Sorry but after a lot of tests of BRepAlgoAPI_Fuse and aBRepAlgo_Fuse the result is:
a lot of INVALID SOLID OPERATION !!!
Please don't say that Opencascade can do boolean operations !!!

Hi !
Well.....it can......sometimes......with some shapes.....not all.....
But the rumour says it has been improved in 5.0, have not found any good reason to try it yet though...

My tests are all under OCC 5.0.
Thank you,

Hi Filippo,
this is the old style, try the new BOP classes!

I use old classes because new classes, like BRepAlgoAPI_Fuse, are not able to join adiacent faces.

Filippo.

My problem is very much the same - but for the boolean section algorithm:
When cutting a shape with a plane the old algorithm (BRepAlgo_Section) returns some edges (I have not checked their validity yet), while the new and allegedly improved one (BRepAlgoAPI_Section) never returns any edges at all.
What may be the reason for it?
Thanks, Reinhold

Hello!
I have the same problem, I try to make a tube whith holes made by smaler tubes that intersect with the first( for that , I take a big cylinder, and I cut it with smaller one, on the same axe to get the tube, and then i cut the tube with radial cylinders to get the holes). OC (4.0,5.0,5.1) forgets edges since the 20th one (amayzing! isnt'it?). I paid to OCC staff (two years ago) for help, and they said me only to enlarge the admited precision of calculation up to 0.001. Finaly I found a solution that work pretty well: I make only one solid with all the cutting cylinders, and cut the external cylinder with this solid. It works and I get all the holes. That's my solution, this is a way to hide jump over the problem, I hope it can help.., but I do not understand why OCC forgets some edges with the first algo......
Best regards to every hard OCC workers!!!
