DT Defines the dimension type: inner (dtID = -1), outer (dtOD = 1) or score-to-score (dtSS = 0). Since the material ( board ) of corrugated boxes is by industry standards significantly thicker ( e.g. d=7 mm ) than folding carton boxes material ( most commonly d=0.5 mm ), there occur considerable differences between the "interior" dimensions of the closed FEFCO box and the "exterior" ones. This happens because creasing and double-creasing add to the outside volume of the box. Therefore, you can choose among 3 dimension types to calculate the design, depending on which box size you are interested in: the 'inside' of the box (e.g. when your primary concern is the article that the box is designed for), the outside of the box ( e.g. when you are interested in the outer limits of the box so that you can fit a number of such boxes into a bigger container), or the score to score size (e.g. the in-between dimension type where the system calculates the design without taking into account the value of d; for instance, the real box length parameter Lss has the expression L+2*C90 - i.e.the length parameter L value plus twice the value of the correction parameter C90 which is equal to 0.00 when DT=dtSS, a positive number when DT=dtID, and a negative number when DT=dtOD).

DT is a selection parameter - it uses the selection entries of the Dimension type selection type, ,predefined in the Corrugated parameter template. The 3 predefined entries are as follows:

  • dtID - inside dimension type. Use this dimension type when you seek to define the dimensions of the interior "compartment" of the folded box. The system automatically resizes the whole design according to the specific corrections for inside dimension type, taking into account the additional distances caused by the folding sides of the box. As a result, inside dimension type makes the box design larger than with the other two options ( e.g. although the real length of the interior folded box compartment will be equal to the value of L, Lss has a bigger value than L because the system has to provide for the area that is "eaten away" on folding due to the thickness of the material ).

  • dtSS - score-to-score dimension type. Use this dimension type when you are not concerned with the thickness of the material ( flute ) and you do not want the system to take it into account when calculating the design ( in this case L=Lss ).

  • dtOD - outside dimension type. Use this dimension type when you want the dimensions you enter to define the outer shape of the folded box. The system automatically resizes ( "shrinks" ) the design so that the real outer dimensions are as specified by you ( e.g. the outer length of the folded box is equal to the value of L, and Lss equals to L+d to allow for the "lost" area of the two side flaps, which, when folded at 90o, "eat away" d/2 each ).

To change the expression of DT, click in the Expression column field of DT in the Parameters tabular pane tab and select the desired option from the list.

- dtID
UL Defines whether to use layers (relative to the number and the type of the flaps). If you imagine, that in the current design, each two opposite side flaps form a layer, then the other two opposite ones form another layer that overlaps the first one. Therefore, if the number of the layers is n, you have to apply 'n-1' corrections to the sides adjoining the respective flaps (layers). Of course, the Layers Parameters take into account all these corrections.

UL is a selection type parameter - it uses Boolean selection type , predefined in the Corrugated parameter template. The 2 predefined entries are as follows:

  • Yes - use this type when you wish to use layers, ie. whwn there are overlapping layers (flaps, tucks and etc.)the system to take it into account when calculating the design ( in this case L=Lss ).

  • No - use it when you do not have to use layers or the corrections may be neglected.

To change the expression of UL, click in the Expression column field of UL in the Parameters tabular pane tab and select the desired option from the list.
