Cant make solid with curviloft

[MAGICMAN]

Thanks Pilou, Exploding the cube and expoloding the top face and then regrouping it fixed the cube. However the other shape I could not fix. . Thanks TIG, I have posted the SKP in the previous post.

Internal faces as TIG suspected also prevents your group from being solid.

Thanks guys for your prompt help. What did you do to fix it Dave?

[gilles]

Look at this:
(note: I just hide the top face)
Also orient the faces.

Wow thanks Gilles, that really helped me. Thanks to all for your help. Much appreciated.

[Dave R]

I just deleted the internal faces and unneeded edges. Probably what gilles showed.

[TIG]

There are two unneeded internal vertical partition faces and a curved surface 'top', which form the 'internal' parts of the end 'wall' and these need removing.
Edit the group.
Temporarily hide the front wall's face; Select and Delete those three faces/surface, then erase the two faceless edges that are left over.
Unhide the wall's front face.
Exit the group-edit.
The group is now a 'solid'.
Easy as that.
Solid-Inspector shows the problem straight off.

Thanks Tig. I loaded the Solid Inspector plugin. It worked great. Thanks again.

A 'solid' object is shown 'solid' in Entity Info...
If it is not a 'solid' then use thomthom's 'Solid Inspector' to see the issues...

Ensure that the to-be-solid group/component contains nothing except edges and faces, and that all of those edges have exactly two faces.
So it can never be a 'solid' if it contains :
nested subgroups.
nested subcomponent-instances.
faceless [lone] edges.
holes in surfaces - no matter how tiny >> edges with one face.
flap-faces >> edges with one face.
internal-partition-faces >> edges with three or more faces.
shared-edges - by two otherwise separate volumes e.g. two cubes touching along one shared edge >> four faces on that edge.
overlaid-faces >> more that two faces per edge [this is possible with some weird geometry, where two faces are all-but coincident [and so appear as one face] but an edge can actually have three, not two faces].
any other objects [although guide-pints/guide-lines are allowed].

Many of these issues are easily fixable:
by exploding nested objects [so you only have edges/faces].
over-drawing edges to form missing faces [healing holes etc].
selecting unwanted edges/faces, then pressing <delete>.
using a section-plane to see its internal geometry, so that you can delete it as needed.
temporarily grouping some geometry to move it apart, e.g. if there is a shared-edge - remember to explode that group when you are done...

With curviloft, you will most probably get a group which is separated from the contours (and their "fillings") therefore it must have holes at the two ends. Copy/paste (in place) those ends into the "curvilofetd" group.

(Or post your model, too, so we can have a look).
