Specifications are determined based mainly on "cost," "details," and "scale" that fit the purposes.
The cost varies depending on the degree of details and amount of ready-made supplies that can be utilized.
It is also possible to set a budget and allocate funds accordingly.
Details are important in cases where the interior of a building is of significance or background research is required for a historical building.
The cost becomes relatively high as the number of one-off items increases.
The scale is determined roughly by the scope and size of the diorama, but we recommend scales in which ready-made supplies can be used.
