Reliable 1:1 scan software?
Reliable 1:1 scan software?
(OP)
Hello,
I'm trying to figure out how to scan a sketch at real 1:1 scale, to be able to reproduce the geometrical elements as detailed as possible in a CAD sketcher. For example, if I "copy" the geometrical form of an object (just do the trace of the profile with the pencil on a paper sheet), I would like to be able to scan the profile on the paper at 1:1 scale, in order to sketch it in a CAD sketcher with the highest possible accuracy. Could somebody point me to a good and reliable software which will do the (scan) job with a normal (consumer) scanner?
Thank you very much in advance for your answers!

If you want accurate then something like:
h
may be better - or a lot of time in a CMM machine.
Even then, you'll have only measured one unit most likely and don't know how that one varies from the mean...

RE: Reliable 1:1 scan software?
Having said that, my own experience is that unless you have a really first-class scan, and a very high quality original image, many of the automatic raster-to-vector software will typically generate output which will need quite a bit of manual cleaning up. (E.g. scanning artifacts will be translated into short lines or vertexes; lines which appear to meet on paper may or may not intersect at a common vertex in the CAD version; etc.) Manually "tracing" a scan in the CAD package of your choice can often be more productive in many cases.
Hope this helps!

AutoCAD has a really good raster-to-vector conversion tool.

Paper, afterall, is subject to moisture and thermal changes. Ask anyone who has ever plotted a drawing (scaled) and then went back to the paper plot with a scale.
