I figured it out.....I had an extruded-cut through the lofted bend in
the folded state. Since that cut was there it gave an error for a cut
in the unfolded state.

```Is it possible to create a dimple on a lofted bend part? The lofted bend is
created from two 3d splines so the shape is pretty complex. The forming
tools need a planar face which is not present on the part. Any other way to
do this dimple?

Thanks

```im guessing that when sp4.0 came out. they have added a fixed face
requirement. my lofted bend does not have any flat face or edges. this
new requirement makes the command un-usable to me.

```Hello,

I'm a new user of solidwx. I've got a problem with the bending tables,
working with the loft feature in sheet metal mode.
I've just prepared my excel work sheet, and I tried to work with it.
When the cad asks for it, I tell the directory (my docs) where it is.
But the developed lenghts are still wrong.
For example: for a cylinder with a diameter of 1000 mm, I get a devoloped
lenght of 12000 mmm.
To be complete, the equation I used is:

Lb = alpha ( R + kT )

where:

- alpha is the bend angle in radians
- T is the sheet thickness (usually bigger than 8 mm)
- R is the bend radius
- k is a costant value.

Are there other equations to describe and get the correct lenghts?
Where is my problem?

Waiting for a positive reply, thank you very much.

Vanessa
