Experience I've been in the 3D/2D CAD industry for 10 yrs. & also had the opportunity/exposure to operate with several mainstream design packages. I've assisted many firms facilitate their 3D migration process.
Question QUESTION: Respected Sir
I am a collector of
coins. Many times a coin
is minted with different
Die Variations. These
variations may be also in
terms of different sizes
of Alphabets and
different sizes of
images. Whether CAD
may eable me to findout
measurement in terms of
mm of the Inscribed
Alphabets and images on
the coins.If so, please
indicate the method.
regards
som
ANSWER: Som, just about all mainstream cad platform can accomplish this. All you need a hi-resolution image of the coin & import this image in Autocad or Solidworks. Find actual/physical diameter of coin at highest precision using a micrometer. Use this number to 'rescale' imported image (diameter) in mm. In Autocad, precision can be measured up to 0.00000001 mm.
In theory, by just referencing the coins diameter precisely as posible, you should be able to interpolate any other dimensions (images/alphabets) inscribed on the coin by using simple distance queries in the software.
Hope this helps!

QUESTION: RESPECTED SIR
I DO NOT REQUIRE HIGH PRECISION.MY PURPOSE IS SOLVED IF I GET MEASURE MENT OF ALPHABETS AND IMAGES WITH AN ERROR OF PLUS MINUS .1 mm.
I AM A NOVICE.PLEASE SEE IF YOU CAN SIMPLIFY THE ANSWER.

Answer Som, what CAD platform are you planning on using? Basically, this is what were doing:
*gather some physical data of coin as precisely as possible
*you need a scanned image of the coin
*import the image in CAD
*resize image based on data collected (using diameter or any reference points you can physically/visually dimension using a caliper). This is the most important part of the process.
Once image is resized, you can use any of inquiry tools in CAD to find your distances by picking points of the alphabet or images.
Hope this helps.
