I am in the middle of making a walnut corner cabinet. There is some
dimensioned sketches provided and a bill of materials . I t is a beautiful
cabinet adn the author has attempted to give every dimension to ensure a
perfect copy can be made .
This is a difficult task, resulting in the inevitable mistakes in some of
the dimensions ,as much as 5" inches in some cases .
So here is a suggestion that I use to precheck the dimensions provided,
given that the sketches are to scale .
Take the sketch and scan into your imaging program . I usually scan it in
greyscale and then enhance the scan by increasing the contrast .
Now crop the area you are interested in [say a door assy], crop it exactly
to one of the given dimensions , then size the scanned image to the exact
size of the dimension cropped to for printing .
The result should be a to scale print that can at least be used to double
check the written plan dimensions ...
