back we conducted a survey of our Scan2CAD users to find out what they wanted in a large format scanner. To our surprise, almost half said that an A1 / D-size wide format scanner would meet their needs. Price, as always, was the sticking point. Most wanted to pay no more than [...]

Buying a large format scanner for automatic raster to vector conversion (Part III)

In their advertisements and sales literature the large format scanner manufacturers all claim that their scanners are fast, easy and productive.
We must disagree. We receive hundreds of poorly scanned images every year which are totally unsuitable for raster to vector conversion. Clearly, the people who made these scans did not have a clue. If scanners are so [...]

Buying a large format scanner for automatic raster to vector conversion (Part I)

July 10, 2009

By far the biggest barrier to good automatic vectorization results is poor quality scanned images.
With a good quality scanned image, good results are possible from competent vectorization software. With a poor image, the odds are stacked against a good raster to vector conversion result from the start. GIGO! (Garbage In, Garbage Out).
