sheet and fold radius

[braunfish]

I would have the need (although in practice the thing cannot practically occur), when I make for example 90° folds in the sheet, that the outer radius equals to the thickness and the internal radius is zero, in practice a right angle.
Is this setting possible?

no you still have to have an internal fold radius at least 0.01mm....
if your problem is on the length of development (i.e. development= sum internal sides) try to change the factor "k" with 0.273

These things do not understand, a folded sheet has a specific fold radius, the cad 3d allows to establish k factors for each fold radius, and to relish the pieces as they will actually, with the appropriate discharges and joints.
it will be that in my company the folds are round, but the fact of obliging designers not to simplify and to have the right developments without the workshop to fold the pieces with unexpected developments.

Clearly you don't understand them, probably because your workshop has different needs from mine.
Imagine having a sheet folded at 90°. the two sides are 50 cm, and the development is 6 meters.
Do you think I might be interested in the inner fold radius? in the cad are only extra lines that bother me.

another question: if I made a piece already bent with a certain factor k, can you update all folds with a different k factor?
Thank you very much.

the k factor is a "general" explanation rule for all the folds of your piece if you want to work in finesse, after making several bend tests with different angles, you can fill out a fold table where at each fold angle you see a different explanation rule.. .
