line relations that cannot be added

Hello, i am trying to build a box and i am trying to make a flat layout like nesting of the box, that will modify parametric.

i am trying to do that by adding line relationships to the base model. But i am at a problem some relation cannot be added.

Anyone knows a work around? Equations that not apply,becouse most of the demensions in the model are driven dimension.

Please if you can help whit a tip.Thanks

What relationship do you want to add between the selected lines?

The software is only showing the relationships which make sense between two lines. If you selected different sketch items (i.e. arcs, or points), you'd get a different selection of relationships to choose from.

You could look at Global Variables. But I'm not sure they would help as it is unclear what the goal is.

May be you want to work with Sheet metal. the generate the Flat pattern to cutt it / bend it / weld it !

The relationship between the horizontal line and that of the other sketch is possible because some points are on the same plane. Which is not the case of the vertical line. Maybe a 3d sketch would help you.

the 3d sketch did it for me. THANKS ALOT
