One more sheet metal question.

Hi.

I have a one more  questions.

In this case, how can it cut out the model like the yellow line?

 

Thanks.

I did try to make the same and  I see the same issue, although when you unfold the part, it is ok.

Hi TJ and Willem,

Is this how you want it to create?

Use only Bend from the Sheet Metal Catalog as it will never work with any other as I have experienced. Open up Setback value as this a tight geometry. Others may have better knowledge than I would.

Thank you very much. Josep.

But,  I cannot get the box to the dimensions I want using the smooth bend alignment option.

I would like to design an exact box using the outbend option.

just tested it and it works perfect!!!

There is no problem with the shape, but it is difficult to make a model with accurate dimensions.

Hi TJ,

What I do is just change my thinking on the stock. With Out Bend, the stock is 400x300, with the Bend there is a difference of 12.5mm (6.25mm offset/per bend - varies on stock thickness used) so I set the stock to 387.5x287.5. I know this quite tedious and annoying, but if you common stocks used, I made notes on this offset per stock thickness. Though it is wishful to have mitre done with all sort of bend features, it made me think and plan ahead. Sort of manual to semi automated thinking.

Hi. Joseph.

Thank you for spending so much of your precious time.
There is no big problem if the externally large dimension is reduced as much as it is increased.
However, in the case of modeling in the red circle, it is inconvenient for the user to do the work by reducing the increased amount after calculating it when modeling.

Thank you very much. Joseph. ^^

Hi tgjang.

There are several other users as well as myself who avoid out-bend and in-bend and just use smooth bends because of the problems you are coming across.

The downside is when you increase material thickness and/or minimum inside bend radius, then your model changes its overall dimensions. The upside is that it keeps your maths skills up.

Hi Jang,

For the same reasons as Harley(sheet metal size box on bend gets weird when changing material thickness with Out Bend, etc..), I'm only using Bend. After months of doing it, I'm able to do decimal addition and subtraction.
