Hello Bruno,

attached is a file with the generating curves, I have used. The magenta curves was used to place the profiles. After placing them, I made a copy and joined them together again. The joined curves I rebuild -> select them all - press the tab key and type rebuild - standard tolerance 0,01. After that I've used two of them as rails for each sweep. If you can't join the results together, there is a trick. Select them all and scale them down by a scale factor of 0,01. After that press join without to deselect. After that scale them up with scale factor 100. So you get back your surfaces joint. The scale down lowers the gap between the surfaces under the threshold of what MoI accept as coincident means 0,005 units!? The connection information will not be lost while scaling up back. Have a look if the method used here works for you, if not I can't help.


Have a nice day
Karsten
