The cuttings carried out on the lines of folding are controlled by the entity ''Sketch block''. It is possible to create and personalize its own blocks by observing two conditions:

  • The insertion point must correspond to the point taken for positioning at the end of the line of folding.
  • To comprise one, and only one, line of construction which will make it possible to direct the block compared to the line of folding.

Example:

Creation of a polygonal form of 2mm.


 


At the time of positioning, the tool MarkFoldLines analysis the lines of folding and puts two constraints to position the sketch block:

  • 1st constraint:
    • A parallel constraint enters the line of construction and the line of folding.
  • 2nd constraint:
    • If the line of folding is inside sheet (for example case of the folds with tear), a constraint of coincidence between the insertion point of the block and the end of the line of folding is put.


 


    • If the line of folding coincides with the edge of sheet, a constraint of intersection is put between the insertion point of the block and the edge.
