Hello,

I do not manage to make bevel on object?
Can somebody help me?

thank you

Hi osx59 - that's definitely going to be a difficult model to fillet, particularly around the very sharp concave type corner in the back side area.

I don't think that the edge-based filleter is going to figure out how to build a corner connection piece in that area, to fillet that you will have to do a lot more "low level" type surface modeling. I have attached a model here (ft2_2.zip) that shows the result of some of this, I trimmed some areas back and did a blend to try and make a smooth connection in that corner, and did some surface/surface fillets in a few places. Most of this was done by using Edit/Separate first to break the model into individual surfaces and then work on them.

I hope that might give you some ideas on how to make some progress at least, it will probably be a fairly difficult job.


Maybe it would be easier to get this finished by making one big single surface for the top piece and then cutting a hole for the kind of slot...

Hi osx59 - here is a bit more of a description of the alternate method, this is pretty rough but might give you an idea on a different approach.

To start with I drew several curves like this:



Then I used Construct / Loft to make a surface out of them:



Then extrude that surface to get your volume shape:



Get some 2D curves on the bottom to act as cutters:



Do boolean difference to cut those out of the shape:



Then this has a much fewer number of curves and corners that have to be built, this kind of thing is more easily filleted:



That kind of an approach has a lot fewer pieces involved, that can often times make filleting work better.

Extrude or Shell+trim ?

Hi Pilou - If you look at the original model, it has a kind of "steep"-ness to it, that is the type of thing generated by extrude.

Shell will produce something like this:



That kind of has movement in many different directions, the new surface is along the surface normal of the original shape and not just in one single direction.

Extrude moves only in one single direction, that's more like the original shape.

yes, but the original form is not" natural" and difficult to built in reality and dangerous to use ;)

Thought I would have a quick play.

I made profiles/rails from the shape given,.. added fillets to the profiles, then swept the surfaces.

This last one is more confortable :)

verry good , manz !!!!

Exactly what I wanted to do , can you explain me the progression.

I had tested, but I do not arrive at the same result!

Hello,

You just now need to make a sweep using profiles from the part you have made(with the rads), using rails from the seat part.

Select the back and join the edges for the profile, then select the seat, and copy paste the edges for the rails. Then use sweep.



Just be careful with the rails, you will need to trim/rotate the back rail or you will get a bad blend (the surface will have creases)



Hope that helps, if not, I will post the model and explain more.

Thanks manz

It's verry good solution ..

verry Thanks

Vincent
