There is a tool in CooRecorder to measure across a crack - the CrackMarker tool.
The picture above shows two possible paths for measuring across the crack. The upper path
is very precise and it is the method to be prefered when possible, i.e. the old way as described above with
a pair of measuring points.
Though there are cases when you cannot traverse the crack that easy. Then the lower path may be considered!
When using the CrackMarker tool you can set a crackmark point at each side of the crack as shown above. When CDendro reads
the .pos file, it will subtract the width of the crack from the full width of the ring.
The main problem with this method is that it is difficult to see the edges of the crack as the scanner does not
look in right angles towards the wood surface. Instead this picture was obviously taken aslant, as it
shows a bit of the inside of that crack as a light area.
To use the CrackMarker tool, click on its button and it will light up. You can also select it with the M key on your keyboard.
Then click where you want to set the points. When ready, click e.g. the D key (data mode) to continue measuring as normal.
