Main Parameters

 
Name: Description: Used in/Using parameters: Default expression (mm):
L Defines the real length of the box, depending on the dimension type ( DT ). However, the actual length of the base in the drawing is calculated by taking into account not only L, but also DT and FD,and is measured through the Lss and Lss1 parameters.

L is only used in the expressions of the actual score-to-score length parameters Lss and Lss1. This means that changing the expression of L will change the length (Lss and Lss1) of the current resizable design, too.

W Defines the real width of the box, depending on the dimension type ( DT). Just like  L, the actual width of the base, in the drawing, is calculated by taking into account W, DT and FD, but it is measured through both Wss and Wss1 parameters. The difference between Wss and Wss1 stems from the fact that Wss1 takes into account only one folding. W is used directly in the expressions of the score-to-score width parameters Wss and Wss1.

W is only used in the expressions of the actual score-to-score length parameters Wss and Wss1. This means that changing the expression of W will change the width (Wss and Wss1) of the current resizable design, too.

H Defines the realheight of the box, depending on the dimension type ( DT ). However, just like the L and W, the actual height of the base in the drawing is calculated by taking into account not only H, but also DT and FD, and is measured through the Hssparameter. Used In:
Hss

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 DimTypes 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 rensions 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 he two side flaps, which, when folded at 90o, "eat away" d/2 each ).
