Thanks for the advice and examples etc. It really helped me. Thank you so much.

Hi Jeff, I can draw OK with sketchup but it is the complex curves and even wall thickness. In a previous topic (curviloft...) ypou can see the start off attempt but the I cant make it cutrve in the other direction on the face. I was just wondering the best way to go about it. Not ony do I want the face to curve east to west but also north to south.

I am trying to draw this in sketchup but having trouble working out the best way when an object has complex curves that goes in multiple planes.
Below is the object I want to recreate in sketchup. I was trying curiloft but the bottom or face also needs to be curved. It needs even wall thickness also.

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

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

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

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.

Thanks TIG. I did reverse the face but it did not make any difference. As I said, just make a cube and group it and it is soild when you click info. Then remove the top face and then use curviloft on the 4 top edges and it makes the top face. Howver the infor does not see it as a solid.

My shape and a cube that has the top replaced using the curviloft shape skinning plugin. The cube is not solid according to Enity info.

V6 version

When I use curviloft, I can't make the group be recognised as a solid. I draw a cube and then delete one face and then use curviloft plugin to creat the face. It looks solid but when I group it, it is not a sold. I am trying to produce solids with curved surfaces that are quite organic and curviloft works well except the models are not recognised as solid. FIXSOLID or the other solidfix plugins destroy the model.
Any help is appreciated.

Thank you for your quick reply and solution. It works with bigger scale.
