For some unknown reason i keep getting a "All faces are used twice error" during a lofting solids command. If i'm using it on two test solids it all works fine but on a specific solid i'me made I keep getting this error. Already re-drawn the whole thing and re-tried it several times but i'm still getting this error ?!?!

Complete error message: "All faces are used twice. (Is this an open shell?):Lofted Solid_599785"

Using viacad pro v10.0.4

I've added an test vcp file with only two solids (The complexer one is the one that is generating the error)
Hope someone can help me out why this is happening ?!?!?

I believe, there is something going across.
With a new cuboid it does run but asymetrically.

I changed the irregular solid to surfaces and extruded the face to recreate it, then the loft was successful. So, something in its creation?

There's command called check object. That will tell you what might be wrong as in this picture attached. It even has a repair button. I'm not sure if your software has it.

Once the command repaired it, I can loft without any issues.

Wow that are a lot of comments on my question. Love to see so much people using this program and willing to help others :)

The strange thing about the whole thing is that when i've used it the first time, everything went just well (See first.png picture). The problems began when i wanted to change some measurements and did a total redraw on the object. For some reason now i cant seem to get it working again.

The example file i've added with the last post was off-coarse just a simplified test. Not going to loft such a solid with a cube :) Lofting that same cube with the other solid seemed to work just fine so i concentrated on that other part what was in the example.

I've tried my original design again (See new.png picture) and matched the number of vertices of both objects i wanted to loft. But no result. I even checked the extruded solid for errors and although it had some (Strange as it was just generated out of a outline) i wasn't helping the lofting problem. See NewError.png picture.

Murray, How did you create a surface from that solid and then turn it back to a solid again? I've tried to create a surface from that solid but i don't seem to manage to creating a solid again from that surface?

I've added a new example vcp file including the both outlines from where the solids where created. I left in the error on the right solid so you maybe can see the difference with the left one. For some reason the left outline isn't generating a solid with errors while the right one does.

I guess something is wrong with the right outline but i can't figure out what ?!?!?!

Thanks in advance.

I've tried it again on my second example and indeed it seems to work in this simple file. Tried again on my bigger design (Where this is a part of) and it fails. Tried copying those two parts out of my bigger design to the example file and it still doesn't work.
After i've copied the repaired solid that was in my second example back to the original design, it seems to work.

Maybe someone can figure out why that outline was generating errors in the first place?

Right-click on an object and you'll see "change object type" in the context menu. Click on it and you get a list of options of what type you can convert to. Solids into surfaces gives you the faces of the solid. I deleted all except the profile face and the bottom edge, I extruded the profile face and the bottom edge gave me the extrusion length.

Ok, like that, great :)
I've used the change object type before but not really on solids, thanks for the info.

Beats me! I don't see any errors in the curves. I have come across that issue before. When the repair command fails, all I do is break the solid into surfaces and restitch into a solid and that fixes the solid of errors.
