Humidity is one of the most important factor, which in fluence on many wood properties include size. Changing size base on humidity is called shrinkage. It should be considered during the optimizing process in form of different sizes for sawing and invoicing process.
Allowances are defined separately for each size of wood. For this purpose is used . However, it is not necessary to enter all allowances for all sizes of produced timber because if the specifed size is not found here it is approximated from the others. However, it is recommended to enter as much data as you can here. It will increase the precision of calculation.
In this screen is possible to select multiple rows of data and copy them into another species. Select multiple rows you can either by Shift for range selection, or by Ctrl for select/deselect particular rows.
After selecting one or more rows you can press:
Ctrl + C , Ctrl + Insert - Copy selected row/s to clipboards
Ctrl + V , Shift + Insert - Insert selected row/s from clipboards to selected species. In case of existing row, it will be replaced
Delete - Delete selected row/s
If you want to enter some allowances, you must define wood species itself for first. By using top combo-box you will select wood species and then you will define allowances for it. Note, that for specified species can be size defined only once with one allowance. As it is written on window you will define shrinkage allowance for nominal size. (Humidity and allowances can be various depends on wood species. )
