how to curve a solid

[thanhlt]

I'm trying to design a curve chair back, I can only make it in a flat shape, please see pic: http://thanh.my-php.net/forum/viewtopic.php?f=19&t=59&sid=8dd7a1d9270cd2960d67793dca4e6b9a .

The left solid is my chair back, is it possible to make it curve like the right solid?

 

Thanks in advance

I don't think to be possible to curve an existing solid entity. Please check if the solution from this previous thread is useful for you.

Thanks so much, I don't know why I cannot see my post, let me show my project again:

Please show me how to make the chair back (the left solid) curve like the right solid.

This is the chair I'm trying to draw the chair back:

Curve an existing solid? I suppose it depends on what you mean exactly. Bend it?

[MSasu]

ReMark, I think that OP's message was retained for moderation due to a link - he/she was looking to create a part for a curved chair.

Hi Msasu

 

Yes, I want to create a part of a chair back, 'cause working for a furniture factory, but I think that autocad cannot bend a solid with an arc, I just want to ask you if there is another way to do so, as this's beyond my reach. I don't want to use pro engineer, solidworks....

 

By the way, could s.o tell me why I cannot see my post

 

Regards.

Could s.o please tell me how to make the left solid curve like the right one please?

Maybe it's possible in Inventor but in AutoCAD I would say it is impossible to bend the one on the left. However, I think you might be able to approximate it. Can you post and actual DWG file?

[MSasu]

If you read again the above posts, will find the answers to both questions, but I will resume them for you.

Check the method I suggested in this thread; use the items from your picture, just extrude more the shape on the left and intersect it with the shape from the right side.

There isn't a bend command in AutoCAD, but I don't see why the part couldn't be made in AutoCAD from a Thickened trimmed surface.

Use PRESSPULL, and do as Mircea suggests, creating enough depth on the left side flat piece to use the INTERSECT or INTERFERE command to create a new part from the common shared volumes in those 2 shapes.

nestly did a nice video which will show you how to do this within the last 3 weeks, showing how to model an offset wrench.

Project geometry works too.

just cut that shape out and your good to go

[nestly]

INTERSECT, as mentioned above, will give a reasonable representation, but not exactly as it's likely to be manufactured.

Hi Nestly,

 

Thanks for the nice illustration, but I see that it cannot be exactly. As the part is curve and all the holes inside should be curve too, haiz, thank everybody, and I appreciate if s.o can figure out how to do this exactly.

As nestly mentioned it is not exactly as it would be if bent, but that could be done by orienting the elements to be subtracted radially.

Thickened trimmed surface.

Once again, JD's solution, on second perusal, is spot on.
