Standard part corner seam

[benjamin_herinckx]

Hi all,

v: Inventor 2019

Given a n-sided hollowed polygon is there a simple way to remove the corners and be left with only rectangular bits ?

(see attachment)

Something very close is the corner seam function in sheet metal parts. However my parts are generally not sheet metals (not necessarely even thickness) and I don't want to use the concept of tolerance.

I have tried playing around with splits and cuts but can't seem to find what i'm looking for...

Please let me know if you have faced something similar.

Best Regards.

PS : there's a bonus if the bits are left as different solids.

Depends on true Design Intent.

Model as Surface Bodies rather than solid and Thicken each surface as New Body, but that does result in uniform thickness bodies.

Right, of course this needs additional details.

The difficulty lies in that this is the last intended step in a top down design process.

Typically the solid would have additional details such as holes and extrusions.

One of the semi-working approach is the following :

1- copy existing body as surface geometry

2- thicken inner faces into independent solids (implies loss of feature details)

3- sculpt independent solids with the copied surface geometry (to recover feature details)

This works alright except:

1 - The physical properties of the part are skewed because of accounting for the thicken material

2 - The process is very fastidious and error prone

Hi, I don't think it should get so complicated.
If you use the @JDMather  method, then you can use the feature combine, with the "keep toolbody" option until the last complex face with holes in the intersection mode. In this way it maintains the original solid to make all the intersections between solids, and in the end eliminates the original solid.

I hope this helps. Cheers
